If the pool and spa are on the same level (spa not raised), that is normal operation. The levels will equalize with the pump off.I believe my spa is losing water when the pump shuts off, but the water is not going into pool. If I isolate the hot tub the pool loses no water. When the hot tub loses water it only goes down enough to be even with pool water. I’ve installed plugs in all holes in hot tub and still loses water. Very confusing. Replaced check valve on return line to hot tub, still leaking. Can anyone give me ideas here?
Thanks in advance.

Do you have automation? Are you sure the suction valve is closing completely? Is there a check valve in the spa return line (there should be)?Overnight the spa drains down. Next day pump turns on and fills spa back up and pool level goes down. When spa is isolated pool does not lose water.
Hayward OmniLogic, Jandy Aqualink, Pentair Intelliconnect/EZTouch/Intellitouch, etc.Replaced check valve in return line, same problem. Not sure what you mean about Automation.
A picture of your system would be good. Did you plug the main drain? It is possible water could leak back through the suction valve.None of those.
I’ll get a pic tomorrow. Haven’t really looked at valves, just know water is disappearing.A picture of your system would be good. Did you plug the main drain? It is possible water could leak back through the suction valve.
If all valves are good and in the correct position and the leak still exists its time to call a leak detection company.
Pay close attention the the pool water level with the system running and then after the spa drains down. You may find that the pool level has gone up a bit. Depending on the size of the pool and spa it may not move much. If you're not having to add water to the pool more than usual the water is most likely draining back to the pool through a leaking valve.I’ll get a pic tomorrow.
