We are pleased to announce implementation of bulk discounts on non return valves across the store. The more you order the higher the discount you recieve! You can view the discounts on the product pages and also on the cart checkout.
We have also added our 4″ mini valve to our product lineup which is very useful for tight sewer pipes with bends etc the link for this product is https://www.sewerstore.co.uk/product/110mm-non-return-valve/
