I've run into an issue with my hayward cartridge filtration system. Apparently I have a serious over pressure problem that's causing the case head to crack. I have repaired it once already, I cleaned the filters after repairing the case head and 4 days later, it split again directly across from where I repaired it. The repair isnt pretty, but, it held up nicely. Oh, pressure was over 40 psi, I'm thinling replace the filters, repair the second crack and give it another go. Any thoughts out there?
