Ok Guys, be easy on me . So, after owning my pool for a week I get the spa to turn on and get hot in about 15 mins... was about 102degrees. The next morning I woke up to the spa being completely empty and pool having tons of water. After 3 hours of trying to figure out what to do (get the air out of the line, set the valves right, etc... i get my spa filled). So, I think I have everything figure out. I know exactly where each of the 3 valves should be for "normal" pool operation. My understanding of normal is... drain from pool, return to spa, and have the skimmer working. Here is a picture of my equipment and a diagram of what is happening. Is it true that to operate the spa we need to drain from spa, return to spa, and of course heat the water? I have 3 valves on my equipment. 1 is turns of the jets for the spa (2 way), 1 is pool return, spa return. The second valve I believe but not sure is the pool drain, spa drain. What in the world is the 3rd valve for? My Aunt told me i have a setup for Solar Heat if I ever set that up in the future. Basically, how in the world do i get the spa to heat lol. The combination I thought was working was valve one to right (spa return), valve two to right (spa drain), valve 3 up (no idea why but down does not seem to be correct). When I did this, the little water fall thing (drain from spa to pool) stopped draining... jets were on and all seemed well. After about 15 minutes I noticed the water level in the spa was dropping over time (not alot but it got below the blue tile in the pool). I set everything to my "normal" setting and it filled the spa back up and the water drain came back on. Is it possible that the valve 3 i need to set somewhere in the middle? Would it then drain from both the pool and the spa together? P.S. The spa is raised above the pool (typically pool/spa combo ) Thanks for any help, I really dont want to pay a pool guy to come tell me this stuff... i really should be able to figure it out lol. http://img85.imageshack.us/i/sdc17291m.jpg/ http://img85.imageshack.us/i/sdc17291m.jpg/ http://img163.imageshack.us/i/sdc17289.jpg/ http://img24.imageshack.us/i/pooloperation.png/
