Cistern Problem...

Hi All,

This is possibly an easy fix!

Dual Flush level cistern - bought from B&Q.

When Loo is flushed, cistern is filling up very slowly and is making a hissing noise.
On initial investigation, I loosened the fixing where the hissing was coming from and it filled fine.
That was about a week ago and now it has done it again and my initial fix has not worked.

Any ideas?????

Thanks

Some inlet valves have a filter which may get clogged after pipework is disturbed. Try disnanting valve and cleaning it.
