    Can someone tell me where i can find (or just post them) how many gallons per hour the standard sized hole diameters for an overflow will drain. I am specifically looking for:

    3/4"
    1"
    1 1/2"
    2"

    thanks!

    poppins - thanks, i know about the RC calculators..but i want to know specifically what each will do by itself, to my knowledge the RC calculator is for calculating you total drain/overflow turnover

    garrison - ha..your funny, with a comment like that i know you did not attend high school with me..

    backwards RC calc. worked...for those who are curious and for future note (all are approximate, but pretty damn close)..

    1/2" - 150gph

    3/4" - 350gph

    1" - 600gph

    1 1/2" - 1325gph

    2" - 2350gph

    3" - 5275gph

    wow..3" pipe really dumps!
