Water level in the toilet bowl

Oct 09, 2006 16 Replies

The plumber recently installed two toilets in my house which, after the



were installed, I noticed that there was a rim on the toilet bowl whi seems to indicate where the water level should be. I mentioned this t the plumber and asked if there was a way of adjusting the level of th water and he said that there wasn't. He siad that the level of th water is dictated by the height of the outlet at the back of th toilet. I myself find this hard to believe because the rim on th toilet bowl is there for a reason, plus it always looks ....wrong o something.



Any advice on how the level can be adjusted would be greatl appreciated

What the plumber said sounds right to me, if the bog's level I cant see theres owt you can do ( apart from build a little dam !!)

Your plumber is right, and you are wrong.

It can't. It's set by the height of the back of the outfall. Provided it's level, that's where the water sits. Any ridge is purely there to irritate the sensitive.

The level of water in the bowl is set by the shape of the S bend at the back, by the manufacturer. Adjusting the shape of the S bend is neither practical nor advisable. Do nothing, the Manufacturer manufactures to some standard, BS, or ISO which I have not looked up.

The plumber's right - take a look at the following pic to understand how the s-bend works, and how the level can't be any different:

What others have said is true but to allay your fears, slowly pour a kettle full of water into the pan, down the side. The level should basically remain the same and is set by the level of the outlet. Report back if it rises by more than 10mm.

I have noticed that if the upstairs WC hasn't been used for a while (some hours) and a weather system comes over, the water level in the pan drops. Not something you can adjust yourself, but a possible contributing factor

well, you can't adjust it . I have noticed though that on windy days gusts of wind come down the SVP and cause the water to slosh about which can cause the level to drop a bit. Interesting topic BTW

1) Completely seal the room so it's airtight. You'll probably need an airlock instead of a door. 2) Install an adjustable vacuum pump to reduce the pressure in the room.

Atmospheric pressure in the soil pipe will push water around the U bend to the level you desire. Then set the vacuum to that pressure. If it's only an inch or so out yu should be able to breath OK at the reduced pressure - it will be no worse than La Paz for example.

Thanks for all the replies I'll have to go eat something now tha

resembles humble pie.....

But the soil pipe is full of *air*, so all you will get is big burps of foul smelling air. ;-)

You might like to try one of these...

Here's a (probably) more detailed description:

I wouldn't fancy using that snorkel idea if the soil stack terminates in a roof space with an air admittance valve on top, we did just this with our side extension so we didn't need to faff about sealing the pipe where it would have come through the extension roof.

No - but I'd spotted it some time ago.
