Rats & Mice Prevention for Drains

After a holiday at the Seaside, we discovered rats had chewn through our downstairs toilets Flexi Pipe and the drywall behind. After two weeks of trying to get rid of infestation with traps, a professional Pest Controller pointed out Rat Blockers as a way of preventing them to enter your drains. After fitting the Rat Blocker no more Rats were able to enter our house through the waste pipe and we managed to get rid of the remaining rats in the house with the Traps. The Rat Blocker basically functions like a cat flap. It allows sewage to flow through freely in one direction, but blocks off anything that is trying to get in from the other direction. The installation of the Rat Blocker is pretty straight forward. In our case, I had to open the man hole in our garden and look for our waste pipe. The Rat Blocker then simply slides in pipe and the attached bolt gets tightened down until the Rat Blocker sits tight and can't be moved anymore. Unfortunately, the Rat Blocker doesn't come with a Pole that lets you install it, without having to get close to the waste pipes - unlike other, more expensive solutions. I didn't mind that too much, because the installation process is very fast and easy, but it might be a problem for some people - Obviously, every Drainage Company or Plumber can fit the Rat Blocker too. The Rat Blocker is made from stainless Steel and looks and feels very durable. After several weeks of use, I decided to lift the man hole cover again and check if everything is still in working order and it was absolutely fine. It seems to be a good quality product and I hope it will do what it is supposed to do for a long time. ### If my review was helpful to you, please click 'yes', thank you! ###

Just buy it. It's pricey, but solid & seems to work. Easy to fit into the pipe.

Good fit and very easy install. Used a couple of different ones before and had pest control out more than once. This blocker is the one that’s has stopped them getting up from our drains. Highly recommend.

I had a serious rat infestation in the back garden. Rats were coming up from the street sewer, and emerging into the garden through a broken clay pipe. They had established themselves in a large warren hidden under bushes. I was quoted nearly £1000 to fit four rat flaps in the pipes that can be accessed through the inspection hatches at the rear of my property - instead I bought these and fitted them myself as the pipes are easily accessible, saving around £750. Measure the width of the pipe to ensure you buy the correct size flap - there’s a bit of flex in the sleeve of the device to allow it to be fitted to the pipe, tap it into place with a hammer (not too hard - you don’t want to break the pipe). The bolt prevents the water flow from pushing it deeper into the pipe. Take great care in fitting them as the teeth around the edge of the twin flaps are wickedly sharp. Always wear protective gloves when fitting. No rats have been seen in the garden since I fitted these six weeks ago - so far no problems with blockages either. Very happy with the result.

This is very expensive for what it is but I bought as I had a rat problem. It was fairly easy to install - problems were more down to the shape of my drain than the product. Too early to say how effective it is, but it is fairly simple product so it should do the job OK. A price worth paying, but having said that, I have bought another for my surface water drain and I found one considerably cheaper that should be almost as effective.

I had a rat problem, realised when rat chewed my sewage pipe to get access. Was confused what to do and found this product. Nice quality and easier to install. Just opened the box and found my sewage pipe and pushed it inside. Easy DIY and sturdy built.

We had issues where the Rats were entering our cavity wall through the sewage pipes. Fitted these to all of the pipes and never had issues again! If you have Rats then they are most likely entering through the drains. We called a pest control company who wasn't able to solve the problem so I ended up fitting these myself. Save time and money, easy DIY and fit in 30 seconds if you are able to reach down into the manhole to access the pipes.

Brilliant, does exactly what it’s supposed to! No vermin since putting in place. Quick delivery.
