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

If you still doubt that you can complete the work of replacing the toilet yourself, we will dispel your doubts. Next, we will talk about how to properly remove old plumbing and what tool will be required for this.

When to start dismantling the toilet?

The need to replace an old toilet bowl with a new one arises at the most unexpected moment - a plumbing product may burst or crack if something heavy is accidentally dropped on it. Although the repair was not planned, it is not possible to live without a toilet.

In an emergency, you have to evaluate the front of future work, carefully study the shape of the toilet, how it was connected and acquire a model that has similar characteristics. It will allow replace the toilet out of order with minimal cost.

Toilet crack
If the crack on the toilet is not significant, then the replacement can be delayed by quietly planning the time of work. Yes, and to choose the purchase of new plumbing, it will take a day or two

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

In this case, you can choose the model that best fits the idea of ​​an ideal toilet - anyway there is an extensive front of work and the replacement of pipes will most likely be one of the points.

Toilet bowl badly damaged
When the product is damaged and completely unsuitable for use, act immediately. In this case, the dismantling and installation work is best done on their own, so as not to overpay for an urgent plumbing call

Before you begin to dismantle an old or broken toilet, you must definitely buy and wait for the delivery of a new product. Also, you must immediately check whether there are all the accessories that will be needed when replacing.

Models, the release of which is embedded in the floor, look aesthetically pleasing, but in the event of a pipe leak, you have to remove the tiles and crack the floor - it is difficult, long and expensive

Safety measures before starting work

When you plan to replace the toilet, there are doubts about the advisability of doing all the work yourself. In fact, you can cope on your own with the removal of the old and the installation of a new device. The main thing is to do everything sequentially, following the recommendations of the manufacturer and following the advice of experienced craftsmen.

There are 3 options for the work:

  • invite plumbing;
  • invite shabashnik;
  • do it yourself.

The first option is suitable when there is a scheduled repair and there is no time limit. Sometimes plumbing has to wait weeks - he constantly has unforeseen circumstances.

Inviting a cobbler can result in even more expenses - it’s good if you get an experienced craftsman whose hands grow from the right place. Otherwise, he can destroy the entire bathroom.

Dismantling the toilet with a sledgehammer
Some co-workers love to dismantle the toilet with a sledgehammer. It is fast and does not require much work - a couple of swings and no toilet

The last option of independent work is the most profitable - you can get practical experience and money will be saved. Yes, and large destruction can be avoided.

If it was decided to get practical experience in dismantling the toilet, then we must not forget about safety measures, because in the process of work various tools can come in handy.

Care should be taken to protect the eyes, hands, other important organs and parts of the body. To do this, wear special glasses, tight gloves, a face mask to protect the respiratory system. Clothing should completely cover the arms and legs, so that sharp fragments do not accidentally damage the skin.

You may have to use a grinder - so you can’t do without protective glasses and gloves

The technology of dismantling old plumbing

Having decided to disassemble the toilet yourself, you need to familiarize yourself with the theoretical part and only then proceed with the practical application of the knowledge gained. Only having a full idea of ​​what remains to be done is it easy to develop an action plan and act according to it.

To get an initial idea of ​​a typical sequence of work on the removal of plumbing, consider the process of dismantling a toilet with a direct release:

The first stage: preparation of the facility

The first step is to carry out preparatory work, carefully examining the toilet and all fixtures. This will help determine the set of necessary tools for dismantling.

Then you should clean the bathroom as much as possible from unnecessary items - take out basins, buckets, a washing machine, if it will interfere with free access to the toilet. In a word, it is necessary to remove from the room everything that can interfere or there is a chance of accidental damage.

Work in gloves
Better not to start working without gloves - the risk of injury or a deep cut is very high

Preparing an object for deletion consists of the following:

  • preparation of the necessary tools;
  • washing the product from surface contamination;
  • shutdown of the water supply system;
  • removal of water from the drain tank;
  • preparation of dry cuts of fabric, old towels or sponges and other soft materials that can absorb water.

It is important to carefully inspect all fasteners - if you used silicone sealant for sealing, then you will also need a construction knife to remove it.

