Previously used 40mm waste pipe and compression fittings with no problem - everything gets tight However today I bought and fitted 32mm waste pipe and 32mm compression fittings (to replace the bathroom sink piping with new sink also) and during tightening "it just didn't feel tight". When the pipe went into the 32mm right angle bend - it "rattled about" and only tightened at the final quarter turn I got the pipe and fittings from B&Q - could the pipe be for weld fittings only ? Need to know before I box in the pipework !!!
ok thanks tom.plumb guess the bigger 40mm fitting just give you more of a "feel of tightness" due to the thread size
Might be worth checking but on the fitting, are both the nylon washers in place, in front of the rubber seals These help to compress the seal as you tighten them up Always see loads of these blue and red washers laying loose on the shelves amongst the fittings Just a thought
The white push fit pipe is a bit smaller. If you have that it would explain it. Maybe a few wraps of PTFE and some silicone.
