I have a question about my Hayward micro- clear 72sq.ft. D.E. filter
I have a 2hp pump also Hayward .
With 2" plumbing .
What should the Standard operating Pressure Be !!!
And my installer installed a Heater bypass valve becuse when the Heater was first installed in 1998 it started making a loud banging sound , so he came back and installed a heater bypass valve, with it slightly closed the banging stopped.
Also with clean D.E. the filter pressure is 15 lbs , with the bypass slightly closed .
With the bypass open the pressure is 30 lbs (clean D.E. )
I have not noticed the banging with it open or closed anymore ? Should i run it open or closed ???
Does it really matter ???
