"As title, I'm not the only customer who got this waste trap home only to find its rubber O-ring(s) missing, Fully check the bag's contents at the counter before you leave the shop. Apart from that, it does the job just fine. Does not incorporate a non-return valve on the waste spigot, though."
"I bought this because it was the only one in stock with an appliance connector. A few weeks later it was blocked so I took it apart to empty it. So far, so good. Putitng it back together, the O-rings are so skimpy and soft that they won't stay on their raised lips making it impossible to reassemble without the seal bulging out and failing. Add to that the top nut on FloPlast traps never seem to fit the outlet of the waste - you can't tighten them enough. Just as they come tight they pop and slip back one thread. Replaced with a proper McAlpine one. FloPlast's push-fit stuff is fine, as are their pan connectors and lots of other stuff - just their traps are such rubbish."
