Water and Rodent Non Return Valve 110mm / 4 inch

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

I worked which was my toilet in the drain and simply pushed this in. It went in easy and I have the peace of mind no rat will be coming up my drain pipe.

I easily fitted this in my drain, using a bit of force. Waste water flow seems unrestricted but so far it is too early to say whether it prevents back flow.

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

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.

Update - December 2024 I've purchased 3 of these now but one of them I had to return because I suspected that it wasn't sealing properly, I was right I because I filled it with water and it leaked because the edges of the body next to the seal were rough. This is meant to hold water and seal to prevent backflow. The unit arrived in a box and a bag, with a different glove - all of the other 3 only arrived in a bag with a nitrile glove - check the units carefully and do as I did test it with water to make sure it doesn't leak like a sieve as in the video. Following on from a recent floor and bubbles being blown back into our toilet, I decided I needed to get a "toilet" bung but whilst looking for a flood barrier I found this in one of my searches - and decided to purchase it from Amazon as it was the cheapest I found any of this style of non return valve! Fitting it wasn't easy as I had to get into the sewer and place it on the lower of the two outflow pipe work but I couldn't bend down to push it in by hand, so I used my foot and it slipped in with a bit of effort but went as far back as it would - due to the other pipe protruding out slightly more than the lower one. All in all, it works very well, lets see how it holds up to any further floods we might get and fingers crossed it stops my toilet from having flatulence and as a bonus stops any furry friends from popping their head up in the bathroom!

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.

L'ho installato ormai da un anno. Prodotto davvero costoso, ma fa perfettamente il suo dovere!

Lo he comprado para evitar el retroceso de las aguas pluviales hacia una rejilla que tengo en una rampa del garaje. Espero que haga su función correctamente. Parece de calidad y es fácil instalarla. Mi duda es si valdría para aguas sucias de inodoros ya que la tapa se levanta poco. Es muy caro pero si cumple su función valdría la pena. Trae un solo guante desechable para instalarlo, por el precio podrían haber incluido un par.

Odeur egouts

Après avoir acheté l'embout d'évacuation anti-retour (Capricorn Acier inoxydable 9-5030-110-00-03-11 Rabatteur de fond, orange) qui bien qu'assez bon marché n'était pas adapté à ma situation (tuyau d'évacuation générale des eaux usées à raz de la conduite du fond du regard empêchant son installation et le respect de la pente) et que j'ai retourné, j'ai recherché un produit adapté à mon cas de figure. Le seul qui semble exister au monde semble être celui-ci, mais il s'avère très cher pour ce que c'est. 75% du prix semble rémunérer l'idée elle-même. En effet, tout est bien pensé dans ce produit : les ailettes en caoutchouc pour le rentrer aisément et en toute étanchéité, la pente respectée au fond du tuyau et le clapet renforcé et verrouillable. Il y a même un gant en latex fourni pour l'hygiène (pour le prix, ils peuvent se le permettre). Une fois reçu j'ai eu un peu de mal à l'installer, mais pas tant que ça vu que le regard est aussi profond que la longueur de mon bras. J'ai farté tous les joints souples qui permettent de l'enclipser aisément (si on est bien en face et à niveau) avec de la vaseline. Une fois bien installé (j'ai même pu le retirer plusieurs fois jusqu'à trouver la position parfaite), j'ai eu un petit doute sur l'ouverture du clapet qui est assez lourd, craignant un bouchage de mon réseau d'évacuation. Alors ce matin après un petit-gros caca je suis allé vérifier mon regard et quelle surprise de voir mon étron dévaler le regard en ouvrant le clapet avec une fluidité admirable malgré la pente faible et de voir le clapet se refermer juste après son passage : aussi beau à voir qu'un équipage de champions de bobsley. Un bien bon investissement en cas d'inondation des réseaux d'eaux usées donc.
