If the well pump in your Troy home starts and stops more often than it should, or taps sputter right after the pump kicks on, the pressure tank is a common place to look. Most home well systems use a small pressure tank with a rubber bladder or diaphragm separating air from water. The air side acts as a cushion that pushes stored water into the house. When that air charge drops, the tank fills with water instead, a condition called waterlogging, and the pump cycles on and off far too often.
What Waterlogging Looks Like
- The pump runs in short bursts, even when only a little water is being used.
- Pressure at the taps surges and then goes weak, especially during showers or laundry.
- The pressure gauge on the tank reads close to the pump start point almost as soon as the pump shuts off.
- The pump motor feels warm, or you hear it switching on at odd times.
Safety First
Well pumps run on electricity, and the tank holds water under pressure. Shut off power to the pump at the breaker before touching the tank, and close the valve between the tank and the house. If you are not comfortable working around wiring or pressurized plumbing, have a licensed well contractor do the check. Do not rely on a tank that is missing its gauge or shows visible damage.
Step One: Confirm the Pump Is Off and the Tank Is Empty
With the breaker off, open a nearby tap to relieve pressure in the system. Let the water run until it stops, which tells you the tank has drained. An air reading taken while the tank still holds water is misleading, so this step matters.
Step Two: Read the Air Pressure
Find the air valve on top of the tank. It looks like a tire valve and is usually under a small cap. Use a tire-style gauge to read the air pressure. Compare the reading to the pressure setting listed on the tank label or the pressure switch settings printed on the pump control box, not to what you remember. If the reading is well below the label, the air cushion has leaked or been lost.
Step Three: Look for Leaks and Failed Bladders
If you add air and the pressure falls back quickly, the valve core may be leaking or the bladder may have ruptured. Brush the valve with soapy water and watch for bubbles. If air keeps escaping, or water appears at the air valve when you check it, the bladder has likely failed and the tank may need replacement.
Why Troy Homes Should Also Test the Water
A pressure tank problem affects how water moves through the house, not what is in it. Private wells across rural Lincoln County are not regulated or tested under the Safe Drinking Water Act, and homes in and around Troy that draw from rock formations may carry naturally occurring minerals, bacteria, or other constituents. Once the pressure is steady, consider a separate water test, since a pressure fix will not show whether the water is safe to drink. Treat the two as separate projects.
When to Stop and Call for Help
- The pump keeps cycling after the air charge is set correctly.
- The tank shows rust, cracks, or water at the air valve.
- You cannot read the gauge or cannot isolate the tank from the house.
- Electrical parts, such as the pressure switch contacts, look burned or pitted.
Keep notes on what you checked and the readings you saw. That record helps any technician who comes out next.
