How to dismantle an old toilet

Since all plumbing in an apartment or house must always remain in working order, it must be changed periodically. Therefore, in any case, you will have to face the problem of dismantling the toilet before installing a new one. It is possible to do this with your own hands. Removing the toilet is not a pleasant job, but it is done quite quickly and easily. Dismantling a toilet includes the following stages: the preparatory stage, freeing the base of the toilet from the floor, dismantling the toilet from the sewer system and installing a temporary plumbing fixture.

Dismantling of an old toilet must be done with extreme care, without damaging the sewer system, as well as existing repairs.

Preparatory work before removing the toilet

Removing a toilet and attaching a temporary plumbing fixture is not as difficult a task as it might seem. In order to dismantle the toilet before its subsequent replacement, you need to stock up on the following materials and tools:

• crowbar;
• wrenches of different sizes;
• pliers;
• rags needed to get rid of residual water;
• latex gloves;
• disinfectant.

When dismantling the toilet, be sure to wear rubber gloves, this will help you avoid microtraumas and infections. Before starting work, the plumbing fixture must be thoroughly washed and treated with a disinfectant, for example, a chlorine solution. It can be rinsed with water with an antiseptic dissolved in it - ordinary chlorine-containing bleach.

After this, the workspace must be cleared of all foreign objects; everything should be removed, even rugs.

Removal of plumbing should begin by shutting off the cold water in the supply pipeline. The remaining water in the tank must be drained and the sewer system rendered inactive. You should not use water yourself, and you should also warn your neighbors above so that they refrain from water procedures for a while. After making sure that the supply valve is shut off securely, you can begin work.

Freeing the toilet base

Work begins by disconnecting the flexible water supply hose. Then you will need to dismantle the flush tank, because removing the toilet together with the tank will be quite problematic. To do this, drain the remaining water, unscrew the fastening nuts located on the rear side of the structure, and open the lid. The tank, hanging on hinges on the wall, can be removed without opening it.

Next you need to free the base. If the tiles in your bathroom are beautifully laid, you will have to knock them out. The toilet is attached to the floor in two or four places at the bottom. The connection can be a nut connection, when the device is mounted into the floor using studs, or using dowels with hexagonal heads. However, in both cases, the fastener will be unscrewed with a wrench of the required size.

When connecting with studs, slightly lift the base and, with light rocking movements, loosen the seal in the sewer outlet pipe. If the socket seal was made using cement mortar, it must be chipped using a chisel before removal. It is best to use a thin chisel, breaking off the cement very carefully, with light blows - the tip of the chisel should be directed across the coating, otherwise the toilet outlet or pipe socket may be damaged. As soon as the coating cracks on one side, the same operation will need to be done on the other side of the outlet. They pick out the fragments and try to get the toilet bowl out of the pipe. If this does not work, you need to continue chipping the cement.

If you are faced with such a complex mounting option as fixing the toilet on a wooden board, then dismantling the plumbing can lead to damage. The bottom will simply have to be beaten off. The fastenings will remain in the floor along with the base, which will be removed in parts after the work is completed.

Old plumbing fixtures are usually thrown away; you shouldn’t feel sorry for them.

To avoid injury during work, carefully follow all safety precautions - use gloves and safety glasses.

Freeing the toilet from the sewer pipe

The toilet is now connected only to the sewer cast iron pipe, and it can be disconnected in several ways. These methods have different degrees of damage caused. Before removing the device, it is recommended to make a plug that looks like a rag gag, about 10 cm in diameter. She will need to plug the hole in the sewer pipe, thereby preventing sewer gases from escaping into the apartment.

The first way is destruction. According to this method, you will need to remove the outlet, take out the toilet and simply clean the pipe of any remaining ceramics and mortar. The outlet can be broken off if the device is no longer attached to the floor; in this case, it is necessary to clean the connection between the outlet and the pipe as much as possible from the cement mortar. The toilet is lifted and pulled up. All that remains is to clean the sewer pipe of any residue, being careful not to damage it. The sewer pipe must be protected from clogging with fragments; it is better to plug the hole with something.

You can choose a less destructive method if you are trying to keep your plumbing intact. The joint between the sewer pipe and the toilet must be cleaned of mortar, sealant and other impurities, removing even the smallest residues. Lift the product and determine how freely it moves in the pipe. Slowly loosening and turning the outlet, it is necessary to pull it out of the socket, while clearing it of the solution. The pipe needs to be cleaned for upcoming installation.

