Standing ready to chip away a part of the main drainpipe to the basement/lower ground floor to add two new branches in each direction. The house was built in 1979, with 110mm PVC pipes so no issues there...
My first thought was to use two Y-bends in succession to get two branches, but then I got an idea about whether there was a ready-made double branching fitting and after a quick search, I found this at Biltema:
The gut feeling I have is whether the quality from Biltema should be questioned when it comes to pipes for embedding?
I can't find any other retailers selling similar double branching fittings, are these rare and should they be avoided?
