Advice / info needed for soil pipe.

[Caps]

Hope someone may be able to help as i'm getting conflicting 'advice'

Does anyone know where i can get 2 x caps to fit the pipe in the pictures attached? one measures approx 6cm and the other 13cm. Recently unearthed this chamber after moving into a new home and finding the spare toilet was taking ages for the water to go down after flushing. After jetting i've been told that this was a system from the late 70's that requires the caps fitting to restore pressure in the pipe. Despite visiting all the usual merchants nobody can find a cap that fits either.

Any help / advice appreciated.

It's full of water. Looks like there is a blockage, or insufficient fall

Were the photos after jetting?

Does the larger one have an internal seal, if so this may fit? ;
110mm Socket Plug

Is the smaller threaded outside?

Failing that you may have to remove the Tee and access pipe and replace with new.

This is after jetting yes.
No thread on the outside of the smaller hole.

Thanks for the link

Cut it out and replace it ,why is it full if its been jetted surely it should flow away my guess theres no fall on the drain run they will be back in no time doing it again ? Kop

Would something like this not work?? Not sure what sizes are available

Looks like pushfit pipe. I'd be more worried about the water sat in it than blocking the holes.

Never heard that one, don't know how they think them up, "needs pressure in the pipe?".