Some types of plumbing fixtures can be easily replaced yourself. Therefore, knowing how to remove an old toilet will come in very handy - you won’t have to call a plumber and adjust your plans to suit his mood.

And the money saved on the dismantling service can be used to purchase more useful items. If you still doubt that you can carry out the work of replacing the toilet yourself, we will dispel your doubts. Next we will talk about how to properly remove old plumbing fixtures and what tools are needed for this.

The need to replace an old toilet with a new one arises at the most unexpected moment - a plumbing product may burst or split if something heavy is accidentally dropped on it. Although no renovation was planned, it is not possible to live without a toilet.

In an emergency situation, you will have to evaluate the scope of future work, carefully study the shape of the toilet, how it was connected, and purchase a model that has similar characteristics. This will allow it to fail at minimal cost.

If the crack on the toilet is not significant, then you can postpone the replacement, calmly planning the time for the work. Yes, and it will take a day or two to choose to buy new plumbing fixtures

If the time has come for a major overhaul, then the form of release, the supply of water to the drain tank, and the shape of the product itself will not be of fundamental importance.

In this case, you can select the model that most closely matches the idea of ​​an ideal toilet - there is still a lot of work to do, and replacing pipes will most likely be one of the items.

When a product is damaged and completely unusable, action must be taken immediately. In this case, it is better to carry out the dismantling and installation work on your own, so as not to overpay for an urgent call to a plumber

Before you begin dismantling an old or broken toilet, you must buy and wait for the delivery of a new product. Also, you need to immediately check whether all the components that will be needed for replacement are available.

Models in which the outlet is embedded in the floor look aesthetically pleasing, but in the event of a pipe leak, you have to remove the tiles and break into the floor - this is difficult, time-consuming and expensive

Safety precautions before starting work

When you plan to replace a toilet, doubts arise about the advisability of doing all the work yourself. In fact, you can handle removing the old and installing a new device on your own. The main thing is to do everything consistently, following the manufacturer’s recommendations and following the advice of experienced craftsmen.

Properly installed plumbing fixtures can last for years. However, everything has a certain service life and the time comes when it becomes clear that replacing the toilet is inevitable. For many, this procedure does not cause much trouble: you just need to call one of several dozen companies providing plumbing services, and the specialists will carry out all the work in a matter of hours. However, for a number of reasons this may not be possible and then the equipment will have to be changed independently.

What do you need to prepare before work?

First of all, you should buy a new toilet. To do this, you need to understand the design and dimensions of the old one. We measure the room in detail and make a simple drawing on which we indicate the installed toilet and the sewer and water pipes connected to it. Check the angle of the waste neck. As a rule, it is 45°, but it is better to double-check this. If you have to carry out such work for the first time and have very little experience, you can take a photo of the structure with your phone before going to the store in order to consult with the seller about the type of new device.

It will be much easier to choose a new toilet based on the drawing and photo. We pay attention to the dimensions of the device, shape and design features. On sale you can find devices with different depths and bowl shapes, drainage hole slopes and flush designs. Let's not forget about design. Among the various shades and materials, you should choose the best option for your room. With other identical parameters of the device, it is worth giving preference to equipment from well-known companies that produce higher quality products.

A marker will be needed to mark the structure. It is lowered into the mounting holes and marks are placed on the floor under the holes, then the device is traced along the contour

In addition to the toilet, you should purchase a small set of items necessary for installation:

• Water hose. Its length is measured using the old part, the new one is taken with a small margin.
• Toilet mounts. They may come with the equipment, but if not, you need to purchase them.
• A flexible corrugated pipe or corrugation that connects the toilet to the sewer.
• Cistern. You should check the contents of the tank. If the drainage system is not included, it will have to be purchased separately.

You will also need silicone, but not acrylic, sealant, white or transparent, as well as fum tape and gaskets for water pipes. Among the tools, you cannot do without a hammer drill with a set of drills; it can be replaced with an impact drill with drills, a hammer, a set of screwdrivers and wrenches, a marker, a sharp knife and a chisel. Having prepared everything you need, you need to think about how to remove the old toilet.

Dismantling the old structure

Before starting work, you should prepare buckets and a large amount of rags. We start by disconnecting the water pipe from the drain tank from the device. Drain as much water as possible and unscrew the tank. The toilet is ready for dismantling. If it is very old, then most likely it was installed with mortar. In this case, you need to prepare for the fact that it will not be possible to remove the device intact. Especially if its neck is packed with rags with paint.

