110mm / 40mm soil adaptor not deep enough?

[smallsteve1]

With reference to the attached picture, if the adaptor is pushed all the way down then it is around 15mm below the top of the pipe, slightly exposing the rubber seal. Of course i can lift the adaptor up so that it is level, but wonder if this movement is an issue? TIA

I'd pull it up a bit.

Thanks for your input. The other type of adapter unfortunately won’t work as the shower tray and pipework is just slightly offset from the 110 mm pipe.

I'd be tempted to pull it up a little and then wind a couple of short screws in either side (if the shower waste goes in at 6 o'clock position, wind in at 9 and 3 o'clock) right though the outer pipe and the adapter, just below the seal. The screws will be self sealing and will be out of the way of any hair getting hooked on them but will keep the adapter in place. You wouldn't want that seal to work it's way out to being a hole that allows sewer air in under the tray (unless you have permanent access to the tray underside and can repair at any time.. but even then, fix it once)

THe adapter is in a socket - it's sized to go into a pipe - so a short piece of pipe with chamfered end an a smear of silicone grease, fitted in the socket - then the adapter into that

Thanks for your input. Just so I understand, are you talking about (say) a 20 mm deep piece of 110 mm pipe placed first into the soil pipe and then the pictured adapter going in and sitting on top of it?

Pull the adaptor out and post up a picture of it side on

it’s a bog-standard solvent weld 110 to 50 / 40mm adaptor, as per stock picture:

If you're saying it's the same thickness all the way down it's different to what Nige is envisaging. Nige is saying the adapter is slimmer underneath than the ring you can see touching your pipe's rubber seal, so you find a very short section of 110mm soil to push the adapter into and then push the short 110 into your pipe socket, like this doodled-on drawing of a McAlpine waste adaptor:

Black- adapter
Red- a short bit of soil pipe
Blue- your grey pipe with the rubber seal

The length you cut the red pipe in this drawing determines the height at which the adaptor sits

Ah right, think they are 100mm adapters for clay pipes. Mine is 110 mm and just a bit short for the depth of pipe receptacle. I suspect it is a non-issue, but I would rather ask daft questions then find out the hardware once it is all plumbed in and I can’t get to it!