Easy to cut sealant with a construction knife
With a construction knife, it is easy to cut off the sealant that is firmly glued. Residues can also be removed with a special silicone remover or with solvent P646

Also, regardless of the model of the toilet and the location of the drain tank, you have to turn off the tap on the pipe that brings water to the house / apartment. Then you need to check whether everything worked out by opening the tap for this. If the water does not flow, then everything is possible and preparatory work can continue.

Water must be drained from the tank so that it does not interfere with further dismantling. Dry sponges, old towels and floor rags are useful for wiping puddles and making an impromptu gag to close the entrance to the sewer socket.

This measure partially protects the residents of the apartment / house from the penetration of an extremely unpleasant smell from the sewer riser after dismantling the toilet.

Overlap of a water supply pipe
It is necessary to block the water supply pipe in any case - water should not interfere with work

If the toilet is embedded in the floor or the cistern is in the wall, you will have to remove the tiles, freeing access. Also, do not forget about the tanks built into the wall.

When dismantling such products, serious damage cannot be avoided.Work on removing tiles, removing decorative coatings or panels should be carried out in advance, at the preparation stage.

Separate tap on a flexible eyeliner to the toilet bowl
It is convenient if there is a separate tap that will allow you to shut off water to the drain tank without resorting to a complete shutdown of water in the apartment / house

Second stage: dismantling the tank

When the water is shut off, you can proceed to the next step - remove the drain tank, not forgetting to first free it from the water. Moreover, it does not matter exactly where and in what way it was installed. If the tank is hidden in a wall niche, then you have to break the decorative structure, remove the tiles, trim panels and other types of finishes.

Then you should carefully remove the lid from the tank - this will prevent its accidental fall during dismantling. If this is a model of a drain tank with a button, then first you have to unscrew the button, and only then remove the cover.

Dismantling the drain tank cap
The lid of the drain tank can not be removed, but then it is likely that during the work it will fall on your foot or even break, injuring someone with fragments

When the lid was removed, it must be removed from the room so as not to interfere with further work. Now you need to unscrew the flexible eyeliner that supplies water to the tank. To do this, use a key of the appropriate diameter and carefully unscrew it, being careful not to damage the adjacent walls.

Dismantling the flexible eyeliner of the drain tank
If the new toilet has the same arrangement of all the holes for connection, and the flexible eyeliner is in excellent condition, then its second end can be unscrewed

Then you need to unscrew the bolts securing the tank to the wall, if any. If the drain tank is on the toilet shelf, then the bolts that hold the tank in a fixed place will have to be unscrewed.

A grinder may come in handy to dismantle an old toilet
It happens that a compact toilet bowl + cistern has served for many years and the fasteners are fastened tightly. In this case, you may need a grinder to remove the bolts

It remained with smooth movements to remove the tank and remove it from the bathroom. It is important to act confidently - if the first time it was not possible to remove the container, you need to try again one or two, applying great force. If out of order only toilet bowl, then you can replace it only, without proceeding to the complete dismantling of the product.

The tank must be removed very carefully.
The main thing is to act smoothly, slowly, with power swing the tank from side to side, trying not to drop

Stage Three: Removing the toilet bowl

When the tank is removed, you can proceed with the removal of the toilet bowl itself. To do this, it is advisable to first release it from the cover by carefully unscrewing the bolts that hold it in place. It is important not to damage anything - often the mistress buys a cover separately, choosing an expensive, beautiful and comfortable seat.

Removing the toilet lid
The lid can not be removed, but then it can be accidentally broken during dismantling and it will not be possible to use it in the country together with the toilet

Now you have to unscrew the bolts securing the sole of the toilet to the floor. This stage can be simple or more complex - it all depends on the method of attachment:

  • if the toilet is fixed only with bolts, then they need to be unscrewed;
  • when sealant is used as a sealant, you will need a knife to gently cut off the silicone layer;
  • if the base of the toilet is concreted on the floor, you will have to use a chisel, hammer, and sledgehammer.

It happens that the sole of the toilet is attached to a thick wooden board embedded in the floor. After 10-25 years of using the plumbing fixture, a board called taffeta rots. Therefore, it is not difficult to remove the toilet, but the board also needs to be removed.