Among the recommendations on how to remove the toilet easier, you can find advice to start work from the drain neck. This is true. It is best to hit the neck hard and, having split it, disconnect the device from the pipe. In addition, the vibration from the impact will somewhat rock the base of the structure, fixed in the mortar, which will facilitate further work. Important note: Do not hit directly on the drain pipe. If it is cast iron, which most of the cases are, it is very easy to crack, which will lead to additional problems.

Shards of the old toilet should be carefully removed. We clean the neck of the sewer pipe from contaminants, otherwise it will be impossible to carry out a high-quality sealing of the new device

Having broken the neck, we begin to disconnect the device from the floor. If it cannot be rocked and does not move, take a hammer and use a chisel to start chipping the structure away from the base. It is quite possible that as a result of this work, water will flow from the broken device. It needs to be collected with a rag in a bucket. We break off the fragments of the toilet bowl, remove the remains of the mortar in which it was fixed and, if possible, level the floor. We clean the edge of the drain pipe from fragments of the neck. It is best to do this with old screwdrivers or use a chisel. We perform the operation very carefully so as not to damage the pipe.

Methods for installing new equipment

After dismantling the old toilet, you should repair the floor, if this was intended, or simply level it as much as possible before installing new equipment. There are several ways to install a toilet.

Method #1 - installation on taffeta

This is the traditional way to install a toilet. For it you will need taffeta, which is the name of a hardwood board that has been carefully oiled. It is placed in the floor under the base of the device so that it is level with the floor covering or slightly raised above it. The wooden base should be securely fastened to anchors and the resulting recess should be filled with cement mortar. After the surface has completely dried, you can begin installing the device.

Taffeta, a carefully oiled hardwood board, is installed in the floor in the place intended for the toilet. A layer of solution is applied on top of it

The equipment outlet is connected to the drain pipe, then to the socket of the sewer system pipe. All connections are treated with sealant and sealed with tow. The equipment is installed in the desired place and firmly secured with screws, under the heads of which rubber washers must be placed. The drain tank is installed and the system is checked for leaks. The device is ready for use. It should be noted that this method of dismantling and installing a toilet is perhaps the most labor-intensive compared to others.

Method #2 - glue connection

As practice shows, plumbing fixtures can be installed using epoxy glue. To do this, the contacting surfaces should be carefully prepared. They are cleaned and degreased with white spirit, solvent or acetone. They are made rougher, degreased again and dried.

After connecting the outlet of the device and the sewer system, an even thin layer of epoxy adhesive is applied to the supporting surface. The toilet is placed in the prepared place and pressed firmly to the floor. After which it is kept until the glue is completely cured, which will happen no earlier than after 12 hours.

Method #3 - mounting on dowels

Installing a toilet with dowels involves fixing the device directly to the floor, without first installing any structure under its base.

The most practical way to change a toilet can be considered the method of fastening with dowels. During the work the following operations will be performed:

• Trying on the device. We install the toilet on the prepared base and check the coincidence of the height of the neck and the waste pipe, the angle of inclination, etc. If there are inconsistencies, we make the necessary adjustments.
• We mark the structure. We measure the width of the room, find the middle or axis of the toilet. We install the device on it at a distance of 10-15 cm from the socket of the waste pipe. We insert a marker into the mounting holes, make marks for the holes, and outline the base.
• We assemble the drain tank. In accordance with the instructions, we assemble the device, and then attach it to the toilet. To be completely confident in the quality of the work performed, you can reinstall the device in place, connect it to the sewerage system and water supply system and conduct a test run. Having made sure that everything is in order, we drain the water and continue to carry out work on replacing the toilet with our own hands.
• Preparing the mounting holes. Using an impact drill or hammer drill, we make holes in the designated locations. We hammer plastic dowels into them.
• We seal the corrugation. We wipe the pipe dry with a rag and apply silicone liberally with a wavy strip to the ribs of the gum, which will be hidden in the drain pipe. We carry out a similar operation from the opposite end of the corrugation, lubricating the area that fits onto the neck of the toilet.
• We connect the device to the sewer. We insert the corrugation into the sewer pipe up to the edge of the elastic, and on the other side we firmly place it on the outlet of the equipment. On the toilet seat, which was previously outlined with a marker, we place a special rubber gasket or apply a thick layer of silicone.
• We install the equipment. We place the device in the prepared place, press it and screw it to the floor. Remove excess silicone squeezed out during installation with a wet finger, running it along the contour of the device.

Installation is complete. You can conduct a test run of water. If the work is carried out correctly, the tank is filled to the required level and the flow of liquid stops. There is no overflow. After draining the water, the cycle repeats. You should also check that the equipment is not leaking anywhere. If everything is so, then the installation can be considered successfully completed.

