Rats & Mice Prevention for Drains, Stainless Steel Drain Rat Flap, Non-Return Valve, Rat Blocker for Sewers, fits drains (95-110mm, 4 inch)

Really easy to fit and seems sturdy. Was worried about it causing blockages, but none so far. Has stopped our rat problem nicely!

Haven’t fitted it yet, too early to say if it works. Looks well made and hopefully easy to fit and will keep the pesky rat out.

So far so good, keeps rats and mice away, very happy with it. Fits well and does what it says. It was easy to install and good value for money.

So far so good. Installed 3 weeks ago and no sign of rats as yet. Had 2 previous issues with rats chewing through toilet outflow pipe. Easy to install and fingers crossed this is an end to the rat problem.

Easy to.fit working perfectly no sign of rat that chewed my toilet pan connector

I placed all three of these in my drains, and my only problem was toilet paper not getting through the drain, so I have had to unblock a drain, but have not heard any rats since.

Says suitable for 4-inch sewer drain pipe, adjustable. It isn't, simply not wide enough unless you stretch it or pack.out the pipe end by conceting it in... otherwise you leave gaps that aren't impossible for vermin to get past. Go for proper bigger size one up to 110mm, I wasted £38 on this via Amazon. Had in box new and unopened too long so couldn't return it.

Excellent, strong well made ideal to perform a difficult job of rat prevention

Fonctione très bien jusqu'a présent, plus de rat qui remontent dans les canalisations, ca ne bouche pas a la sortie éspérons que cela dur . Il est très facile a instaler dans un tuyaux de 100 pvc juste un troue a percer dans le pvc afin d'y mettre le boulon fournit pour bloquer l'apareil au cas ou les nuisibles viendrait a le pousser et la ce serait la cata. Je recommande.

Easy to install. Seems to work so far.

Alles Super
