The SHARKBANG Pressure Tank Air Bag is a rubber bladder replacement designed for 19 to 24 liter pressure tanks used with cold and hot water pumps. This product is ideal for homeowners or DIYers whose tanks have a failed bladder causing the pump to cycle frequently or lose pressure. Rather than replacing the entire tank, this affordable bladder restores normal function.
Standout features include its ability to keep water pressure stable inside the tank, which reduces the frequent start and stop of the water pump. This not only improves system efficiency but also extends the lifespan of the pump itself. The rubber material is flexible yet durable, suitable for both hot and cold water applications as noted in the product description.
Real-world performance from verified buyers shows it works well with common pump tanks like the Drummond 1 HP model from Harbor Freight. Users reported that after installation and proper inflation to around 23 psi, the bladder functioned correctly and stopped the pump from cycling. One reviewer successfully glued the flange to fix a leak, indicating that while the fit is generally good, some may need a little extra sealing effort.
However, there are a few drawbacks. Some customers found the bladder too small for their specific tanks, suggesting you measure your tank's internal volume carefully. Additionally, the bladder may arrive slightly deformed from packing; letting it sit around a similar-sized cylinder helped it regain shape. The product note also warns that the bladder must be inflated after installation, or water pressure could rupture it, so careful setup is essential.
Overall, the SHARKBANG Pressure Tank Air Bag is a solid, budget-friendly solution for reviving a failing pressure tank.

Buying Guide
Material Quality
The material of the bladder determines its durability and resistance to temperature and pressure. Most bladders are made from rubber or EPDM. Rubber bladders offer good elasticity and sealing, while EPDM bladders are more resistant to high temperatures and ozone, making them suitable for hot water systems and solar applications. For drinking water, look for food-grade EPDM or PE materials.
Compatibility with Tank Size
Most replacement bladders are designed for 19-24 liter pressure tanks, which is common for residential well pumps. Always confirm that the bladder fits your tank’s total capacity, not the bladder volume. For larger systems like the 100L vertical tank, you need a specialized part. Refer to our well pressure tank sizing to ensure the right match.
Sealing and Leak Prevention
A good bladder must provide an airtight seal to maintain pressure separation. Look for integrated molding or reinforced seams that prevent leaks. Products with high user ratings and verified sealing performance, like the SHARKBANG and FurnyQuaint options, are reliable choices.
Ease of Installation
Most bladders are designed for direct replacement without special tools. However, it is critical to inflate the bladder after installation to avoid damage. Some models include a pull ring for easier handling. Check the product description for installation notes. For more details on pressure tank components, visit our pressure tanks category.
Final Thoughts
Choosing the right bladder for well pump restores stable water pressure and prevents pump damage. For most 19-24L tanks, the 19-24L Pressure Tank Air Bag Rubber Bladder Well from Wavexa offers OEM-standard fit and industrial-grade durability. If you need a food-grade option for hot water or solar systems, the EPDM Expansion Tank Bladder 19-24L Pressure Tank from WLSANX is an excellent choice. Both provide reliable performance and easy installation.
Frequently Asked Questions
How do I know if my well pump bladder needs replacing?
Common signs include rapid pump cycling (short-cycling), water pressure fluctuations, and air sputtering from faucets. If your pressure tank feels waterlogged or the air valve leaks water, the bladder is likely ruptured.
Can I replace the bladder without removing the tank?
In most cases, yes. You can replace the bladder by removing the flange on the tank. Ensure the tank is depressurized and drained first. Follow the manufacturer’s instructions and inflate the new bladder before use.
What size bladder do I need for my well pump?
Bladders are sized to match the total tank capacity, not the water volume. Most residential tanks are 19-24 liters (5-6 gallons). Check your tank’s label or measure its dimensions. For larger tanks, see our pressure systems guide for sizing advice.
How often should I replace the bladder in my pressure tank?
Bladders typically last 5-10 years depending on water quality and usage. Regular inspection every 2026 can catch early signs of wear. Replace it at the first sign of failure to avoid pump damage.
