Have had our beach house with its pool for 15 years now. Had it completely replastered, new coping, new waterfall feature 3 years ago. New Hayward pump last year.
The Pentair 60sf filter is original...going on 25 years is my guess but grids and valves have been replaced over the years.
I never knew how to backwash it because I never had to, until Sunday. Pool got opened on Friday and they removed the plugs and cover, fired up the pump and added DE.
I vacuumed it Saturday and the pressure increased to where the suction and discharge were weak...tons of pollen floating on the surface plus the other junk and grit that makes it's way in over Fall and Winter. Don't have a multi port valve, it's a push/pull valve and it is stiff. I found a 3 minute YouTube video where the guy explained it in super simple terms.
Soaked the push/pull valve with PB blaster, went inside for an espresso, came back out and climbed on the equipment deck and had my son kill the power. Yanked the valve up, it was still very stiff(0 rings)but opened completely. Son powered it up and bingo...let it run for 1-2 minutes until clear. Worked great. Added 5 lbs of DE through both skimmers and it's looking and running great.
YouTube is great
