I have found a lot of useful info on this site while I've spent the past few months researching for my build. I'm putting in an inground gunite pool. Technically I'm going to be the GC, but my excavator, plumber and layout guy has done many and is helping significantly.
That being said, I'm trying to figure out whether I have the plumbing/equipment sizing correct.
700 sq ft freeform (~26000 gallons)
~60 sq ft spillover spa
2-3 other sheer descent waterfalls off of raised bond beam
Equipment pad is roughly 30' from edge of pool
Plumber is recommending 2" throughout, with 2 main drains, 2 skimmers for the main filtration loop.
He is advocating a secondary loop with 2 more drains, to feed the waterfalls (closer to 50-60 ft from pump to water features) with 2nd pump.
Should the spa be on it's own loop? Or should I just be using a big enough pump to drive both for filtering? (2 hp maybe?) Jet pump is another possibility I guess?
As far as equipment goes, I was looking at the Jandy ePump, with their larger DE filter, and LXi natural gas heater. What is the difference between a standard pool pump and their "water feature" pump?
Anyone have better recommendations? Thanks ahead of time for the input
