Non-Return Flap Valve chamber 450mm

£349.00
Maximum quantity available reached.

Downstream of any surface water attenuation or rainwater harvesting system a non-return valve chamber is highly recommended.

The benefit of the non-return chamber is that it prevents flow in the downstream network to impact or backflow into the Rainwater or surface water system.

This is particularly pertinent if the downstream network is a combined system which could potentially contaminate a rainwater harvesting system.

Specification

Chamber Height 1300mm

Material HDPE/MDPE 

Notes

The valve chamber is not supplied a lid and these must be sourced separately

The chamber height is the total chamber height not the depth to invert.

Lead time typically 10 working days
