I have an older model of this Hayward filter:
SwimClear Multi-Element | Filters | In Ground Pool Filters - Hayward Pool Products
Every time I clean the filter elements and put everything back together, I always get a leak at the clamp. I can't seem to finesse this thing. I take it all back apart, lube the o-ring, and 50/50% the leak will stop. Also, 150 inch pounds seems not enough.
Can someone tell me the secret?
