I'm going to start with the basics and hopefully the solution is simple. Loosing about an inch to an inch & 1/2 a day in my pool and raised spa (gunite). Shut off the equipment, looses water. Run, looses water. Turned all valves off, leave pool off, no water loss.
When it looses water there are no wet spots around my equipment and no air in skimmer basket.
There is a leak to the cleaner motor that will be repaired tomorrow, but during all the tests the cleaner is turned off and there is no water present in that area.
Lastly, we do no see water draining from the backwash line when it is leaking (that we observe).
Where is the water going and where is it leaking. So frustrated!
