    Return Spigots in pool

    Is there a rule of thumb in selecting the outlet diameter of the return spigots in your pool? The people who re-plastered our pool put news ones on that only have a 1/2" outlet hole and looking online they also make them with a 1" and 3/4" outlet. The 1/2" has significantly raise my pump pressure. Right now I removed the swivels and although there is no surface deflection pump pressure is down like it was.

    There might be a formula; I don't know. But I do know if you double the pipe size, you increase the volume four times. A single 1" pipe is the same as four 3/4" pipes. How many returns do you have?

    I have four returns like above and a fifth for my Polaris 280. When I run the 280 I do turn on a booster pump but when off return water still flow out that outlet too.
