Advice on leaking waste pipe connector

[kahyang]

Hi,

Really hoping someone could advice me on a leak issue I'm having.

We have a macerator type set up for our ensuite, that joins to the main soil pipe in the loft. The connector where the pipe from macerator meets the main soil pipe is not water tight, and therefore excess water is flowing out. I have a video here (hopefully it works).

If I apply pressure to the connector against the soil pipe, the leaking stops so clearly a watertight issue. Any idea how I could tighten this connection? Would silicone around the connector work? Or would this require something more major?

Thank you...

Where’s is leaking from? Where the boss plate attaches to the stack? I’m assuming so, as of it were one of the compression nuts, you’d have tighten it.

If it is the boss plate, you ideally need to redo it. Please don’t bandaid it with silicone.

It’s a mechanical boss like this. They come with a fixing tool. You maybe able to tighten it without the tool but you’d have to disconnect the macerater discharge pipe to have a look. I’ve not used this one to be able to advise if you can tighten it without the tool.

Ideally you want to ditch the mechanical boss and get a solvent weld one.