Recommendations on how to change a toilet with your own hands are quite simple. Even a novice plumber can do them. You need to carefully study the instructions, prepare everything you need and carry out all stages of installation without haste. The result will please all household members. A properly installed toilet will reliably serve them for many years.

Surely every owner has thought about updating the interior of a house or apartment. In particular, this applies to the bathroom. When carrying out major renovations, owners often encounter problems with dismantling old plumbing. Dismantling and installing a toilet is a very difficult task. However, anyone can do this kind of work with minimal experience and tools. Later in the article we will look in detail at how to dismantle an old toilet with your own hands.

Preparation

First we need to prepare the work area. To do this, remove all rugs and shelves from the bathroom. Make sure there are no fragile parts nearby. We will also need working tools, namely:

• pliers;
• hammer;
• chisel;
• hacksaw for metal;
• wrench;
• stationery knife.

Additionally, you will need a basin, rubber gloves, safety glasses and rags.

Before dismantling the toilet with your own hands, you need to turn off the water in the riser. Next, all the liquid from the tank is drained into a basin.

Phased dismantling

First you need to remove the toilet seat. This can be done using a wrench. Then the lid and support are removed from the tank. Next you need to find the elements that secure the tank to the wall. Typically the element is secured with bolts or nuts. They should be unscrewed using a tool.

What to do if the bolts are rusty?

Please note that fasteners may rust. In this case, you should use a hacksaw for dismantling. We cut off the necessary bolts and move on to the next stage.

We continue work

When cutting off the last nut, try not to break the tank - call an assistant to hold part of the toilet. Next you need to disconnect the pipes that are supplied to it. To do this, use an adjustable wrench. Pay attention to the way the toilet is mounted. It is usually installed to the floor with bolts and sealant. Using a sharp blade (you can use a utility knife), we cut the sealant.

Next, unscrew the bolts. If they are also rusty, we use the same method with a hacksaw. Then slightly raise the toilet. You need to move it relative to the main sewer pipe. Next, we proceed to dismantling the bell. To do this, you need to slightly scroll it and shake it in different directions. Often it is immediately disconnected after dismantling the corrugation.

When dismantling the toilet, try not to contaminate the sewer drain pipe. If debris gets in there, it can cause serious blockage in the system.

After this, drain the remaining water from the siphon. To do this, lift the edge of the toilet. Next, install the container and plug the pipe pipe with a rag. If this is not done, the smell of sewage will spread throughout the apartment. This completes the dismantling of the toilet.

Installation

Installation should be done only after finishing work has been completed, that is, on tiles or on a flat, cemented surface. Installation begins by connecting the device to the sewer. For this purpose, a corrugated outlet is used.

It is better to purchase a new element - it is unlikely to work with the old toilet. Next, a rubber seal is put on the toilet outlet pipe. The latter is pre-moistened in water. Then the toilet is installed in the chosen place and the second end of the corrugation is attached to the sewer pipe.

At the base of any modern toilet there are mounting lugs. Through them, using a marker or pencil, marks are made on the floor. Disconnect the corrugation from the sewer outlet and move the toilet to the side. This will free up space for drilling holes in the marked places. During the work we will need a hammer drill. The diameter of the hole must correspond to the plugs that come with the toilet mounting kit. You will also need special drills with pobedit tips. They are suitable for working with concrete and tiles.

Next, the toilet is returned to its original place. It is necessary to align the holes made with the factory ears. Fastening is carried out with bolts or using long screws with a hexagonal head. Pay attention to the tightening torque. It is important not to overdo it so as not to deform the ceramic floor tiles.

The final stage of installation is to seal all joints where the toilet comes into contact with the floor.

If the toilet has no ears

There are also such plumbing fixtures. In this case, installation is carried out using epoxy adhesive or cement mortar. But in order for the connection to be of high quality, it is necessary to ensure maximum cleanliness of the surface. For this floor, all dirt and dust are removed.

We fix the drain tank

So, the main part of the toilet has already been installed. All that remains is to secure the drain tank and connect it to the water supply. To do this, we use two bolts and a rubber gasket. The latter is put on the outlet side of the cistern. Long bolts with washers are installed in special holes. Next, the tank is installed in its place.

It is necessary to align all the holes, namely two mounting holes and one drain hole. The bolts are tightened from below with plastic nuts with so-called wings (metal “turnkey” ones will not work, otherwise the element may be damaged). One hand is enough to ensure a tight connection.

