Constant pressure well systems (VFD)
Even household pressure, or a drive that is already faulting. We quote after we see the well.

A conventional well slams the pump fully on, then fully off, every time the tank drains to the cut-in. Pressure at the tap swings. Showers go weak when someone flushes. A constant-pressure system uses a variable frequency drive (VFD) so the motor only runs as hard as the house needs. That is the job — not a gadget upgrade for its own sake.
When to call
- Pressure swings every time a fixture opens, or a tankless heater and multi-head shower fight the well.
- The existing VFD shows a fault (phase loss, transducer, overcurrent) or the pump hunts.
- The big pressure tank is waterlogged and the pump short-cycles — sometimes the honest fix is a tank, sometimes it is a drive.
- A low-yield well that you do not want to hammer at full speed all day.
What we do
We start with the electrical and the well, not a catalog page. Incoming power, grounding, motor amps, transducer reading, and how the well recovers. Then we tell you if a drive belongs here, if the motor can live with variable speed, or if you need a conventional control and a correctly sized tank instead.

Questions we hear before this job
What is a constant-pressure well system?
A variable frequency drive (VFD) speeds the pump motor up and down to hold a set pressure. A pressure transducer tells the drive what the line is doing. The pressure tank is usually small — it is not doing the cycling work a conventional bladder tank does.
Can you put a VFD on my existing pump?
Sometimes. The motor, wiring, and supply have to be compatible. A lot of older 2-wire pumps and worn motors are a poor fit. We check that on site before we sell you a drive.
Is this the same as a standard pump controller?
No. A conventional control box and pressure switch slam the pump on and off between two set points. Read the comparison on our VFD vs. standard pump controller guide, then call if you want this shop to look at yours.