When the bolts are tight
Sometimes the bolts stand tight and can not do without destructive actions. In this case, you need to apply a strong point blow to the hammer next to the bolt on one and the other side of the sole of the toilet

The next step is to remove the drain from the toilet. The front of work will depend on the material from which it is made.

It could be:

  • flexible discharge;
  • plastic;
  • cast iron.

If the first option can be easily pulled out flexible discharge from the toilet, then in the second and third case you have to work hard, removing it.Particularly difficult may be the work of removing the cast-iron pipe.

Dismantling an old toilet
To disconnect a cast-iron pipe, a chisel or drill may be needed to pick out flax from the joints

If the plastic drain does not lend itself in any way, it can be sawn with a hacksaw for metal or cut with a hot knife.

Then clean the pipe from all types of windings, for many years ensuring tightness and protecting against leaks.

The knife will help remove the flexible drain.
When the toilet cannot be pulled out of the flexible drain, you can carefully cut the plastic with a knife

Remained with strong swaying movements to remove the toilet without damaging sewer pipe. It is important to act smoothly.

If nothing happened the first time, you don’t need to immediately take up the sledgehammer - you should repeat the process a couple more times and everything will work out.

Broken Toilet Shards
When a sledgehammer is used to remove the toilet, fragments can injure yourself and damage the tiles on the floor and walls

It remains to take out the dismantled bowl from the bathroom so that it does not interfere with further work.

Fourth stage: sweeping the territory

The volume of work at the last stage completely depends on the previous stages and on what material the drain is made of. If we are talking about a cast-iron pipe, it will have to be removed to replace it with a lighter and more flexible flexible drain.

Cast iron drain
Remove the cast iron pipe carefully so as not to damage the entrance to the sewer

It happens that removing the pipe and cleaning the inlet can take more than 2 hours. But this is justified, because in the future the process of dismantling the plastic corrugated pipe will take a few minutes.

Yes, and leakage, if it occurs, is much easier to eliminate than in cast iron.

After careful dismantling
If everything is done calmly and smoothly, then there will be a minimum of garbage, and cleaning will take about 20-30 minutes

When the toilet was attached to the taffeta, it is necessary to remove all the remnants of the rotten board and install a new one in its place, using grease glue and fastening it to the screws. Or you can immediately fill the hole with a solution.

The floor in place of the old toilet
Install new plumbing only after the solution is completely dry

If, out of ignorance, the toilet was not removed, but knocked out using a sledgehammer or other heavy tool, then cleaning the bathroom will take a long time.

To carefully clear the place for installing new plumbing, you will have to make an effort.

Lots of shattered toilet shards
Broken toilet fragments can spoil the wallpaper, tiles and other decorative coating in the room

Acting smoothly and accurately, you can remove the toilet without damaging anything. He will be fully ready for installation in the country.

Properly removed old toilet
The old toilet bowl, the dismantling of which is done correctly, will be able to serve for many more years in the bathroom of a country house

    During the overhaul of the bathroom, accidentally broke the toilet. The model was embedded in the floor, fooled for a long time with the dismantling of tiles around. Dismantled it on the same day, I still did not have a new one, so I installed the new one only two days later. I had to plug a sewer bell so that the smell would not go throughout the apartment. In general, there is nothing complicated, I managed it myself, although I did it for the first time.

    I believe that you do not have to take risks and try to do this work yourself, unless, of course, you are a plumber by profession. In theory, there is nothing complicated, however, if something is done wrong, it will still be necessary to call a specialist. Does anyone think that watching a video from the Internet is enough? As they say, avaricious pays twice. It is necessary to soberly assess their capabilities.

      Breaking - not building. There is nothing complicated in the dismantling of the toilet, and it’s difficult to screw up in this matter. This is just the case when you really learn how to video from the Internet.

    • Vyacheslav

      I’ll tell you more than that - in addition to dismantling, installing a new toilet is also one of those cases when you can watch a video and do it right yourself. Provided a meaningful approach to business, of course. To dismantle the old plumbing, so generally a trifling matter. On the other hand, I personally know people who have never taken a tool in their hands, and when it comes to breakdowns in plumbing or electrics, they start to panic.
