How Do Channel Drains Connect To PVC Drainage? (Video)

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.

How to Connect Drainage Channel to Drain?

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.

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.

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.
