Toilet installation repair: how to fix leaks and other problems

09.07.2020 09:46

High-quality installation systems from trusted sanitary ware manufacturers offer not only space savings and easy maintenance. They are reliable: they are equipped with durable steel frames, solid cast tanks, drain mechanisms with emergency overflow with a siphon effect and are easy to maintain. Repairing the toilet installation does not require dismantling the dividing partition or lightweight frame wall with cladding. To access all functional units and troubleshoot problems, simply open the inspection window by removing the horizontal or front flush button. All fittings easily pass through the hole.

Features of toilet cistern installation mechanisms

In most cases, repair of a wall-hung toilet is associated with problems with the drain and fill fittings of the tank. The operation of all installation mechanisms is interconnected. When you press the flush button, the drain valve opens and the specified volume of water goes into the bowl. As soon as the drain valve closes, the filling mechanism is activated. As soon as the tank is full, the water supply will automatically shut off.

The fittings for concealed tanks have a simple operating principle. It suffers from natural wear and tear of rubber and silicone components due to hard water or deformation of plastic parts.

Adjusting the water level

Violation of the optimal volume of filling the installation tank leads to unstable flushing at low levels or excessive water consumption at high levels. You can easily adjust the required amount of liquid with your own hands.

By dismantling the button and partition, you gain access to the fittings. By turning the pin, the float is lowered or raised, lowering or raising the fill level accordingly.

Adjusting the float position.

It is not necessary to remove the filling block; you can rotate the pin through the opening.

Vacuum systems from Grohe are equipped with an original mechanism for adjusting the volume of large and small release. The large drain is adjusted with a gate plug.

The gate (blue plate on the left) at the top is the minimum large drain.

Moving the plug to its lowest position. Pressing the big shutter key.

Gate at the bottom - maximum large drain..

Economical drainage is regulated by moving the float along the flask. In the upper position, the minimum amount of liquid flows out, the lower position corresponds to the greatest discharge for the economy mode.

Pressing the economy shutter key, blue float at the bottom.

Common breakdowns and DIY installation repair methods

To troubleshoot problems with the operation of the fittings, it is necessary to provide access to the flush tank. Removing the key to service the toilet installation most often does not require the use of tools.

Step by step process

:

• remove the cover panel, carefully pulling it from the bottom upward towards you;
• unscrew the screws (if any), turn the pusher clamps, pull them out and the mounting frame;
• remove the partition, turn off the water, remove the rocker arm block or pneumatic key block.

Access for dismantling the fill valve and drain mechanism is open. The diagram can be found in the installation instructions. Some manufacturers, for example Grohe and Geberit, place it on the partition of the inspection window.

Water flows continuously

Water continuously flowing into the bowl of a wall-hung toilet is a consequence of deformation of the flush valve elements or contamination. Over time, silicone gaskets and rubber seals lose their elasticity and begin to fit poorly. The tightness is also compromised due to the accidental entry of small debris under the valve.

To eliminate the breakdown, you need to remove the fittings and inspect them. If dirty, rinse thoroughly. A hard, deformed gasket must be replaced.

When there are no problems with the flush mechanism, but water continues to flow into the toilet, it is worth checking the filler fittings. A failed mechanism stops automatically shutting off the water and requires replacement.

The tank fills slowly

Slow water flow may be caused by a clogged inlet hose or fill valve. Dirt, rust, and deposits from deposited mineral salts reduce the diameter of the hole and partially block access.

To solve the problem, it is necessary to remove the flexible line and the filling mechanism, assess their condition, rinse them from deposits or replace them if cleaning does not produce results.

Water does not drain from the tank due to problems with the flush button

Problems with flush keys are often associated with careless use. The button may not work fully or partially if it provides different flush volumes. Water does not flow into the bowl or flows with low pressure and forms a funnel.

On mechanical keys, pushers and lever blocks break. In this case, replacement of the damaged part is required. One of the rocker arms may accidentally jump off the drain valve rods, since they are not fixed, but only picked up. In such a situation, it is enough to simply put it back on.

In pneumatic keys, hoses often fall off. The problem is easy to notice when removing the button. To solve the problem, you need to remove the drain valve, put the tube back on and put the mechanism back in place.

Leak under the bowl

Dirty water near the toilet indicates poor sealing at the connection to the sewer due to a violation of the installation technology. The wall-hung toilet must be removed, the pipe well siliconized and reinstalled.

Seat lift failure

Toilet seats with a silent lowering function are equipped with a micro-lift mechanism, which requires careful use. Sudden, strong pressure on the lid to force it to close will lead to breakage.

The mechanism can use rods with springs or a non-separable system of pistons and cylinders. The fasteners cannot be repaired, but must be replaced entirely.

Removing Geberit tank fittings

Using the Geberit with mechanical control as an example, let's look at the sequence of the disassembly process. First, be sure to turn off the water supply to the bathroom and empty the tank by pressing the release! Then you need to:

• Remove the flush button: lightly press the panel from bottom to top to disengage. Check out the explanatory pictures on the partition. Remove the button.
• Remove the pushers: turn, pull towards you.

Installing a toilet with liquid nails, epoxy resin, silicone

It is possible to install the device on the tile using liquid nails, silicone sealant, or epoxy resin. When using these methods, it is necessary to study all the pros and cons of such an installation.

If you use liquid nails, subsequent dismantling will lead to splitting of the base.

Fixing a toilet with silicone is a common method, but this method does not guarantee that the installation will not move over time. The only advantage of installing on silicone is that subsequent dismantling will take place without damage to the device and tiles.

A safe and reliable mounting method is to glue the toilet to the floor using epoxy resin. But this also has its drawbacks; when dismantling, the tile covering will be damaged.

Installation using all three methods is similar to mounting on cement mortar. The first step is to mark the edges of the leg on the tile. Then degrease the joints, namely the edges of the base and the tiled surface. Apply the mixture to the tiles and the base of the device, then press well and wait until the mixture hardens.

Selection of tools for work

To install any type of installation, the following tools are prepared:

• pen or marker for marking the wall;
• It is better to use a laser level to check the accuracy of horizontal and vertical lines;
• ruler;
• FUM tape, tow for threaded connections;
• sealant with silicone;
• drill, perforator;
• for connecting water pipes and installing a toilet bowl - open-end wrenches.

The installation algorithm for a frame or block installation does not depend on the manufacturer. The technology is the same.

Main reasons

The main causes of toilet leaks are cracks in the plumbing fixture itself. But sometimes the following are mistaken for a toilet leak:

• loose fit of the corrugation;
• leakage of the drain tank, as well as gaskets or connecting cuffs in it;
• condensation on the drain tank.

If the first two reasons can be attributed to technical ones, then the third is a consequence of poor ventilation in the room, and therefore has nothing to do with the problem of toilet leakage as such.

Having determined the true cause of the leak, you should begin to eliminate the malfunction of the plumbing fixture as soon as possible.
