Loo overflowing into pan. Help solving please?

Mrs_Arcanum

From research elsewhere I have worked out the overflow in my loo is running into the pan (at the front). I have one of those push button systems (no Ball & arm) rather than a flap or chain so need help identifying which washer needs replacing. The float arm is on the left & has an adjuster over the float to sort out the height of water. In the middle is a big round tube with two buttons on the top which are what makes it flush when pressed. I am also getting whistling noises & the the cistern filling for a few seconds at random times.

Thankfully not on a water meter but still a problem needing a solution.

Cheers in advance for any help.

The whistling is due to the pressure of water when the cistern is filling up.

It sounds like you have a newer style cistern with an integrated overflow. The cistern will overflow if the water filling it doesn't stop. Do you know if you have the correct reducer fitted? (should be red if the toilet is fed from mains water and white if it is tank fed)

No Idea on the reducer as this was attached to the old pipework. This has only recently become an issue as was fine for 18 months.

Does the toilet constantly fill up causing it to overflow?

posting a piccy would help us all to identify it.
either it needs a new inlet valve washer/seal. or the float needs adjusting.

The valve you describe in Post #1 is your flush valve rather than your fill valve. Its the fill valve that's causing the problem either by having a naff diaphragm or the float needs adjusting both as Ormus has said.

There are a number of different types on the market and so it would be useful, as has been mentioned, to have a picture in order to tell you exactly what you need to do. What is certain is that you won't have a red or white "reducer". These are the high and low pressure cones that are found in the older ballvalve type of fill valve. What you may have (but the installer should have left it in place or removed it depending) is a flow restrictor normally found in the inlet to the valve itself.

The whistling noise suggests the diaphragm to me. Replacement is simple but, once again, need to know what type.

HTH for the time being.

Could also be the flush mechanism letting by.... just to complicate matters!

Could be indeed but most unlikely IMHO that both fail at the same time - unless they are both Siamp of course. Sorry but I just don't like 'em. On balance at present my feeling is that is the fill valve.

Its either the plastic washer at the bottom of the flush cartridge or the washer in the fill valve..

OR someone has been playing with it & the float has been adjusted incorrectly

Not the best picture as using phone camera. Hopefully you get the idea.

Thanks again.

If the float is adjusted anywhere but where it is (fully screwed in) I get water appearing on the floor at the front of the loo pan.

If its actually on the floor it is the doughnut washer thats faulty. A big washer the size of your fist that goes between the toilet and cistern that sits on top. Or the water on the floor is condensation caused by the continuous flow of cold water into the cistern OR both.


You need to firmly establish why the water is going into the pan. Are you sure its down the overflow? If so the fill valve needs adjusting or it needs a new washer etc.

If its not the overflow it is most certainly the flush cartridge washer or the whole cartridge that needs sorting
