Our Client has had a ongoing problem with Rats getting into the property with no external entry points found externally of the property. The client did have insurance and a pest control company was called out to deal with the problem. They advised baiting the sewers and fitting a non return valve but they were unable to install the valve and advised contacting a local company.
We discussed the problems with the client and visited the site armed with one of our 110mm non return valves (ratblocker). The chamber was deep and as such leaning into the sewer with the client holding my legs was a interesting start to the day! As you can see from the picture the only outlet from the property is a 45 degree angle outlet and our full stainless steel valve fitted perfectly.
