Ideal Standard Dual flush loo - delayed filling

boudzee

Hi, I have an IS dual flush toilet. Recently it has been taking a while to fill. When you push the flush it flushes as normal but takes a while before the water is flowing.

I have taken the cistern lid off and it looks like the pneumatic valve (I think they are called that - its not a ballcock anyway) isn't sinking and activiting the water valve. I have tried WD40 and limescale remover in case there is something preventing it moving.

It DOES eventually fill but we are a busy household and 'waiting' can be a bit problematic :eek:

I have so far steered clear of disassembling the valve.. Any help or tips greatfully received.

The float is catching on something. You need to find out what it is.

Blocked filter or new washer needed on fill valve....check how to service it/diagnose here.

If that were the case then the float would still be sinking as the water level drops which it isn't.
