Water and Rodent Non Return Valve 110mm / 4 inch

Excellent product, easy to fit and does does not clog.

Robust and easy to fit.

Hopefully will do the trick . Fitted easily. Feel it is a little expensive and would be better priced under fifty.

I have used other types of rodent valves previously to properties I own. These are a little more expensive, but much easier to fit and very effective. The main access for rats to a property is the drains, often via a break or a disused drain under a new extension, this time the rats disappeared in 2 days. They can leave but can't get back in, they look really confused when they came back to try and regain entry. Exclusion, is better than poisoning and all the hassle that brings.

Was having problems with rats in downstairs of my house, blocked everything up all holes they was still getting in, someone suggested buying these drain blockers because they could be getting through the drains and into the walls, bought 5 of them blocked every drain entrance and it's been 2 week no more rats, so easy to fit just push them in. Great product

This is the third valve I have purchased following problems I had with rodents gaining access to the wall cavities and ultimately to the attic. The rodent had gnawed its way through a flexible pipe beneath a downstairs toilet. The first two valves which I purchased five weeks ago I placed over the clay pipe access to the toilet and the other to the main sewage pipe run behind the house. I heard the rodent leave through the valve then it tried to get back in (I heard it banging its nose against the valve cover) and have heard nothing since. I bought this third valve to cover an en-suite sewage pipe as a precautionary measure. A most effective piece of kit.

Great value for money and fit nicely in the pipe. It's stopped the rat from trying to get in through my pipes. Held strong for the past few months as it was an excellent option even if it is just for piece of mind.

Appears well made and a simple push fit to locate In the pipe in a matter of seconds with a tap by hand. Came with a disposable rubber glove also.

schwer einzubauen, besonders rostete schon nach einem halben Jahr sehr stark (bei Überprüfung/Reinigung festgestellt)

Una maravilla. Ha sido colocarlo y fuera olores.

Ottimo prodotto

Goed ontwerp maar veel te duur voor wat het is. Binnen het jaar zijn mijn 2 kleppen al aan het roesten. RVS staal volgens de beschrijving?
