I am looking at purchasing a home which has an in ground fiberglass pool and spa. The spa doesn't spillover into the pool and they appear to be completely separate systems. The equipment pad has two pumps, two filters, one heater, and one SWCG. The house is a foreclosure, so I can't ask the owner how it was supposed to work.
Can this type of system be plumbed in a fashion to use only one filter/pump? I'm assuming it would difficult/impossible to maintain the water level in the pool/spa since the amount of water coming from/going to the pool/spa would be hard to control.
Just wondering if there were any options there. I'm not really sure how the existing SWCG works for both unless they were maintaining the spa chlorine by hand. The though of running two single speed pumps sounds expensive.
