Purchased a new home a few weeks ago with a pool and a spa. The spa has a waterfall that falls into the pool when the pump is running. I started to heat the spa today for the first time and noticed that when I do, the pool pump stops filtering the pool. Is this how the system should operate while heating the spa? It seems strange to me because if the spa takes 10 hours or so to heat then the pool will be neglected and not get filtered that day.
Thanks in advance for any assistance.
