Can a Pressure Tank Be Repaired? Expert Advice on Fixing Well Pressure Tanks

If you have a well water system, a properly functioning pressure tank is crucial for maintaining consistent water pressure throughout your home. However, like any component, pressure tanks can experience issues over time. The good news is that in many cases, pressure tanks can be repaired rather than replaced. In this article, we’ll explore the common problems that can arise with pressure tanks and discuss whether repairs are possible, regardless of the tank’s make, model, age, shape, size, or color.

Understanding Well Pressure Tanks

A well pressure tank is a key component of a well water system. It stores water pumped from the well and maintains pressure in the plumbing system. When water is drawn from a faucet or appliance, the compressed air in the tank pushes the water out, providing consistent pressure. The tank’s pressure switch activates the well pump when the pressure drops below a certain level, allowing the tank to refill.

Common Pressure Tank Problems

Several issues can arise with well pressure tanks, including:

Waterlogging: If the tank’s internal bladder ruptures, water and air can mix, causing the tank to become waterlogged. This results in fluctuating water pressure and the pump running more frequently.
Leaks: Leaks can develop around the tank’s fittings or along welded seams, leading to water loss and pressure issues1.
Corrosion: Over time, the tank’s interior can corrode, especially if the water has a high mineral content. This can cause the tank to fail prematurely.
Pressure switch failure: The pressure switch that controls the pump can malfunction, causing the pump to run constantly or not turn on when needed.

Can Pressure Tanks Be Repaired?

In many cases, yes, pressure tanks can be repaired. However, the extent of the repair depends on the specific problem and the tank’s condition. Some repairs, such as replacing the pressure switch or tightening fittings, are relatively straightforward and can be done by a skilled plumber. More complex issues, like a ruptured bladder or extensive corrosion, may require replacing the entire tank.

It’s important to note that while some tanks can be welded to fix leaks, this is not always a reliable solution, as the weld may fail over time. Additionally, using epoxy or sealants to patch leaks is generally not recommended, as these materials may not hold up under pressure and can potentially contaminate the water supply.

If you suspect an issue with your well pressure tank, it’s best to have it inspected by a professional plumber who can assess the problem and recommend the best course of action, whether that’s repair or replacement.
