Very helpful! I am not very familiar with the pool plumbing and how returns and lines run so here is my dumb question- please explain where each of the pipes go from the valve, what they are doing. Sorry for being so naive ...12 O'clock for the HANDLE would close off one return, the one directly below the valve. 3 o'clock handle will close off the other return. 6 o'clock handle closes off the input from the filter...don't do that. 9 o'clock handle is ALL OPEN.
