TL;DR
A constant-pressure pump is a well pump system whose variable frequency drive speeds the motor up and down to hold household water pressure steady, typically within a couple PSI, regardless of how many fixtures run. It replaces the 20-PSI swing of a conventional pressure-switch system and needs only a small bladder tank instead of a large one.
What it means
A constant-pressure pump is a well pump system whose variable frequency drive speeds the motor up and down to hold household water pressure steady, typically within a couple PSI, regardless of how many fixtures run. It replaces the 20-PSI swing of a conventional pressure-switch system and needs only a small bladder tank instead of a large one. The trade-offs are a sensitive electronic drive that wants surge protection and a higher upfront cost, which is why quotes often present it alongside a conventional setup.
