Why choose the Sewerstore Rat drain Flap?

We were originally a pest control company and still are and we required a solution to rats entering properties via sewers. We had been using plastic valves but they were prone to getting chewed by rats. We therefore decided to create our own using stainless steel, we decided to opt for an different approach and sell direct to end customers and in turn passing on the cost saving in doing so. Other valve manufactures outsource manufacturing but our valves are built in the United Kingdom in Swindon Wiltshire.
