Soil Stack Question!

[skwdenyer]

Hi. One for the more experienced soil-and-waste people on here. Does such a product exist as a (to use my term) double stacked soil branch (110mm)?

I need to take 2 soil pipes through a wall and join them into the soil stack. There is not enough vertical separation to allow for 2 separate equal 90 degree branches stacked one above each other. There is not enough horizontal space to allow for an offset bend to create the vertical separation for such an arrangement. There is no enough space to merge the 2 branches within the building before coming out to a single stack connection.

I've mocked-up the item I'd ideally need, but I can't yet find a supplier for such a thing. Can anyone suggest somewhere I could try?



Thanks!

What is the length of horizontal run outside of the building before the stack ?

Out of interest , what level above ground is this ?

I'd try cutting the fittings down and gluing the socket. 20mm overlap on a glued joint should see you OK.

You can always get two of the T's and get a plastic specialist to cut and weld them to the design you require.

I 'modified' a rainwater downpipe with a certain epoxy resin to connect a waterbutt, and it was fine until I dismantled it 15 years later.

Use solvent cement, please......

Thank you for all of those suggestions. In honesty, it hadn't really dawned on me to cut one of the fittings down. The main problem is that the entries are generally swept, which limits how much scope there is for such modification. If I can get hold of an unswept T (I've found one at an online seller's site now) then I can probably make that work. Thanks again.
