If you’re experiencing issues with your well pump, it’s important to identify the problem as soon as possible to avoid any further damage or inconvenience. One of the most common issues with well pumps is a faulty check valve. In this article, we’ll explore the signs and symptoms of a bad well pump check valve and what you can do to diagnose and replace it.

Signs of a Bad Well Pump Check Valve

A well pump check valve is designed to prevent backflow and ensure that water flows in only one direction. If the check valve is not functioning properly, it can cause several problems, including:

  1. Water flowing backward: If water is flowing backward through the system, it’s a clear indication that the check valve is not working correctly.
  2. Sump pump running constantly: If the sump pump is running constantly, it’s a sign that the check valve is not able to prevent backflow.
  3. Water hammer: Water hammer is a common problem that occurs when the check valve is not functioning properly. It’s characterized by a loud banging noise in the pipes.
  4. Reduced water pressure: If the water pressure in your home is low, it could be a sign that the check valve is not working correctly.
  5. Air in the water line: If there’s air in the water line, it’s a sign that the check valve is not able to prevent backflow.
