I have read on here that you want all of the pipes run separately. I assume that this is so it is easier to fix if you have a leak down the road. The PB told me that the 2 main drains connect together and go back to the pad but everything else is separate.
1) Should I insist that each main drain be plumbed separately?
2) I am installing a fair amount of concrete decking and ALL of the plumbing is laid out to run under the decking. Should I change the path to go around the decking?
3) See anything I should ask about or change in the contract?
Trying to think of EVERYTHING in advance is a job in and of itself....
