Top 4 Signs Your Pressure Tank Might Be Failing (and What You Can Do About It)
A pressure tank is essential for keeping your water supply steady and your pump running efficiently. Over time, it can wear out — leading to both minor inconveniences and expensive repairs. Here are the four most common warning signs your tank might be failing, why they happen, and how you can fix them.
Frequent Short Cycling
If your pump turns on and off too often, sometimes every few seconds, that’s short cycling.
Why it happens: The tank isn’t holding enough air, or the bladder inside has ruptured.
Why it’s bad: This overworks your pump motor and drives up your electricity usage.
Water Hammer or Banging Noises
That loud bang in your pipes when you shut off a tap is called water hammer.
Why it happens: Inconsistent pressure causes the water to slam through the pipes.
Why it’s bad: Over time, it can damage fittings, joints, and even the pump.
Higher Electricity Bills
If your bills are going up but your water use hasn’t changed, your pressure tank could be to blame.
Why it happens: A faulty tank forces your pump to work harder and run longer.
Why it’s bad: This shortens pump lifespan and wastes energy.
Waterlogged Tank
A working tank contains both air and water, separated by a bladder or diaphragm.
Why it happens: If the bladder fails, the tank fills completely with water.
Why it’s bad: Without air pressure, the pump must run every time you need water.
What You Can Do
Test the Tank: Tap the upper part — hollow means air is present, dull means it’s waterlogged.
Check the Pressure Switch: Look for burnt contacts or loose wiring.
Call a Professional: If the bladder is damaged, replacement is usually the best option.
