I tried to enable the heater a few days ago. BIG mistake!! Now I know where my metal came from. Could actually hear it rushing trough the piping towards the returns. Before I could get the valves rotated back, there were clouds of metal flakes spewing from the returns. Took me hours to vacuum it all up. Good thing I had placed a sock on the skimmer basket. Caught almost a pound of stuff.
So now I want to find a low cost replacement. At least that's what I figure I'm going to have to do.
I know, I know. Need pics!
