So I noticed my filter wasn't working properly after cleaning the filter a few weeks ago and I noticed he DE wasn't coating the full grid and there was a bunch of DE on the bottom. I released all air out of the system before putting in the DE. The grids are about 4 months old. I have attached a...

So recently my Hayward 4 cartridge filter has been at around 35 PSI when running. The manifold did have a crack and I changed that last week, which I am assuming cracked due to the high pressure. I have cleaned the cartridges (about 2.5 years old) multiple times in the last month since I thought...
