Rated 5 out of 5 by from Excellent replacement ball val Excellent product. Very easy to install and adjust. Comes with brass fitting on base so reduces the chance of cross threading the tap connector.

Rated 5 out of 5 by from Excellent product Old inlet valve would'nt shut off so bought this as a replacement, brother in law fitted it in 10 mins. No more over running toilet yea finger crossed it lasts longer than the last one.

Rated 5 out of 5 by from King of bottom fill valves After a bit of browsing I decided to buy this valve to replace an ageing ball arm operated valve in our en-suite toilet. Certainly not the cheapest, but you get what you pay for, and this looks to be a well designed and we'll made valve that should last years. Simple to fit following the good instructions that are supplied. There are videos on the net for fitting this valve if you prefer to watch rather than read. It fills the cistern quickly and is quieter than the old one as it fills from the bottom of the valve body. Very happy with this. Good service as well from Screwfix.

Rated 3 out of 5 by from Could be better Should have been an easy fit, and it was, 5 minutes to do but the new unit had a faulty seal and kept filling and wouldn't shut off! Had to salvage the seal off an old unit to make it work. Also not the quickest to fill either. In theory a good unit and mine was probably just a rogue one but it c-cked up what should have been a quick and simple job.

Why won't the cistern stop filling when it is full? (Nb low pressure system)

Have bought 2 of these. Neither stop filling when the cistern is full resulting in permanent overflow leak. No matter what I do, I cannot (even manually) stop water coming in.

How wide and deep is this at its widest/deepest point?

My inlet valve now has a ball float on an arm ; this float is well clear of the siphon . If this "float" is deeper than 50mm. it will not fit alongside the siphon.
Asked by: salesiano

what is the most likely cause of a leak?

Asked by: itsonlyayearold
This depends where the leak is situated; is there water entering the WC pan, or is there water leaking out of the cistern? It may be worth contacting the Fluidmaster UK support team for a more detailed diagnosis explanation, +44(0)1432 357331.
