Toilet Pipework

[Inthedarkcustomer]

hi

We have a new downstairs toilet fitted, it is connected to a new pipe under dining room running directly to main drain. Does anyone know what the grey pipe work is and why do we need it? I've never seen this in a downstairs lol before!

Thanks

WTF in 20 + years plumbing I've never seen a basin on top of a toilet .

It is an air admittance valve.....needed to prevent a vacuum when you flush (I think!). Ugly install, but its probably needed (sounds like your WC is in the middle of the house), though I'd have had it boxed it.


Cool toilet.

Have you not seen those AGAS?
I've fitted a couple of them and they're not bad given the right circumstances - quite a clever idea until you consider what might go down the plug hole to foul up the cistern

I have to admit I've used a basin as a toilet

It looks as though a commercial fitter has worked on the installation as this is the sort of setup you find in restaurants and offices. As Wabbit says, its an air admittance valve to stop the water trap in the basin from being sucked out when the toilet is flushed, but I think that the basin has already been designed to handle this problem, so I don't think the AAV (and all the excessive pipework) is necessary - unless by some chance, there's something else going on in the property

I've seen the toilet in B&Q, but they know sweet FA about it, but they should be able to point you in the direction of the manufacturers.
