Review: Effective way to keep Rats out of your 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! ###
