Hi all. The syphon failed, so I fitted a new Fluidmaster flush valve with side handle which is very good.
I took advantage of pulling the cistern apart to fit a new bottom entry fill valve, namely a Skylo type. The original took forever to fill. I won't bore you with the details but I want a reasonably quick fill. The new fill valve must shut off too quickly as I get severe water hammer now when the valve shuts. I have reduced the main stopcock to reduce flow, and I have partially closed the cistern isolation valve. I now detect a little hammer, but the general house flows are now too low. So I really want to open the stopcock and isolator and attack this hammer another way.
Can somebody please advise what I can do? Can I fit an alternative fill valve that will not cause hammer. It just needs a valve that will shut more slowly.
Incidentally, just after the main stopcock is an inclined pressure reduction vale set to 3 bar, made by Caleffi.
Can I reduce the pressure with this valve and cure the hammer, whilst maintaining a reasonable flow?
Thanks for any help.
Nick
