Why Fix a Leaky Toilet Quickly?

A leaking toilet wastes water 24/7, can increase your water bill, and over time may cause damp issues or staining.
In North Devon, where many homes rely on private water supplies, fixing leaks quickly is also about conserving resources.

Step-by-Step Toilet Repair

Step 1 – Identify the leaking toilet

Look for a constant trickle of water into the bowl. This is often most visible just after flushing.

Step 2 – Isolate the water supply and remove the cistern lid

Turn off the isolation valve located near the toilet. Then remove the cistern lid carefully and set it aside.

Step 3 – Remove the flush valve

Twist the flush valve anti-clockwise and lift it up to access the washer.

Step 4 – Confirm the replacement washer

Before fitting, ensure your new flush valve washer matches the old one exactly in size and design.

Step 5 – Remove the locking tab

The locking tab holds the washer in place. Remove it to free the old washer.

Step 6 – Check for limescale build-up

In hard water areas like High Bickington, limescale is a common problem. Clean the flush valve seat thoroughly so the washer can seal properly.

Step 7 – Fit the new flush valve washer

Install a high-quality washer to restore the seal.

Step 8 – Fit the new locking tab

Replace the locking tab to hold the washer firmly in place.

Step 9 – Refit the flush valve

Reverse the removal steps, making sure the valve sits snugly and is properly aligned.

Step 10 – Refill and test

Turn the water supply back on, let the cistern fill, and flush to test. The leak should now be fixed.
