Hi all... well its been a long four years of waiting and saving, and Saturday (day after tomorrow) we actually begin digging.
I am ordering equipment (this is a DIY IG Gunite with spa, shared body of water), and trying to figure out the layout of equipment and plumbing.
I will have:
~20000 gal pool 20X30' rectangle with a 10X10 tanning shelf.
9'X9' square spa w/12 or so jets. Waterway Polystorms of varying flows.
5 returns, 1 deep end, 1 shallow, 2 tanning shelf, and 1 spa.
dual main drain.
spa drain (s?) (a strip drain or dual sump drains? suggestion?)
main filter pump the new pentair 011018
separate jet pump, also the 011018, so we can adjust flow as desired.
cartridge filter (ccp 520)
SWG intellichlor IC40
Pentair Nat Gas heater 400KBTU
Pentair 120r Heat Pump (mainly for cooling the pool in hot months, but hey, cheaper heat is a bonus)
Pentair Intellitouch automation
a few deck jet water features
To the subject at hand:
I need advise/help in figuring out the plumbing layout on the equipment pad so I can order valves and actuators.
I figure a separate jet pump from the rest of the system so that is easy.
But the Arrangement of the rest of the equipment is leaving me a bit overwhelmed. I figure a 4 way intake setup with individual ball valves for filtration, with an actuator 3-way to isolate down to the spa when it is in use and heating, proceeding from the 3-way to the pump, to the filter, out to the heater(s) (heat pump first then the gas heater), then to the SWG, and then to the pool and spa, pretty much according to this diagram:
with an actuator controlled 3-way and make-up loop for the spa. The Deck jets will be driven by the circulation pump, with an actuator controlled valve on the pool return circuit.
Is this the way its usually done?
I realize that when the spa is in operation, the pool will not be circulated or filtered, but spa use in the grand scheme of things is minimal compared to pool filtration time and circulation time in total.
Input, thoughts any thing appreciated!
Super excited to get started, will be sharing pics and diagrams this weekend. I am just afraid to jinx things by posting a pre-dig diagram now.
Is there another way its done?
