This Well Manager® is set to the production rate of the well – 1.5 GPM. You can see by the water level in the storage tank that this home is using water at a peak demand that exceeds the rate at which the well can provide water. In spite of that, the Well Manager® is delivering the required volume at better than 50 PSI (in all of these pictures the needle on the pump pressure gage is past straight up – 50 lbs.)
If this had been a 1/2 gallon per minute well, the tank level would have fallen much lower and the residents would have had to wait until 7:30 AM to do the wash instead of starting it at 6:30 as in the sequence pictured above. In either case, the Well Manager® would still deliver the peak demand volume at a similar pressure. The owners of the 1/2 gpm well would get the same performance from their plumbing system as the folks with the 1 1/2 gpm well. The only difference is they would have to space out the wash.
Please note that the sequence pictured above represents 40 minutes of showering. Showers began at 5:55 and ended at about 6:35. While the shower was running, the automatic clothes washer was also filling. The performance of the shower was not substantially affected. How do we know? Because the pressure gage shows that the system pressure stayed above 50 psi throughout the sequence.
People are creatures of habit so we can expect that the Well Manager® in this home will be refilled each morning at about the same time (7:42 AM). If it begins to take longer this is an indication of a change in the well. During times of drought, a system that takes longer and longer to fill indicates a diminishing water supply and the need for the residents to change the collection timing and possibly modify their water use.
