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

Well made, worked as hoped. Sorted out a longstanding problem and many months later, no issues.

Bought this as we had rats, easy to place and had no problems since. Good value for money and its very sturdy. Fits all drains looks ok

Easy to fit, no sign of the rat since

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.

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

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.

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.
