How do you blow out the pipes on an Hayward DE Earth Filter system on an inground 16 x 32 pool with 2 skimmers and a bottom drain when closing the pool for the season?
I have the exact same pool and I live in NY. I have to take apart my equipment and store it. First I backwash the DE out of my filter and then open up the filter plug to drain all the water out. I then disconnect the filter from the multi port. I then disconnect my pump unions and take my wet dry vac and place the vacuum hose on output of the vaccum. I stuff the hose into the suction line that I just disconnected from the pump. I then blow the lines in reverse and plug each including skimmers first and then returns and finally the main drain by closing off the valve. My skimmers and main drain are one 3 port jandy valve. One side closes the skimmers, one side closes the main drain and one side closes both off. Once you plug the skimmers close the skimmer side and work on the main drain. Once that is done close the valve completely. Next are my returns which also work on a jandy port valve. I do the same thing to the returns and stair jets. Don’t forget to also blow out the water from y
