bidet waste pipe 32 or 40mm? someone help please

[WilfredoLimb]

Hi,

As title says, I was going to connect my bidet with a 32mm trap and 32mm pipe which connects to a 32mm pipe boss on the pan connector.

Is this a sound plan?

I was thinking as its Bidet waste maybe use 40mm? But then again do you get boss pan connectors that are 40mm?

Someone advise please,

Thanks,

Wil

Treated as a washbasin sink - 32mm, but not to the pan connector since this is likely to induce a loss in trap seal of the bidet.

hi, thanks, what does a that mean exactly?

should I try to connect directly to the soil pipe further down the pipe?

When you flush the toilet, the exchange/rush of water through the pan connector will cause a vacuum to be formed which will suck air from your proposed 32mm waste pipe, which may pull water from the bidet trap. Hey presto, ponginess all round.

Ideally, you should boss onto the stack outside, but if this is not possible then you need to install an air admittance valve somewhere along the 32mm pipe (I think this has to be within 30mm of the trap, but someone on here will no doubt correct me if I'm in error). These are not expensive and can be installed in-line and not be obtrusive. Not sure what space is available for the trap for the bidet as it may come with one as part of the kit, but you may be able to get one which has the admittance valve inbuilt into it.

I see, thanks alot i'll look into that.
But 32mm is big another for bidet waste then?

Cheers,

Oh, one more thing, I take it the air admittance valve has to be between pan connector and bidet?

i was going to extend pipe past bidet for a rod eye access, could I put it there?

Thanks!

Sorry - I forgot to reinforce your point that you should boss into the pipe further along the run. The admittance valve goes on this run of 32mm pipe if you can't fond a replacement trap with the AAV integral to it.

In any case, not sure you could get a boss strap for a pan connector, nor whether the adhesive used would work on the type of plastic.

was goin to put bidet waste to this (isn't this what this connector is made for?)

If I have a AAV between bidet and this connection, would that be ok?

Thanks again mate

why don't you just fit a trap on the bidet with an aav

 

[WilfredoLimb]

Looks like it - must admit never seen one. Then again, never looked for one. How high up is the waste from the bidet? You sure you're not going to have the 32mm pipe running uphill to the pan connector boss, cos those fittings look like they need to be installed with the boss at the top?
