Extensive pool remodel underway. All decking has been removed and plumbing is about to be replaced. 2" going back in. There are 4 return jets in the pool (ABCD) and 5 jets in the spa. The jet loop on the spa is NOT being replaced, but the plumbing to and from the spa will be (2"). Also looking at 3 sheer descent waterfalls (12", 18", 12") coming off an 18" tall wall behind jets A,B, and C.
Will be running everything off one pump to start off, but was reading a thread today that suggested running the plumbing so that an additional pump could be added later- great idea!
So, if you were plumbing this pool, and wanted to set it up to add a second pump at a later date, how would you do it?
Each grid is 2' and there is a main drain that isn't on the diagram.
