Our Demand Duo Warm Water Valve is a circulating warm water valve designed to accept incoming hot water (60°C or more) from a hot water storage system, and deliver a reduced constant outlet temperature across a full range of flow rates with minimal pressure drop.

Channel drains efficiently collect and remove excess water from driveways, patios, and other paved areas. But how exactly do they connect to the existing underground drainage system? This article explores the two main methods for connecting domestic channel drainage to your drainage network.

Our FloPlast channel drains can also be connected using a D712 end outlet. This is ideal if your main surface water drainage system is located at either end of the run of channel drainage, or if you are running the water away to a soakaway. The end outlet pushes into the end of any section of the channel drainage, and a 110mm pipe or the plain end of a single socket bend can be pushed straight onto it. There is no need to solvent weld this joint as it will be sealed in the surrounding concrete.

There are two main methods for connecting domestic channel drainage to the underground drainage system, depending on the location of your existing drain pipe. Let's delve into these methods and explore the steps involved in how to connect drainage channel to drain pipe.

Meets demand. Our Demand Duo Warm Water Valve is a circulating warm water valve designed to accept incoming hot water (60°C or more) from a hot water storage system, and deliver a reduced constant outlet temperature across a full range of flow rates with minimal pressure drop.

The Demand Duo Warm Water Valve is approved to AS4032.1, as a thermostatic mixing valve and to AS4032.2, as a tempering valve. It is also approved as a warm water system by NSW Health.

The first method uses the pre-formed bottom outlets conveniently located on most channel drains. For our FloPlast Channel Drainage Grate (PVC, Galvanised Steel, and Threshold), there are three integral bottom outlets in each length of the channel drain. If the pipe that you connecting to is at a lower level than the channel drain itself, you should use one of these bottom outlets. Simply cut out the section of the base inside the circular outlet and push a piece of 110mm drainage (or the plain end of a single socket bend) straight into the outlet. For peace of mind and a completely permanent joint, you can use silicone seal on the joint, although it will be sealed inside the concrete that you set the channel drainage in.
