Buying Guide: What to Look for in a Pressure Tank Bladder
Compatibility with Your Tank Size
Most replacement bladders are designed for specific tank capacities, often 19 to 24 liters (about 5 to 6 gallons). Always confirm your tank’s total volume before ordering. A mismatch can lead to poor performance or damage. Products like the Pressure Tank Air Bag Rubber Bladder Fits 19-24L and the 19-24 Liters Pressure Tank Air Bag for Cold Hot are clearly labeled for this range.
Material Quality and Durability

Frequently Asked Questions
How do I know if my pressure tank bladder is bad?
Signs include rapid pump cycling (short-cycling), water hammer noises, or low water pressure. You can also tap the tank: a hollow sound near the top indicates proper air charge, while a dull thud suggests water has filled the air chamber due to a ruptured bladder. For more details, see our article on how a well pressure tank works.
Can I replace just the bladder in my pressure tank?
Yes, many pressure tanks allow bladder replacement. Products like the Pressure Tank Air Bag Replacement for 19-24L Tanks are designed for this purpose. Always check your tank model and ensure the replacement bladder matches the tank’s capacity and dimensions.
Do I need to pre-charge the tank after installing a new bladder?
Absolutely. Most manufacturers recommend inflating the bladder to around 25 psi (or 2 psi below the pump cut-in pressure) before turning on the water. Failure to pre-charge can cause the bladder to overstretch and rupture. Use a standard tire pump or air compressor on the tank’s air valve.
What size pressure tank bladder do I need?
Bladder size corresponds to the total tank capacity, not the bladder volume. Common sizes for residential systems are 19-24 liters (5-6 gallons). For larger homes or higher demand, tanks like the 30-gallon WaterWorker HT-30B may be more appropriate. Consult our well pressure tank sizing for help.
