My toilet won’t stop running
Assistant: I'll do all I can to help. How long have you been dealing with this?
Customer: I noticed it the other day and it would do it for around 15 minutes after flushing, but now it’s doing it constantly
Assistant: Do you plan on doing the work yourself?
Customer: Yeah
Assistant: Anything else we should know to help you best?
Customer: It’s a push button toilet if that helps

Is it constantly running, or constantly overflowing?

Customer: replied 2 years ago.
It’s constantly running from the cistern into the bowl. The float is up as far as it goes and adjusting it hasn’t stopped the water - currently turned the water off. The seal for the flush is fine I checked that last night and there is no leak.

When you look inside the cistern, you can see the water level is over the top of the overflow pipe into the cistern?

it is

Ok, that means the balltap wants a new washer.

If you are able to rewasher it yourself then it will cure your problem.

How would I do that

Looking at the cistern, it will be the blue cap that unscrews.

You will need to turn off the water to the cistern.

Remove the blue cap and disassemble balltap

Remove old washer

Refit new washer (you wont know which type until you have the old one out)

Refit cap and reassemble balltap

Turn on water and test

Fill cistern

Adjust water level.

All done ;-)

The blue bit is the floater that moves up and down, so which cap is it I unscrew?

The white one next to it that is attached to the float, it unscrews anticlockwise.

Be sure to hold the rest of the balltap to stop it spinning