Connection to water supply

Now you need to connect the toilet tank to the water supply system. To do this, use a flexible hose with nuts at both ends. You can see what this element looks like in the photo in the article.

It is important to ensure maximum tightness. For better sealing, you should use FUM tape, but sometimes rubber gaskets are included with the hoses.

At this point, installation and dismantling of the toilet has been successfully completed. After which you can turn on the water supply system. The plumbing will be fully usable after the sealant has completely dried.

Conclusion

So, we found out how to install and dismantle a toilet. As you can see, all the work can be done with your own hands. When dismantling the toilet, try not to break the tank - it is very heavy and flimsy. The help of a second person will not be superfluous. Also, do not move the toilet yourself. The weight of a ceramic product can reach thirty kilograms.

How can you dismantle a toilet yourself? In this article we will look at several typical methods of attaching toilets and cisterns. For each case, the sequence of dismantling operations will be described.

Removing the tank

Dismantling and installing a toilet implies that the old tank is removed. Let's start with this operation.

Upper tank

Given: the tank is fixed to the wall using studs welded to a steel strip. The strip, in turn, is aimed at the wall with a mounting gun.

Connects to the toilet with a rubber cuff.

1. Turn off the water to the tank and disconnect the liner.

Please note: in old houses you can find a rigid connection to the tank.
The fill valve is screwed into a cast iron coupling screwed onto the pipe thread.
To disassemble without tearing the outlet from the riser, be sure to burn it with a blowtorch or gas torch.

1. Remove the tank cover.
2. Unscrew the nuts that hold it on the studs.
3. Pushing the drain pipe back, remove the cuff from the toilet flare.
4. Remove the tank from the studs and place it on a flat surface.

Compact of domestic production

A characteristic feature of its design is a separate shelf.

It is connected to the toilet socket by a cuff, but not in the form of two cylinders of different diameters, as in the previous case, but in the shape of a truncated cone.

1. Turn off the water and turn off the water supply.
2. Unscrew the bolts between the toilet and the shelf. If they are plastic, this is easy to do with bare hands; for brass ones you will need pliers or open-end wrenches. Steel bolts will inevitably rust over years of use; It’s better to cut them down using a hacksaw blade.
3. We bring the shelf back and release it from the cuff.
4. Remove the tank and place it on a flat surface. Then remove the cuff from the toilet flare.

Imported compact

It is also better to start dismantling a toilet bowl - old or broken - of an imported model by dismantling the tank.

1. Turn off the water supply and drain the water.
2. Unscrew the bolts that attach the shelf.

Tip: look under the shelf.
It is quite possible that no tools will be needed: in many kits, the nuts are equipped with convenient wings.

1. We remove the tank and remove the ring gasket from the shelf.

Dismantling the toilet

What removing an old toilet looks like depends on how it was installed and whether you want the old set intact.

Screw installation

The simplest dismantling operation is when the compact was installed on standard fasteners, and the outlet is connected to the sewer socket with a rubber seal or cuff.

1. Remove the decorative caps on the top of the sole. Under them you will find screw heads for a screwdriver or open-end wrench.

1. Unscrew the screws (there are 2 or 4 of them).
2. We pull the outlet out of the socket. It is done.

Installation on taffeta

In post-war construction, it was widely practiced to install kits with an upper tank on taffeta - a thick board laid in a recess in the ceiling.

Please note: the deplorable condition of these boards is largely due to violations of installation technology.
Initially it was intended to use only oak boards; however, for reasons of economy, pine and other rot-resistant species were used.

The main problem is that the outlet is usually caulked into the sewer socket.

How to dismantle a toilet intact?

1. Armed with a strong screwdriver and a small hammer, break up the cement putty around the outlet.
2. Using the same screwdriver, we try to extract the maximum amount of bonding from the socket - the oiled organic fiber with which the joints were minted.
3. Then we unscrew the screws (or simply pull them out of the rotten board) and, slightly shaking, pull the outlet out of the socket.

Installation on cement

Installing and dismantling a toilet with cement mortar leaves little chance of reusing it. Covered with solution to the entire depth of the socket, the outlet usually splits when trying to remove it.

If you still want to try, go ahead.

1. Use a screwdriver and hammer to knock out as much cement as possible from the socket.
   
2. Then, with moderate force, we kick (with shoes on, of course) from the bottom up under the bowl in front. After one or two blows, the sole will be released. Whether the issue will survive depends entirely on luck.

Conclusion

As you can see, dismantling the toilet with your own hands is not particularly difficult. The video contains visual information on this topic. Good luck!
