I have an in-ground pool and a heated in-ground 7-foot diameter spa. When built, the construction crew recessed the spa into the pool deck, so that the apron of the spa sits at the same level as the pool deck. The spa is connected to the swimming pool via a "channel/trough" (for want of a better term...) that sits about four inches lower than the pool deck. I also have a skimmer channel that sits at the same water level as the spa channel. (See pic) My spa/pool have a single Pentair pump, with its flow determined by automatic valves.
I've noticed when I use the spa/heater, the water level raises slightly in the spa due to the pump flow and spa jets. (Expected, I'm assuming....). Unfortunately, when the water level in the spa increases, much of the heated spa water then flows through the channel into the pool--and that causes lower spa water temp, and waste of hot water into the pool.
I don't have a design where the spa waterfalls water into the pool, acting like a "one-way channel" to flow from the spa into the pool. In my case, the channel permits the hot and cold water to intermix, when the spa is in use.
If I attempt to better manage flow between the spa and pool by lowering the water levels, the pool water becomes too low to effectively use the skimmer.
Do I have some sort of design flaw in my system? Should I try to raise the channel between the spa and pool to help stop the flow of heated water from the spa?
