I have a HayWard DE filter. that's giving me trouble.
I just disassembled it and removed all the grids and all the grids and reloaded it with DE.
Started off at 12 PSI this morning, and by the end of the day it was at 25 and the flow was so log my SWG was giving a no water error.
This is the second time I've cleaned the DE grids in 2 weeks because of the same issue.
