Having purchased and installed easy to fit and nice feeling you’ve cured the vermin problem.But after time because there is a lip for waste to get over it eventually blocked the drain.if you have a vermin problem don’t go for this cheap option go for a more expensive stainless steel one with no lip because after you’ve paid to get drain unblocked it will work out cheaper

I placed one of these in our sewer outlet 4 years ago, approx' 2 years back I had to replace the flap/door as it had been chewed through...the bottom of a food tin can works well here. We've just started hearing the odd rogue rat in our loft/walls so checked this valve only to find it has started to perish/fall apart. For the relief given over 4 years it's been a really worthwhile purchase, if anything it's a cheap way to see if the horrible little things are getting in through your sewer in the first place. I'm going to replace with a stainless steel one but for ease of fitting/cost etc. and relief given I'd definately recommend. Also we've not once had a blockage since fitting.

Arrived promptly and looks fit for purpose, obviously will only be able to report back on performance after a heavy storm and so far haven't had one.
