Hi all,
I've just installed 2 new Fluidmaster 400UK bottom entry fill valves. One of them is the brass shank model (better?) in the upstairs loo and takes 3 minutes (!) to fill the cistern. The other is the 400UK073 plastic shank, downstairs loo (more pressure above it?) and takes 2 minutes to refill.
I'm timing from the point the flush valve washer goes thunk after a flush. The downstairs loo has a brand new Fluidmaster flush valve as well so no water is leaking around the flush valve's washer and into the pan initially, as far as I can tell.
These fill valves are sold as "fast refill" so I wondered what anyone else's expectations would be or experience of these valves? They just seem to give a trickle flow. I read somewhere that 60-90 seconds is a reasonable cistern refill time. 3 minutes is way above that. 2 minutes is better but still feels slow.
There is a cold water header tank in the loft with 22mm pipe feed down to the bathroom upstairs with 15mm down to the bathroom below. There is no flexi connector on the upstairs loo so it's not like that could be restricting flow (it's 15mm copper straight onto the brass shank). I found that a 22mm gate valve was stuck in the half-closed position so replaced that but this made no difference ... still 3 minutes upstairs and 2 minutes downstairs. I've checked all the pipework has a gradient so no air locks can be restricting flow.
I've followed instructions on both valves and undone the cap, run water through to clear any debris.
What should a "fast refill" time be for these valves?
Thanks!
