CONSTANT PRESSURE & VARIABLE SPEED SYSTEMS
Constant Pressure & Variable Speed Well Systems
Steady, strong water pressure no matter how many faucets are running. We install and upgrade constant pressure systems that keep your water pressure consistent — even when the whole house is using water at once. Family-owned and licensed, serving the Sacramento Valley.
What Is a Constant Pressure System?
A conventional well setup runs the pump full-blast until the pressure tank fills, then shuts off — so your pressure rises and falls as the pump cycles, and it drops noticeably when more than one fixture is running.
A constant pressure system uses a variable speed pump that adjusts its speed to match how much water you're using. Instead of cycling on and off, it ramps up and down automatically to hold your water pressure steady — whether you're running one faucet or five.
Signs a Constant Pressure System Is Right for You
-
Your water pressure drops when someone else turns on a faucet, shower, or the sprinklers
-
You have a two-story or larger home where pressure struggles upstairs
-
Multiple fixtures run at once and the pressure can't keep up
-
You're building or remodeling and want steady pressure from day one
-
Your conventional pump cycles constantly and you're tired of the swings
If your pressure problem is actually a failing pump or a waterlogged tank, that's a different fix — see our Well Pump Repair & Replacement and Pressure Tank pages, or just call (530) 565-3871 and we'll tell you which one you need.
The Benefits of Constant Pressure
Steady Pressure, Always
Your pressure stays consistent no matter what's running, so no more drops mid-shower when someone starts the dishwasher.
Every Fixture at Once
Run showers, faucets, and irrigation at the same time without the pressure falling off.
Better for Larger Homes
Two-story and larger homes get strong, even pressure on every floor and every fixture.
Smoother Operation, Less Wear
Because the pump ramps up and down instead of slamming on and off, the system runs quieter and cycles less — easier on your equipment.
A Cleaner Setup
Variable speed systems need only a small tank instead of a large conventional pressure tank, freeing up space and simplifying the system.

Constant Pressure FAQs
What is a constant pressure system?
It's a well system built around a variable speed pump that adjusts its speed to your water use, holding your pressure steady instead of letting it swing as the pump cycles on and off.
How is it different from a regular well pump?
A conventional pump runs at one speed and cycles on and off, so pressure rises and falls. A variable speed pump adjusts continuously to keep pressure constant, even when demand changes.
Will it fix my low water pressure?
If your pressure drops or fluctuates because of a conventional pump-and-tank setup or high demand, a constant pressure system delivers steady pressure. If the cause is a failing pump or a well that's low on capacity, that's a different fix — we'll diagnose it first.
Can I upgrade my existing well to constant pressure?
Yes. We retrofit conventional well systems with constant pressure and variable speed setups.
Do I still need a pressure tank?
A constant pressure system uses a much smaller tank than a conventional setup. We size and install the right components so it runs correctly.
Is it worth it for a two-story home?
Especially so. Larger and multi-story homes are where steady, even pressure on every floor makes the biggest difference.
