6 Best Well Pressure Gauges For Monitoring Well Health Old-Timers Swear By
Explore 6 time-tested well pressure gauges that experts trust. Learn how these durable models provide accurate readings to monitor your well’s health.
There’s a moment every person with a well dreads: you turn on the tap and get a weak, sputtering stream—or worse, nothing at all. Your mind immediately jumps to the worst-case scenario: a dead pump and a four-figure repair bill. But before you panic, the first place an old-timer will tell you to look is a small, unassuming dial on your pressure tank: the well pressure gauge. This little device is the single most important window into the health of your entire water system.
This durable 2.5" pressure gauge accurately measures 0-100 psi for water, air, and gas applications. Its glycerin-filled stainless steel case resists corrosion and vibration, ensuring clear readings and reliable performance.

Why a Reliable Well Gauge Is Non-Negotiable
A well pressure gauge tells you one simple thing: the water pressure inside your pressure tank. But that one piece of information is your primary diagnostic tool. It shows you the pressure at which your pump kicks on (the cut-in pressure) and when it shuts off (the cut-out pressure).
If that cycle becomes erratic, you know you have a problem. A gauge that never reaches cut-out pressure might indicate a failing pump or a major leak somewhere on your property. A rapid drop in pressure when no water is running points to a bad check valve or a leak in the house.
Think of it like the oil pressure gauge in a tractor. You could run without it, but you’d be flying blind, waiting for a catastrophic failure instead of catching a small problem early. A cheap, sticky, or broken gauge is worse than no gauge at all because it gives you false confidence. Investing in a reliable gauge isn’t an expense; it’s cheap insurance for your well.
WIKA 111.10: The Gold Standard for Accuracy
When you just need a gauge that works, period, the WIKA 111.10 is the one to get. It’s a "dry" gauge, meaning it isn’t filled with liquid. For most standard setups in a pumphouse or basement where vibration is minimal, this is all you need.
WIKA is a German brand known for industrial-grade precision, and that quality carries over to their basic utility gauges. The brass connection and copper alloy Bourdon tube (the internal part that moves the needle) are built to last. It’s a simple, robust, and incredibly accurate tool.
You won’t find fancy features here. What you get is a clear, easy-to-read dial that gives you a trustworthy reading every single time. For a straightforward well system, the WIKA provides professional-grade accuracy without the complexity or cost of more specialized gauges.
Winters PEM Series: Liquid-Filled for Durability
If your well pump causes a lot of vibration or your pipes tend to "chatter" when the pump kicks on, a dry gauge will get destroyed in short order. The needle will flutter wildly, making it impossible to read, and the delicate internal gears will wear out fast. The solution is a liquid-filled gauge, and the Winters PEM series is a classic choice.
These gauges are filled with glycerin. The thick liquid dampens vibrations, keeping the needle steady and protecting the gauge’s guts from getting shaken apart. This makes it far easier to get an accurate reading and dramatically extends the life of the gauge in a rough environment.
The Winters PEM is a workhorse. It features a tough plastic or stainless case, a brass connection, and a clear display that won’t yellow over time. If your gauge is mounted directly to a pump or a noisy pressure switch, going with a liquid-filled model like this isn’t a luxury—it’s a necessity.
Ashcroft 1009: Stainless Steel for Tough Jobs
Some well setups are in harsh environments. Maybe your pressure tank is in a damp, musty cellar or a well pit that gets humid and condensates. In these conditions, standard brass fittings can corrode and fail over time.
This is where the Ashcroft 1009 shines. It’s built with a full stainless steel case and stainless steel internals. This makes it exceptionally resistant to rust and corrosion, ensuring it will last for decades even in the dampest locations. It’s the kind of thing you install once and never think about again.
Of course, this level of durability comes at a higher price. An Ashcroft gauge is an investment. But if you’ve ever had to wrestle with a corroded, seized-up gauge that snaps off in the fitting, you understand the value of paying more for something that simply won’t fail.
DuraChoice PG25L: A Solid, Budget-Friendly Pick
You don’t always need the top-of-the-line option to get a reliable tool. DuraChoice has carved out a niche for making solid, dependable gauges that don’t break the bank. Their PG25L is a great example of a liquid-filled gauge that offers excellent value.
It has the features you need—a stainless steel case, brass connection, and glycerin filling for vibration dampening—at a price point that’s hard to beat. While it might not have the same brand prestige as a WIKA or Ashcroft, it’s a proven performer for general farm use.
This is the perfect choice for a secondary well, a system on a tight budget, or simply as a reliable replacement that gets the job done. It proves that you can get the benefits of a liquid-filled gauge without paying a premium price.
Watts LFPB3000: Lead-Free and Easy to Install
For anyone concerned about water quality, especially for drinking water for your family or livestock, a lead-free gauge is a smart move. Watts is a household name in plumbing, and their LFPB3000 series is designed specifically for potable water systems.
The "LF" in the model name stands for lead-free, meaning the wetted parts meet modern safety standards. Beyond that, it’s just a well-made, easy-to-read gauge from a company you can trust. They are built for plumbers, so the construction is solid and designed for a long service life.
Choosing a Watts gauge gives you peace of mind on two fronts. You know you’re getting a quality product from a major manufacturer, and you know you aren’t introducing any unwanted materials into your water supply. It’s a safe, reliable, and responsible choice.
Measureman 2.5-Inch: Best for High-Vibration
Some pumps are just plain violent. Older piston pumps or powerful submersibles can send a shudder through the entire plumbing system when they start and stop. For these extreme cases, you need a gauge specifically built to handle the abuse, and Measureman’s liquid-filled gauges are exceptionally good at it.
Like the Winters, these gauges are glycerin-filled to absorb the shock. However, Measureman has become a go-to for applications where vibration is the number one enemy. The needle remains rock-steady even when the pipe it’s attached to is visibly shaking.
This stability isn’t just for show. It prevents the premature wear that destroys lesser gauges. If you’ve had multiple gauges fail on the same system due to vibration, a Measureman is often the final, permanent solution to the problem.
Reading and Replacing Your Well Pressure Gauge
Your gauge should show pressure climbing when the pump runs and falling as you use water. The needle will stop at the "cut-out" pressure (e.g., 60 PSI) and the pump will turn off. It will then fall to the "cut-in" pressure (e.g., 40 PSI), at which point the pump turns back on. This 40/60 PSI range is very common.
Replacing a gauge is a simple but important job. Follow these steps carefully:
- Kill the power. Turn off the circuit breaker for your well pump. This is the most important step.
- Drain the system. Open a nearby spigot or faucet to drain all the pressure out of the tank. The gauge should fall to zero.
- Use two wrenches. Place one wrench on the pipe fitting the gauge is screwed into to hold it steady. Use the second wrench to unscrew the old gauge. This prevents you from breaking the pipe or fitting.
- Seal the new gauge. Wrap the threads of the new gauge with 3-4 layers of Teflon tape or apply a quality pipe thread sealant.
- Install and test. Screw the new gauge in until it’s snug and facing you. Close the spigot, turn the power back on, and let the system re-pressurize. Check carefully for any leaks around the new threads.
Your well pressure gauge is a small, inexpensive part of a very expensive system. Don’t treat it as an afterthought. Choosing a quality gauge and learning how to read it is one of the easiest steps you can take to protect your pump, diagnose problems early, and ensure you have reliable water when you need it most.
