Leaking Terrain Soil Stack Boss

[TwistedPear]

Hi All,

I have a leaking boss on my soil stack. The boss is made by Terrain.

The curved plate that sits against the vertical pipe seems to have come away slightly, hence the leak.

Would anyone know if the boss can be reseated to fix the leak? I have no idea how the seal works inside the boss, hence the question.

I've also added a picture of a second boss outside my house that isn't leaking as it's still firmly against the soil pipe.

Many thanks in advance,

They look like what we're know as terrain patch bosses.
Simply solvent welded on used to use a couple of big jubilee clips
to hold them till cement set.
May be able to clean it up enough to re solvent weld who knows?
Terrain is no longer available bought out by polypipe who stopped producing it several years ago.
Maybe try taking apart take further pics and report back.

As above, but depending on the size of the hole in the stack you could try something like this, https://www.screwfix.com/p/mcalpine-mechanical-pipe-boss-connector-black-40mm/55722
