whistling pipes

[beaniebrain]

Hi Everyone,

Two of our toilets (on the same stack) have started making a loud whistling sound when flushed. The downstairs toilet started doing it first and now the upstairs does also. They only do it when flushed. Both toilets are less than a year old. The house was built in 1986.
Please tell me what's wrong and if we can fix it ourselves or need a plumber.

Thank you!

Alice

obviously noise from when they are filling if you live in a hard water area it could be the down to scale build up in the washers on the ballvalve

It really does help to diagnose problems if the poster takes the trouble to think about what they are saying.

In this case the toilets do NOT make a whistling noise WHEN they are flushed. They are making the noise AFTER flushing while the cistern is refilling.

I am not sure why DIA suggests replacing a plastic ball with a copper one. I would go for the cheaper option of replacing the whole float valve reusing a plastic ball.

In a few cases a mains fed float valve is wrongly configured as a low pressure valve and becomes noisy.
