I've got to install a soakaway for the rainwater off my house. I've got a pretty good idea as to what is reqiuired , but have a couple of queries.
Do I need to get Building regs approval ?
Is it necessary to fit a "gully" where the down pipe enters the ground? if not how do I connect the 3" downpipe into the new soilpipe?
I've read that lining the pit with a weed protective sheeting is a good idea --- could this affect the operation of the soakaway ?
What is the minimum fall for the pipe - I've seen various figures on different websites ?
Any other general advice /hints will be appreciated.
