So I returned home to my pool install. Fully plumbed and wired now. However the plumbing isn't quite what I expected.
Let me describe the setup:
Skimmer and main drain comes into the pump.
Pump goes out and into the filter
Here's where I was surprised: Out of the filter goes to another valve, one way goes to the heater (heat pump) and then to the returns on the shallow end stairs. The other way goes through the SWCG cell and to a different return in the deep end.
Is it normal to split the flow between SWCG and heater like that? And go to different returns? I suppose it shouldn't matter as neither requires a high flow. Just not what I expected... I figured they'd be plumbed in series: pump -> filter -> heater -> SWCG -> returns
