Question about Hayward SAND FILTER, PRO SERIES
I have a 1995 Vari-flo model 71113. The pressure is only at 14psi. I was told when we bought the house that 25 is the correct operating pressure. What can/should I do? FYI- pressure gauge is brand new. Pool is inground. Thank you.
The actual pressure depends on how clean the sand is, how well the pump is pumping, how clean the skimmer and pump baskets are. The rule of thumb would be when the filter pressure raises 8-10 psi above whatever the pressure was when you first started the filter with clean sand, clean baskets, good pump, When it reaches the 8-10 psi, it's time to backfulsh. A low pressue, with adequate return flow is what you really want. See Hayward's web site for a manual. http://www.haywardnet.com/inground/products/manuals.cfm
