Non Return Valves - 40mm £30.00
A simple and cost-effective NRV, we provide a range with single or double flaps to meet current UK building regulations. These NRVs are fully automatic with flaps that prevent any backflow of sewage into a property, also offering an emergency manual locking mechanism.
Non Return Valves – Ideal for properties that suffer from long-term flooding
For properties that suffer from long-term flooding or permanently high water table levels, we offer a different type of Non Return Valve solution. It acts similarly to a regular Non Return Valve, but additionally allows the use of facilities during a flood emergency.
By incorporating a macerator, under the control of a sophisticated control panel, it will allow sewage waste to be pumped against the back water in the drain. It is effective with a head of up to 8 metres.
