We have used this product many times and it has never let us down. We would switch to another brand were it comparable but cheaper ... I think the product is expensive for what it is
This has stopped the smell from my WC. Very quick to install, it just screws on. Best £26 I have spent in a long time. I am unable to comment on longevity.
Bough this AAV to solve an issue in my bathroom between shower and bath waste pipe, this solved the problem of air drawing out the water from the shower trap, making noise and leaving a sewer smell. it was easy to install and worth ever penny. A* product
Found one of these behind a panel in my bathroom during a refit. It was 29 year old and had developed a fault whereby it let foul air into the bathroom. I was very pleased to point this out to my Wife as she kept blaming me for the hideous pong that sometime occurred! I was pleased to discover that the device was still manufactured and also available next day from my local Toolstation. It took 2 minutes to remove the old one and fit the new one. I was a bit concerned when I discovered the new one rattled but the old one didn’t. I contacted the maker, McAlpine, via their web help form, not expecting a reply for the usual 2 or 3 days but was amazed to receive a phone call from an awesome Scottish support guy who very enthusiastically explained the rattle was normal and the fact that the old one didn’t, meant its rubber diaphragm had perished and swollen hence it not sealing properly. One of the best support calls I have ever taken, very impressed with McAlpine. As for Tool Statuon, also impressed, ordering was a doddle, part came in on time etc so good all round.
My experience so far is that these things fail after 2yrs. The rubber flange fails to stop odour.
neat fitted easily seems fine . no issues
Does exactly what it should do. Straight forward installation. Reliability unknown - only just fitted it.
