## Overview

The Rat Blockers Stainless Steel Drain Valve is a durable, 6-inch twin non-return valve system designed to permanently block rat entry through drainage pipes. Crafted from rust- and gnaw-resistant stainless steel, it fits both clay and plastic curved drains, allowing free water flow while preventing rodents from invading your property. Backed by a 12-month warranty, it offers a safe, maintenance-free alternative to traditional pest control methods.

## Description

Steel Rat Blocker prevents rats from entering buildings through the drainage outlet. The non-return valve allows free flow of waste but blocks any rodents attempting entry in the other direction. You can stop calling your pest control and solve the problem once and for all. The Rat Blocker is an ideal solution to block rats from entering your property permanently. Our Rat Blocker is made from non-corrosive stainless steel and we offer a 12 month warranty. *Please note other cheaper alternatives only have 1 single valve which offers less protection *Rat Blocker is an immediate and permanent solution to stop the entry of rat/rodents *Rat Blockers can fit in both clay and plastic-type pipes in 4″ size. *Twin Non-Return Valves, Allows Free Flow but Also Blocks Rat Entry *Installing a Rat blocker will save you money on pest control and avoid unnecessary costs like lifting floorboards, removing plasterboards and more. *Rat blockers are much safer compared to conventional pest control, such as poisoning. Aside from the smelling rat carcass, having kids around the house with poison is not an ideal scenario. *Our rat blocker can fit in both clay and plastic-type pipes.

Review: The rat blocker was purchased for an underground drain to a domestic property in the UK. It could be placed at either end of the drain pipe but I suggest it is where the flow of soiled water enters the inspection chamber. If there is a blockage further up the rat blocker can easily be removed although it would work well anywhere in the pipe work. I asked if it was flexible but the circular casing is, in fact, rigid. This meant it on just fitted into the pipe and I only managed to go into the pipe half way because of the way the pipe had been laid. Effectively it is jammed into the pipe but this works fine. As it is so well made there have been no blockages and 'ratty' came through it tail first and I dragged his carcase out. He died from poisoning. Until I found and sorted the entry point into the drainage system other rats could get into the drain but none of them could get past the rat blocker. With its two flaps it is impassable. Water and excrement easily pass through when there is sufficient water flowing. If solid waste is sitting in the blocker the spikey, serrated edge of the flaps would impede anything trying to push past as the flap would close as it was pushed. I am glad and relieved I bought this product as it solved what would have been a difficult problem. Obviously, insert the rat blocker in the pipe with the flaps opening in the downward flow direction. My advice is to insert the blocker ( I did not need to use the bolt which is the clamp for larger pipes I presume) and sleep well.
