The reasons for the leakage of the toilet at the junction with the sewer

 What to do if the toilet is leaking at the junction with the sewer

The procedure depends on the zone and the cause of the leak.

The junction of the bowl and the cistern is leaking

If the plumbing parting has worked for you for some time, then, most likely, a leak was formed due to the fact that the gasket cracked or the drain tank was warped. What to do if water oozes due to the fact that the gasket has served its purpose is clear without long explanations. It needs to be replaced. We do everything according to the instructions:

• we shut off the water and empty the drain tank;
• wipe the inside of the tank dry so that not a drop of moisture remains there;
• disconnect the supply hose;
• unscrew the fastening screws holding the tank and remove it;
• remove the lock nut on the drain;
• remove the old gasket and replace it with a new one - it is better to put the gasket on the sealant immediately, it should not differ in shape and size from the old one;
• we assemble in the reverse order.

We supply water to the tank and admire the result of our labors.

Corrugation leaks

To troubleshoot, ideally, it is better to remove the toilet in order to have more room to work, but you can do without this. What is needed is to remove the corrugation, which has worked its way out, and clean up the landing sites.

The surface of the corrugation and the seats must be treated with silicone sealant. The fit should be snug. After two hours, when the sealant has set, you can check for leaks.

In cases where dismantling the toilet is impossible or there are difficulties, and the corrugation cannot be removed, there is one trick:

• the toilet must not be used for at least a day;
• climbing under the device, use a stick made of wood or plastic;
• at the place where the corrugation connects to the toilet, pry it off;
• wringing out the corrugation, apply silicone sealant inside;
• gradually passing along the entire perimeter, treat with a sealant.

Loose bolts

Loose bolts simply need to be replaced with new ones. Everything is done very simply:

1. The water is shut off and the drain tank is emptied.
2. The supply hose is unscrewed.
3. The bolts are dismantled - you need to act with extreme caution, since they have corroded from time to time and it is difficult to move them.
4. New bolts are installed, the main thing is not to forget about the gaskets - the bolts must be tightened tightly, but not particularly zealous.

Attention! If the leak continues, then the bolts are tightened slightly additionally. The main thing is not to overtighten, otherwise it may burst somewhere.

Leaking pipe

Very often, pipe leaks take place where the toilet is standing on cement mortar. Such an installation was very often used, and it is also used in old houses, where there has been no major repair for a long time. The technique is simple and reliable, but over time, the pipes leak. The fact is that the coating gradually crumbles and falls off. This leads to leaks. The remaining solution enters the sewer, and the flow expands more and more.

What is the right thing to do in such cases? It is necessary to act as follows:

• arm yourself with a chisel with a narrow sting or a flat screwdriver and a hammer;
• beat off all the old plaster - do not hit too hard, otherwise you will beat off the release of the toilet bowl;
• clean everything from dirt and debris;
• fill in the remaining voids.

Cement mortar can also be used to seal. Just dilute with water one part sand and one part cement. But this is already the last century. Silicone sealant is much more convenient and effective. Yes, and it is in all hardware stores.

Before buying, consult your dealer for the best sealant. Sanitary sealants are usually used, since they have better adhesion to the sanitary ware, from which the toilet is made.

If everything is done accurately, but the leak has not been eliminated, the best option would be to invite specialists. They will be able to quickly and efficiently eliminate all faults. If the pipes in your house, like the plumbing, have long outlived theirs, then it would be wiser to update them.
