For the second year in a row, I'm pretty sure I'm doing something wrong while opening the pool.
We have a 23,000 gallon pool with a Hayward EC65A D.E. pool filter (the kind with the fins, not the cartridge) and a variable speed pool pump.
I opened the pool yesterday. pH was perfect, put in some baking soda to raise the alkalinity to 110ppm, and then put in 10 pounds of 63% shock.
Here's where things seem to be going wrong.
When I turn on the pump, everything is fine and dandy. Good strong water pressure coming out of the two jets, good suction into the filter basket. Add 6 pounds of D.E., and it looks good. I'm running the pump at 3000 rpm.
When I check on it a half hour later, there's barely any pressure coming out of the jets. The filter pressures reads 16 -- it's a little lower than the green line at 20, but not super low.
I bump the filter handle 20 times, and the pressure comes back to the jets.
Half hour later, it's dead again.
Is this normal for pool opening, while it's clearing out all the algae? Or should it run longer than that before the pressure dies?
Here's what I've tried:
(1) I've tried fully flushing and re-filling the DE from the filter. Again -- lasts 20-30 minutes of strong pressure before it dies off again.
(2) I've checked the skimmer basket and pump filter basket -- both fine.
(3) I felt up into the impeller, but didn't feel anything. I didn't take it apart, though.
(4) I'm thinking it's unlikely that this is a clogged pipe because the pressure gets stronger after bumping the filter. I would think if it were clogged it would be weak all the time.
I really appreciate any advice anyone can give, as I'm sure I'm doing something wrong!
