Pump sizer ( Loop) to reduce large pumps flow by 2-4 gpm
Thumbnail Filmstrip of Pump Sizer ( Loop) to reduce large pumps flow by 2-4 gpm Images
Pump Sizer = Will lower the effective flow by approx. 2 gpm
Also called a " Pump Loop"
6001A-20 valve
7003 jet holder .060 to .090 pills
This is not scientific - A .060 pill usualls results in 2 gpm loss
use this to make your pump behave approx. 2 gpm lower than it does now
So a 17 gpm will approximate 14 gpm * These are not meant to be exacting, simply to keep from running a giant main by pass pill
It is not intended to make every pump behave in a sense that you only need one size pump.
It will get you by when you have a pump that is approx. one size too large for you current needs
We highly encourage you to get the correct pump for your needs *
