Toilet problem and it's spreading.. help please!

essexsi_2

Good morning all.

I have lived for 2yrs in a 4yr old new build flat.

As I am on my own I have used the mostly the ensuite toilet. About 6 months ago the toilet, that has a built in cistern, started to make reverberating noises on flushing and filling up. This built up until the noise stayed all the time!! The toilets are fed with plastic pipe off the mains.

I then had a leak in the bathroom from the cistern. This caused water damage that has recently been repaired. The cistern during this time was isolated and so the noise stopped. During the repairs I then used the 2nd bathroom.

The plumber ,who fixed the water damage, adjusted the float valve and changed the high pressure inlet fitting to a low pressure one. He also reduced the flow to the cistern on the isolation valve. This appeared to work initially, now the noise is back, worse it is now happening in the other toilet!!

Whats more I can also hear it throughout the block when other people flush there toilets!

Any solutions come to mind? Is it a common problem in new builds, mains fed cisterns etc.

Sorry for the long post and thanks for any help or advice.

All the best Si

Hi

Why the plumber changed the fitting to low pressure is beyond me. It should be high pressure so will need changing back.
Not sure what type of ballvalve you have but I would recommend a Torbec type.
Noisy ballvalves (assuming that any noise has developed over a short space of time )is usually the washer or blocked filter.
I would say get the plumber back ,but he doesn't seem to know what he's doing (from your description) so find someone else.

Hi Canucklehead,

Thank you for your reply. As it is now spreading throughout the block I assume that they may have used inferior ie cheap fittings when building the place. Could this be correct?

Should I supply these Torbeck valves and then get the plumber to come back and fit them?

Thanks for your time. Cheers Si

You dont have to supply the torbeck valve, you can inform the plumber to supply them, either bottom inlet or side inlet.
But i wouldn't use the same plumber, as stated above CHead, he should have not changed the valve seating for a low pressure 1 if you are on mains pressure, and turning the isolating valve down will only increase the problem.

I would asume that with it being a new build you will have you own main?
And pressure reducing valve could be fitted to the incoming main.

Hi plumb1 thanks for your reply.

I am on the 3rd floor of the building in a flat so I am not too sure about my own main.

The Torbeck valves will solve the problem then, or is it a case of addressing the other points such as pressure reducing valve etc.

Thanks for your time and replies. Si
