    How much psi should i be running on my filter?

    I have a hayward s244t witch has a maximum psi pressure of 50.
    My filter runs at 45 psi is this normal,i can't remember if i use to run at 25psi or 45 psi but i think i use to be at 25 psi 5 years ago when my pool was new.

    Thanks

    No, 45psi isn't normal. More than likely you have a bad gauge. 45psi is what you'd see if the returns were completely blocked.

    Thanks My gauge does seem a little old and it seems to maybe have a bit of water in it.I'll buy a new one today and i'll repost the results.

    Thanks for the advise.
