Question about Hayward SAND FILTER, PRO SERIES
The sand filter is at 60 psi. maybe i didnt back wash long enough.
I don't have that particular brand, but it is not good that the PSI is that high. Backflush for at least 3 cycles of 60 seconds each.
example: Turn off pump, move to Backflush turn on pump for 60 seconds. Turn off pump, switch to rinse, turn on pump, run til water runs clear.
Repeat 3 cycles. If the PSI still doesn't lower, you may have broken laterals in the bottom of the sand and will need replaced.
Hope this helps. Good luck!

First check your return valves to be sure their open, The picture shows a dial valve but if you have a piston B/W valve you should pull this out and be sure that you have two discs on it. The bottom one has been known to break off and it will drop and seal off the pipe going back to the pool. This will make the pressure run to the limit of your pump. Getting the broken piece out will be a trick but then you just slide the new on in.
One way to get the bad piece out is to cut the bottom pipe off the valve and pushing it out. Another way is to take a looong drill bit and drill the disc out and get a wire or the like through the disc and pull it out. Or this may be one for a pro. Good luck.
