Stop the toilet from running: the definitive solution explained by an expert plumber.

Introduction

One of the most common and annoying problems in the home is a constantly leaking toilet. Not only does it increase your utility bill, it can also damage the internal parts of the cistern and cause environmental waste.
A plumber with years of experience has revealed a simple, effective, and affordable method that allows you to solve the problem without expensive repairs.

Ingredients (what you need)

A Phillips or flat-head screwdriver (depends on the cassette model)

A small wrench

A pair of latex gloves

A dry cloth

(Optional) a new float or a new drain gasket

Instructions (practical steps)

Turn off the water tap that supplies the toilet cistern.

Empty the cistern by flushing it.

Remove the cassette cover carefully.

Check the float: if it is worn, bent or stuck, adjust the rod or replace it.

Check the drain gasket: if you notice cracks or limescale residue, replace it with a new one.

Clean the components with a dry cloth and, if necessary, remove limescale.

Reassemble the cistern, turn the water tap back on and test it: the flow should stop completely.

Serving and Storage Tips (Good Practices)

Check your toilet cistern at least once a year.

Do not use aggressive chemicals that damage the seals.

If the leak occurs too often, consider replacing the entire flush mechanism.

Variants (other effective methods)

Quick method: If the problem is minor, simply adjust the float by bending the rod slightly.

Universal replacement method: There are inexpensive universal kits that allow you to replace the entire mechanism without calling a plumber.

“Anti-waste” method: install a double-flush cistern to reduce water consumption.

Generally between 15 and 30 euros, depending on the quality.

3. Can I do it all myself or do I need a plumber?

On average, 20–40 minutes, depending on the complexity of the model.
