Pump pressure

[PoolDoc]

The calculations aren't "intense" -- nothing but adding and multiplying is required. You can get started here:

There is a little manual curve fitting and picking, when you get to the end, but that's all visual, not calculated.

The problem is, it takes good info in, for all that adding and multiplying to come up with the right answer. That means you MUST know what valves, fittings and piping make up your loop. No matter how hard you try you can't get good circulation through a 1" pipe! Think that's an exaggeration? Take a look sometime through the primary port in Hayward inline chlorinator!

Best wishes,
