Toilet cistern

[chfriend]

my downstairs cistern makes a noise like a ferry boat foghorn when it is flushed I have just recently put a brand new complete valve assembly in (from Taskers) a local DIY shop be me and that is making the same noise the wifes on me back HELP

is it the ferry on the mersey ?

what the cistern supplied by mains water or tank ?

 

[chfriend]

yes thats just what it sounds like and its mains fed

useally its the diaphragm faulty they do that when they get old.
but a new never seen it happen.

did you fit any restrictors in the bottom before connecting the water pipe to it ?
is it all tight up top ?

 

[chfriend]

not sure what you mean where would the restrictors be

When you say 'valve', have you replaved the float valve or flush valve?

I have a nasty Opella Variflush drop valve and a bottom entry fill valve of some sort and it makes the same noise when flushed, I dont know if its the fill valve through or flush valve though.

Replace with Fluidmasters.

 

[chfriend]

its the flush valve

 

[seco services]

when you fit the fill valve into the cistern and do the plastic nut up
before you connect the water pipe you can fit flow restrictors in the inlet to the fill valve depending on your mains pressure.
they come with the valve.

 

[chfriend]

is that the two holes in the main body with the plastic strip on the side

 

[seco services]

what did you fit a flush or fill valve ?

 

[chfriend]

FLUSH

 

[seco services]

think you want to be looking at the fill valve thats the one that useally sound like a fog horn.

if you hold the fill valve up or stop the water filling the cistern then flush the loo the noise probably won't happen.
