The piping in our basement is arranged in a way that it is incompatible with our remodeling plans - and the drain pipe also looks quite shoddy, so it needs to go anyway. Also, due to a furnace upgrade, we'd like to rearrange some of the heating related piping too.
We have a few ideas on how to route the pipes, but would need a few answers in order to be able to decide. (Please disregard the copious amounts of duct tape and various other crazyness present... This is an improved situation, a significant step up from the original state.)
- Can the clean water pipe run below the drain pipe horizontally?
- Can heating pipes be routed below the drain pipe horizontally?
- Would there be any issues if we rearranged the drain pipe to run lower? Would it not increase the probability of clogging? (e.g. in the level the L profile sticking out from the wall - with the appropriate sloping of course)
- Would it make sense to install a non-return valve in the drain pipe?
