Got to help a relly out -
Couple of questions:
Current one is sealed in with some sort of gunk on the bottom entry hole. After I've scraped that off, what's a recommended sealant to use?
Fernox LS-X or something with a bit more "stick" like Geocell TheWorks (MS polymer I think, stickier than silicone) - or something else.
The other thing - do all bottom entry valves have the same threaded section length? The pipe runs straight in with a tap connector on the isolator valve so there is no "give" for slight differences.
Sorry to sound thick - only used side entry valves before.
I'm thinking of a
as I have one at home and love it. Brass threads and a good clean shutoff. Not sure yet if there's room, as the fill entry is on the same side a sthe flush handle so it's a bit crowded in there!
