    Filter max pressure.

    Quick question. I hear to filter 24/7 during a slam but I've always been scared to run my pump while I'm not at home. When it's clean I'm not scared but during a slam it could get dirty pretty quickly.
    My question is what could possibly happen. I know the recommendation is 8-10 psi higher than normal pressure. If while I'm gone it goes higher than that... What are the possible repercussions? Blowing up? What all equipment could be damaged?
    Just something I was thinking about.

    I'm pretty sure they are good for up to 50 or 60 psi.

    The only thing that will happen is the flow rate will go down.
