Good product, saves replacing whole trap, no leaks, but not sure it has eliminated gurgling
Used these before they work really good stops bath waste from emptying out when flushing the toilet and no smells coming back from soil pipe
Can't say completely satisfied with this item. Yes, it alleviated the issue of a trap emptying out elsewhere in the property, but it also allows smells from another toilet to come out of it. So, one good element, but one rather bad one.
Easy to fit AAV for bathroom waste. Not fitted for long enough to evaluate quality and how long the seal lasts
As ad. Available & quick to pick up. . . . . . . . . . . . . . . . . .
East to fit - does the job. Quality made item with a good finish
Have used one of these on my en suite and it’s been absolutely fine since install a few months ago. It was ready to collect from store same day and collected from the pleasant and helpful staff there, as usual.
These are great, good quality devices that solved our problem at hand
Great staff, great prices and great products as always
Just the job to stop water syphoning out of bath trap. Great price and great service from Toolstation as usual.
Stop our drains from gargling. Easy to fit to the existing pipework.
After plunging till my fingers blistered and then replacing whole waste pipe from bathroom to soil stack and then still having it backup and gurgle; I tried this, all my troubles went away in an instant; never knew bath waste pipes could airlock after 8 years of normality. I suppose this knowledge would be learnt at college or from a professional non of which I am or know; You live and learn….
Best option for DIY as long as pipes are movable. Silly internal ridge design instead of sliding tube piece to avoid sludge buildup means fitting can not slide along existing waste pipe even if this can be bent slightly. 30mm inset available each side means gap must be exactly 100mm wide to allow secure fitting into existing slightly bendable waste pipe and sludge build up is therefore inevitable.
this has saved a massive amount of reworking a waste system that has caused untold amounts of issues of waste water backing up into a shower tray and wash basin. great product.
Simple system that gets rid of air locks in most/all sink installations. Easy to fix into 40mm pipework and gets rid of the smell from the drains effectively. Wish I'd come across this a few years ago. I bought a second valve to put under the main sink in the kitchen which has always had problems with back filling and leaking seals.
Works perfectly, resolved gurgling in a kitchen sink.
Good functional piping valve
Bought this to stop 'p' trap under shower from emptying but not working. I can hear the dishwasher downstairs in the shower upstairs. Gurgle Gurgle Gurgle.
It fitted neatly in the waste under the wash hand basin and solved my syphoning problem
