Frequently Asked Questions
What PSI should my well tank gauge read?
Most residential well tanks operate between 30 and 50 psi, with the cut-in and cut-out thresholds set on your pressure switch. The gauge on the tank should match that range, typically 40/60 or 30/50. Check the label on your tank for the factory pre-charge pressure. If your gauge shows a much higher value, the tank may be waterlogged.
How do I know if my well tank pressure gauge is bad?
If the needle stays at zero while water is flowing, or if it swings wildly during pump cycles, the gauge may be failing. Condensation under the lens can also hide true readings. Try tapping the glass once; if the needle moves erratically, it’s time for a replacement. Our guide on well pump kits for home can help you plan a full system upgrade.
Can I install a pressure gauge for well tank myself?
Yes, with basic tools. Shut off the power to the pump, drain the tank, and unscrew the old gauge using a wrench. Wrap the threads of the new gauge with seal tape and tighten it gently. Most 1/4-inch NPT gauges mount in minutes. Be sure to use a backup wrench on the tank fitting to avoid twisting the pipe.
What does glycerin filled mean in a pressure gauge?
Glycerin inside the case cushions the movement against vibration and pulsation, preventing needle flutter. This is especially helpful for gauges mounted on well tanks, where the pump cycles on and off repeatedly. It also helps prevent internal condensation, which keeps the dial readable in humid basements.
