Title: Toilet is running, until the tap is used...
Post by PM on Sep 16^th, 2015, 1:36pm

Hi there,

First time poster, so please be kind. The problem is that after flushing my toilet , it does not stop filling, so it runs. This is then where it gets strange. If you run the bathroom sink tap on full (located next to the toilet) the toilet stops running immediately. Then when you next flush, the process starts again. Also, the float valve does detect that the water level should stop, as the arm and float move to stop it. But the water keeps running.

I need to know whether this is perhaps a water pressure problem (I.e. Too much), or whether my toilet float valve is faulty. Or maybe just a simple washer problem. Or something else?

A bit of info: the toilet is less than two years old. The problem has been happening for about 6 months (I've now decided that enough is enough). I have already adjusted the float so that it is supposed to stop at a lower water level.

Many thanks

Phil.

Hi Phil do you want the normal or nasty version ;D ;D

Check the pan for a continuing discharge of water after the flush.

What the normal problem could be is the flush valve isn't seating properly maybe an piece of grit, they are usually quite simple to unclip (twist) clean and replace.

The other maybe high pressure and the restrictor hasn't been fitted.

I would go with the first option first

Thanks thescruff, I will try and clean the valve. See if that fixes it.

Cheers,

Phil.

Check that water is running into the pan first. the flush valve should split into two bits quite simply, so with the water off you'll see the washer
