Indoor Covered Hot Tub losing water
I have a hot tub that is losing water. It is in an indoor room that has a sliding glass door leading to my deck. The hot tub is always covered. I have not been able to use the hot tub much so it is not uncovered often. I just had a repair guy come out to look at my thermostat on my heater. That issue was fixed, but I noticed my water level has dropped about 2" in the last week since I added water. The room has a heating duct going to it so it isn't super cold in there. I'm just trying to figure out what is going on. Any ideas are greatly appreciated!
