## Customer Reviews

### ⭐⭐⭐⭐⭐ It worked
*by D***C on 6 November 2023*

Replaced a botch up by a so called plumber on our recently (3 years old) new house, so out of warranty. Fitted in 5 minutes all hand tightened, no leaks.... delivery was next day so highly pleased.....

### ⭐⭐⭐ Three Stars
*by T***I on 22 May 2017*

Product as described.

### ⭐⭐⭐⭐⭐ Excellent
*by T***R on 27 September 2023*

I was getting foul smells from the sewers as my trap was syphoning. I tried an anti syphon trap with the air vent but that didn’t work. I purchased this and no more bad smells. Recommended
