"I thought the other people who had reviewed this were wingers who did not have a clue how to fit it. I was wrong. Although it looks OK it is impossible to stop it leaking without using PTFE tape on the thread. It is a very poor product!!"
"I have avoided using these for about 4 years but due to lack of space on a kitchen I was fitting I had to and just like before they leak around the bottom seal, I tried PTFE tape and it still leaked so then had to use expensive liquid ptfe and amalgamating tape leaving an un-professional finish"
"Experienced the same problem as previous reviewer; trap leaked badly once installed. Had to remove it, apply plenty of PTFE tape & re-install, then run through with hot water to fully tighten. Wouldn't use this product again."
