How much water should a pump be set to deliver per dose? The answer depends on the application, as discussed below. In cold climates, drainback to the pump tank must also be added.
1. Pumping to a gravity distribution soil treatment area
If you are pumping to a distribution box or dropbox, you do not want too large of a dose coming in too fast as it may overwhelm the box and cause inappropriate loading. In residential applications, pumping less than 75 gallons is recommended using a pump under 40 gpm.
2. Pumping to a pressured soil treatment area
