I'm sure you've all dealt with this issue before but here's my story. Had a pool built last summer. Worked fine all last summer. Company came and opened the pool this spring. First issue was a "Check Cell" light. I bought the T-cell cleaning stand and requisite acid and cleaned the cell. Now the "No Flow" indicator is on. Also, I'm pretty sure that the heater isn't heating the water. However, the return jets seem to be producing good water flow so I'm kind of stumped. The people who sold and installed the pool are not as responsive as I would hope to my issues over the past few weeks.
