Anti-Rat Rodent Barrier 110mm Toilet Outlet Drain Waste Soil Sewer Valve

Good quality and works well, very easy to install

In my case worked well. As I had access to the end of my pipe on the manhole, that is that it went in at a higher level than the main through pipe, I could just push in end of pipe with a little washing up liquid for lubrication. Ok it's made of plastic but the price matches this. I do put some oil on spring occasionally to try to prevent rust and breakage and it won't last forever. I will buy a spare sometime for that occasion.

The rat cover is easy to fit in a standard drain, it just pushes in. My only concern is, it is spring loaded and not sure if the spring is made of stainless steel. Also the flap being plastic although it works fine at the moment not sure how well it will withstand Rats teeth and claws.

Nice tight push fit for a 110mm (4inch) pipe and a strong enough spring to stop the valve swinging or flapping around. I'm using it on an outdoor surface water pipe as a rodent barrier so only have water behind it and for me its very good valve for money. Im not sure how it would fair with sewage behind it , I can imagine it might build up due to the resistance of the spring?

Had an issue withrays coming up the toilet unfortunately.... Had oirchssed tis and added it to the flu at yhe base of the toilet and it works fine! Can go to sleep comfortably now! Thank you!

The rat chewed through it ats plastic.

Ray trap fitted perfectly into down pipe. As to why it needs to be white would be better if all black since rats are attracted to light.Not going to provide pics does not seem appropriate
