    4” osma fittings advice please?

    I’m doing some 4” soil and I’m having a debate about what can be done with these fittings. They’re both 45s. The double socket has a ring seal on it facing up and the spigot of the other 45 goes into it the bottom. The 2nd 45 is then glued on the spigot and socket. Is this acceptable?

    I've searched this forum but cannot see anyone else reporting a similar problem with the last generation grey Hep2O fittings: they unscrew! Our whole house was re-plumbed in 1999/2000 and Hep2O fittings were used throughout for all out-of-sight fittings - just over 200 of them. One evening...

    I understand that, at least in the USA, the term "Lead Free" means "not more than a weighted average of 0.25% lead when used with respect to the wetted surfaces of pipes, pipe lead-free compression fittings, plumbing fittings and fixtures."
