inspection chamber and pipe gradients
I've set out the main part of my drainage, being old clay to new
inspection chamber to rest bend and soil pipe etc, with the gradient at 1 in 40. Two other connections on the chamber are to connect to two roddable bottle gullies (one under outside tap, other for rain water runoff - combined sewer). If these gullies are connected to the chamber mainly with straight pipe, the gradient will be a lot steeper than 1 in 40. Is this OK, or do I need to use some kind of rest bend from the gully so that the main run of pipe from gully to chamber is about 1 in 40 ? Of course, if the roddable feature is to be any use, then run needs to basically be straight. Thanks, Simon. |
