Gerberit soil pipe connection problem.

[CoxHQ]

Hello,

I'm trying to find the right way of connecting up the Gerberit wall hung toilet frame to the existing soil pipe.

The existing 110mm soil pipe is low by about 100mm (it needs to connect to the frame where the yellow circle is) and it's angled up by 15-20 degrees. I wondered about using a flexi but there's not much room between the frame and the wall - 180mm.

Does anyone have any suggestions please?

Thanks!

If you're very lucky a McAlpine WC-CON7A might help. But the real answer is to modify the stack and come through the wall at the correct height and and angle.

Thank you for the reply. I've just had a look at the WC-CON7A. It looks like it would level it out but I'd still be at the wrong height. Do you think I could get a flexi something in there? How much flex do they have?

I’ve never had to use one and don’t know how good they are, but have you tried one of these?

Not suitable at all for what you have.
Open the wall up and fit 2x45 degree bends, that’ll do it properly.

I'm afraid you've already been given the right way by Polesapart, very doubtful anything else will work. There's unlikely to be enough room to get a flexi in, if you did, it would probably be under so much strain it would either keep falling back out the soil pipe, or split quite quickly. Using an adjustable bend would mean cutting the wall out to accommodate it, and by the time you've done that, (even if it will line up), you may as well have realigned the soil pipe in the first place.


Only solution there is to realign the soil pipe through the wall, I suspect trying to cobble together anything else is only going to give you a headache, before, during and afterwards.....

Thanks for your advice chaps. I hadn't considered taking some of the wall out and connecting further back. I'll see if it's a few easy bricks and if not, you're right - do it properly.
