How we perform professional toilet cistern repairs in Madrid
Fixing a leaking or non-filling toilet cistern starts by diagnosing whether the fault lies in the fill valve (float) or the flush mechanism (flush valve). We close the shut-off angle valve of the toilet and empty the tank. If water overflows through the overflow tube, the problem is usually that the float does not cut off the water flow due to lime scaling or being miscalibrated, making it necessary to clean the valve or replace the float valve entirely.
If, on the contrary, water filters continuously into the toilet bowl without the tank filling up completely, the rubber gasket at the base of the flush valve is deformed or blocked by accumulated lime. In this case, we dismantle the flush valve and replace the bottom sealing gasket with a new silicone or rubber one. If the general mechanism is badly deteriorated, we recommend replacing the complete cistern kit (button, flush valve, and float) to avoid future breakdowns and ensure proper water savings with a 3 and 6-liter dual flush.
