Thanks to this amazing site, I decided to fire the pool company and take care of the pool myself. I am so happy I did it! I already found multiple issues and the pool is looking great.
There is one basic question that I am not sure about: how to operate the diverter valve. My question is: where should the OFF position on the handle be for:
(1) Skimmer only?
(2) Main drain only?
Right the OFF position is on "B" and I am not sure it is the right position. Also - there is a plastic pin that blocks the handle from going all the way to OFF at "C" - not sure why.
Thanks for helping a newbie!!!
