Can I use flexible waste pipe from the waste outlet of the Easyfit+?

Easyfit+ waste pipe considerations

We suggest using rigid waste pipe if possible as best practice, however flexible waste pipe can also be used.

If using a flexible waste pipe it is important to ensure there is a constant, smooth water path through the waste pipe and it is at the correct fall gradient. If it is not and water is able to "pool" within the pipe then it can cause a flow restriction. This can cause bubbles to come back up the drain during operation, restricting flow further and making noises.

 

The Easyfit+ Installation guide can be found here

Building regulations document H gives guidance on waste pipe sizing and fall gradient – Document H. Document page 9 (PDF page 11) has a useful drawing to show this.
