How to solve flushing problems

Any toilet leak must be repaired quickly because it is both unpleasant and very expensive. Something has to be done!

How to solve flushing problems: flushing

Sooner or later, the toilet flushes out. It is first a trickle of water that flows into the bowl of the toilet, identifiable with the trace of rebel limestone that leaves on the enamel. Then the net grows and you can hear clearly the flush valve that "gurgles". Finally, the flush is triggered by itself, at any time of day and night.

How does a toilet flush?

How does a toilet flush?

Whatever its type, a flush includes three elements more or less elaborate and reliable depending on the model:
- a valve opening and closing automatically depending on the need for filling;
- a float, controlling the opening of the tap when the water level drops (this is the case, obviously when it empties);
- a mechanism (from the simple bell to the sophisticated silent mechanism) that releases the water when the control button is pressed.

Types of flushing faults

Types of flushing faults

The permanent operation of the flush valve can have three distinct causes:
- leakage of the flushing mechanism itself, which allows water to flow continuously (the float then controls the opening of the valve which remains open continuously);
- a leak at the tap valve seal that lets the water run continuously (the flush fills beyond the maximum level, the water flows into the bowl through the overflow, the flush goes up to 'to go off alone);
- A disturbance of the float (or its drilling if it is hollow) which disrupts the operation of the valve.

Examination and diagnosis

Examination and diagnosis

Close the small stopcock which is outside the tank of the hunt, just at the level of the water inlet:
- if the water is still flowing in the bowl, it is the mechanism that is involved. It is sometimes enough to change the base gasket, at the bottom of the tank, but it is often necessary to replace the whole mechanism (the latter being sealed is irreparable);
- If the water stops flowing, it is either the tap or the float that is involved.

Intervention on food

Remove the tank lid (models attached to the toilet bowl) after having, if necessary, unscrewed the control knob:
- make sure that the float is not unhooked or free on its stem (some mechanisms integrate the float, which is not apparent); adjust it if necessary by adjusting its position according to the maximum filling level of the tank;
- If the faucet leaks, it is almost impossible to fix it, most current models being diaphragm.
You can try to disassemble (with two flat keys) and replace it (take it to buy the same).
It also happens that it is simply an accumulation of limestone which disturbs the mechanism of the tap. Disassembly makes it possible to soak it in a solution of hydrochloric acid substitute and restore it to its full effectiveness.
