About Us

Sewerstore are manufacturers and designers of sewer solutions and drain products. We are a company based in Swindon Wiltshire and have developed the non return valve or (drain rat flap) to protect homes and businesses against rat ingress into properties. 

We originally started developing a drain valve due to requests from customers as we are a pest control company and have been installing plastic versions which became chewed by rats. 

After much trial and error with different types of metals we decided on using marine grade 316L stainless steel due to its anti corrosion capabilities. This was the first stage and as we wanted to sell a product which has a balance of reliability and cost effectiveness we decided it was necessary to build our valves in house. 

Building in house required tools needed for metal cutting including CNC plasma machines and welding equipment. Initially we started using hand held tools. We have now invested in computer controlled CNC machines. 

Having this capability allows us to carry out custom builds for clients and allows us to sell direct to Pest Control companies, Drain Contractors and Business and Consumers directly while offering a cost effective product. 

We offer price discounts on bulk orders and can supply any volume. 

If you have a question please feel free to contact us and we will be happy to help. 

Best Regards

The Sewerstore Team
