Common Signs of a Well Water Tank Problem

Unstable water pressure as the pump cycles on and off. A pump that runs less than 30 seconds to pressurize the tank. A pump that cycles on and off frequently or remains running. Water leaks at the pressure tank.

What are the symptoms of a bad well pressure tank?

Bad Pressure Tank Symptoms
  • Frequent, widespread water pressure fluctuations.
  • Multiple faucets that spit water instead of providing a steady stream.
  • Clicking sounds that seem to come from the pressure tank.
  • Increasing electric bills due to a failing check valve, causing the well pump to run constantly.

What is the life expectancy of a well pressure tank?

A well pressure tank typically lasts between 5 to 15 years, depending on maintenance, water quality, and usage frequency. Key signs that a well pressure tank needs replacement include water pressure fluctuations, unusual noises, and visible leaks.

How do you test a well pressure tank?

Find your well tank's pressure gauge (usually small, black, round, and located at the bottom of the tank). Check to see how the tank's pressure cycling is configured—either on a high (40/60 psi) or a low (30/50 psi) cycle. You can check this by having your partner run cold water from a tap for a few minutes.

Common Pressure Tank and Well System Problems

Can I add air to my pressure tank without draining it?

To ensure the longevity and efficiency of your well pressure tank, there are a few simple steps you should take when adding air.

What happens when a well pressure tank goes bad?

As a result, water pressure drops and your well pump switches on and off frequently, causing high energy bills and additional issues. As such, you must replace the water tank, as a waterlogged pressure tank is irreparable.

How many psi should a well pressure tank have?

Most well tanks come set at 30/50. The cut-on pressure for the well pump is 30 psi, so the pressure of the tank should have a pressure of 28 psi. If your well tank is on a 40/60 pressure switch, your pressure setting should be 38 psi.

How to test a well pump without pulling it?

Can I run a well without a pressure tank?

Well pumps are still able to function without a pressure tank, but it's highly recommended to install a pressure tank because they increase the lifespan of your well pump. Well pumps aren't designed to operate rapidly or continually; when this happens, they tend to engage in something called water cycling.

How to test a bladder tank?

Disconnect electrical power to the pump. Drain the tank by opening the closest faucet. Check the tank's pressure by placing an air pressure gauge on the air charging valve on the top of the tank. Add air if the pressure is more than 2 psi below the pump cut-in pressure.
