"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."
"Have been using these traps for a long time now and they have been great, but the last few i have used were very poorly made. The plastic around the seal on the bottom curved section of the trap were mis-shapped. This wouldnt allow the rubber o ring to seat and seal. A couple also had o rings missing. probabley thrown 4 out of the last 10 away. Not happy. Think flow plass need some better quality control."
"I fitted one of these and found a leak but as I'd gone passed the point of no return removing the old waste I was stuck. The leak was due to a deformed section of the u moulding where it contacts the rubber seal. I should have taken note of other reviewers comments. Very poor quality control by FloPlast. If you find the low price irresistible I recommend you buy 2 or 3 so you might get a good one and return the leaker's or not used ones for a refund. Come on Screwfix you can do better than this."
