How to Inspect & Replace the Bladder in a Pressure Tank (Step-by-Step Guide)
Your pressure tank’s bladder plays a crucial role in maintaining water pressure and protecting your pump from damage. If it fails, your system will short cycle and may cause pump burnout. Here’s a step-by-step guide to inspecting and replacing it safely.
Signs of a Ruptured Bladder
Waterlogged tank with little air pressure
Rapid pump cycling
Air spurts from faucets
Visible rust or water leaks near tank base
Tools & Safety Equipment
Adjustable wrench
Tire pressure gauge
Air compressor or hand pump
Safety gloves & goggles
Teflon tape
Step-by-Step Process
1. Switch Off Power and Pump
Always turn off the breaker and shut off the pump to ensure safety.
2. Drain the Tank
Open the nearest tap and drain the tank completely.
3. Check the Air Charge
Use a tire gauge at the air valve — it should read about 2 psi below the pump’s cut-in pressure.
4. Inspect the Bladder
Remove the valve head carefully and check the bladder for ruptures, cracks, or signs of waterlogging.
5. Replace or Recharge
If replaceable, install a new bladder and reassemble.
If not serviceable, replace the entire tank to prevent future failures.
When to Call a Professional
If you find rust, leaks, or have difficulty with air pressure readings, contact a professional. A failed bladder can lead to expensive pump damage.

Q: How often should I inspect my bladder tank?
