Hi there.

I had/have a slow filling toilet after flushing.

Saw this video on youtube which is a model similar to mine:

So went to the hardware shop and bought the only rubber valve they had in the hope it would fit mine. Unfortunately the valve didnt fit so I fitted the broken valve with the logic being at least the toilet still fills (even if its slow filling) until i can go to bandq.

However after placing the old rubber valve back on. When i flush the toilet it overfills. NOT EVEN LIFTING THE FLOAT ARM STOPS THE WATER FRO COMING INTO THE CISTERN!!

Any ideas what I have done wrong?? Thanks for your time

Well, the answer may be in the question. You bought the wrong sized replacement - and it does say in the vid that they aren't universal...

There's a possibility that it isn't aligned correctly si double check instalation but I'd take the broken one to a different hardware store and get the right piece.

Otherwise you'll need buy a whole new cistern mechanism which will isn't much more than £20 but more of a job than this little repair.

Should the float arm still work no matter what valve I put in?

Yes, the float should lift a bit (Depending on resistance of the new valve) but as you said



If you fit the wrong part to something (as you have done) then what ever it is fitted to will not work, and so will any other parts that rely on this wrong parts function will also fail to work properly.

In Plain English: You have wrong part, you need right part for all to be well.
