Rated 5 out of 5 by from Amazing Value Bought one of these to replace the one in the loft for the cold tanks. The identical one already fitted had deteriorated and the washer and the high pressure plastic nozzle were damaged and leaking. I initially considered overhauling the existing valve but when a saw the price of a complete new valve I bought one and replaced the whole thing in half the time it would have taken me otherwise.

Rated 5 out of 5 by from New Float Valve - did the job Bought this to replace a calcified old Part 1 float valve system in the cold water tank in the loft. Had to do some research in Google as to what the difference is between Part 1 (the old kit they used to fit) and Part 2 (the new anti flow back that all new builds are fitted with). Easy ordering and collection - the usual Screwfix efficiency and professionalism. Part fitted easily. Job done.

Rated 5 out of 5 by from Flomasta ball valve Needed a ball valve urgently. The important thing is that Screwfix had it in stock and the collection notification came through within 10 minutes of ordering. Staff at Yeovil efficient and helpful.

Do I need additional washers for this?

Looking to install this for an attic cold water tank. Are any additional washers needed that dont come with the part?
Asked by: bunit
You’ll most probably need a new fibre washer for the tap connection on the inlet. The old ones become brittle over time

Is this valve suitable for use in a hot water cylinder expansion tank where the water is very hot?

Asked by: Chanter

Hi. Trying to replace old ball valve with this part 2 valve. But the washer in the adjoining isolating valve has perished.

When I attach the part 2 float valve to the isolating valve on the water supply to the header tank, I get a drip, also the washer in the isolating valve has perished. What's the correct washer for the isolating valve please?
Asked by: ScottBytheway
Hello ScottBytheway, A 15mm o ring should be sufficient as these are normally used inplace of a washer. Thank you for using Q&A
