Hey everybody, thanks for checking out my post. I just purchased a home with a pool/spa and am having some issues figuring everything out. I've had a pool in the past but no spa and it was set up different. I learned everything I know from this forum! I've been tirelessly researching this issue but haven't had much luck finding my exact situation. So here it goes:
I don't know how old the pool is, but it has 2 skimmers and the main drain, all coming to the pump from the same line. I have a single valve that controls incoming flow from the pool and the spa. So I can't adjust suction from the skimmers and pool main drain, I can only adjust how much flow comes from the spa and how much flow comes from the pool. The spa is level with the pool and has a small spillway between the two. Right now, I have the spa drain completely off (according to the valve) and the return to the spa is completely off. Even though the drain is off, water is still draining to the pool. Basically, the spa is draining to the point that the pool is always spilling over into the spa. And after 5 days, my spa is down 9-10 inches. When I turn the pump off at night, the pool will overflow into the spa until it reaches the bottom of the spillway. Note: The spa has never done this when the pump is off, the spa will stay at whatever level it is at when the pump is turned off.
My question is, what could be causing the water to go to the pool when the spa drain is off? I feel like I'm losing more water than I should and I'm trying to test for any leakage. I've been trying to do the bucket test but I can't get an accurate reading because I can't keep the pool and spa levels isolated, I don't know if the pool is losing water and taking excess from the spa, or vice-verse.
Thanks for any feedback.......
