Hi,
First post, but have been reading it for years to pick up tips! I have a very simple question, but I have no knowledge in this area. Your advice is appreciated.
There is a manhole at the back of the property. Within a 1.5m of it, you have two rain water pipes, a toilet and bath waste going directly in to the manhole.
Do you need any sort of vent pipe on this set up, or will the open drain, and rain pipes suffice?
It's just that I want to replace the 4" asbestos cement rain pipe with a smaller pipe. I'm guessing the large pipe is just from an older rain water system, but wanted to make sure that it wasn't that size for venting reasons.
