New to forum, would appreciate any advice ...
Getting close to starting an inground gunite 580 sqft w/ 9' round spa. Looking for opinions on what pump and plumbing combo to go with. Equipment will be 90' from nearest edge of pool. Here's my first take on pump/plumbing setup:
3 HP pump dedicated to spa jets with 2 HP blower motor. Would like to have 12 jets in spa (8 up top, 4 bottom) but would be ok with dropping to 10. Plan to use the waterway T jet assemblies. Plumbing would be a main drain with 3 inch pvc to pad and a 2.5 inch return to the jets.
3 HP VS pump that primarily runs low speed for filtration and heating with returns to pool jets and spa return. Higher speeds would be used for 2 bubblers in tanning deck, polaris, and future waterfall. Main drain would be a 2.5" run to pad. Skimmers would be another 2.5. I guess the returns: bubblers, pool jets, spa return, polaris line, and waterfall line would all be 2"??
Is the spa pump/blower motor setup sounding good for that number of jets at that distance?
How's my spa plumbing size sound for that setup?
If I go 3" spa main drain, do I just step that down to 2" at the pump?
Pool/Other Feature Questions:
Can a 3HP VS pump handle everything I've listed there? How do I determine how many GPM a 3HP VS pump can push at various settings with a 90' run?
Any thoughts on my plumbing sizes?
I don't know much about automation systems. Could I control all the intakes (skimmers/main drains) and direct the outflow (w/ option to bypass filter to not put too much flow through it) with actuators and automation sys? My goal here is to have all this stuff and not use 3 pumps.
Sorry if I've asked this in an unorganized way ... I'm just beginning to wrap my mind around all the terminology.
