Noisy (Torbeck valve) cistern

the LP one in there or none at all?
Had a looksee, and can't see anything in there so I guess I must have
bought an LP version. Sounds like it's worth investing 6 GBP in a new
valve, anyway!
Ah. If there's nothing in there, then on a decent mains supply you
will certainly get thumping as the valve closes. It might even
vibrate. I have a fairly peewilly supply and still can't get away
with no insert at all - it has the LP one fitted for the loft tank. I
added a second valve and improved the supply though.
Just to be clear, the valves are normally supplied with both
restrictors - often the mains one is fitted - I imagine because that's
the fail safe; i.e. tank fills slowly.
- If there is banging from the pipes, this is usually because they
aren't supported properly,
But unfortunately they are very inaccessible where they bang, too:
behind a finished plasterboard wall. It's only an issue if I let the
cistern fill too quickly though.
That's a shame. You might be lucky after fitting a new valve with
restrictor. Don't forget to put on and finger tighten the tap
connector nut first then the backnut onto the cistern. Less risk of
crossthreading.
- Replacing the toilet is unlikely to solve a valve problem, but you know that.
I do indeed, but SWMBO doesn't: or if she does believe me she reckons
that the threat of pitching up with a new loo will spur me into action.
And whaddyaknow...
Seems to have done :-)
Of course if she did and it still made a lot of noise, you'd be in even
more trouble and she'd want to "get a man in"
I hope you have a lampost in the garden to mark your territory accordingly :-)
