Rated 5 out of 5 by from bestthereis I have fitted a dozen or so of these now and in my mind the best fill valve about. nice brass thread means no worries about cross threading very quite in opearation fills quicker and totally reliable. dont waste your time with cheeper plastic types this is a fit and forget part well worth the few extra pennies

Rated 4 out of 5 by from Good product Bought to replace an older simillar valve that had started to fail. The Fluidmaster Pro was a straightforward swap and is an improvement over the old valve as it is more easily adjusted for the fill level. Would buy again.

replacement seal

Where can I get a rubber replacement seal for this that seals the bottom of the shank inside the cistern
Asked by: gagt

Does this have a refill tube?

I have a Fluidmaster 400A bottom fill valve in a 3 year old toilet. The refill tube port is closed off (as supplied) and I am not sure if it should be. OTOH there is no overflow tube in the cistern to direct it down (overflow is internal via the siphon).

What is the lowest pressure that this will work at

Asked by: Dave6B
Avoid this valve if pressure is below 0.5 bar. It wont shut off and run constantly

Difference between the standard one ?

What's the difference between the Pro version with brass shank and the standard version with brass shank ?
Asked by: Anygasman
According to the Fluidmaster web-site, the internal construction of the shank is specially design to reduce noise from water hammer.
