Well Pump Check Valve

Check valves and their function

What is a Well Pump Check Valve?

A well pump check valve is a type of valve that is installed in a well pump system to prevent backflow and ensure efficient water supply. It is designed to allow water to flow in one direction, from the well to the distribution system, while preventing water from flowing back into the well. This helps to maintain a consistent water pressure and prevents the well pump from running dry.

How Does a Well Pump Check Valve Work?

A good pump check valve works by using a spring-loaded disc that is designed to allow water to flow in one direction. When water flows from the well to the distribution system, the disc opens, allowing water to pass through. However, when water tries to flow back into the well, the disc closes, preventing backflow.

Why well pump check valves are important

Well pump check valves are an essential component in a water supply system, and they play a crucial role in ensuring a reliable and efficient water supply. Here are some reasons why well pump check valves are important:

• Prevents Backflow:  A check valve ensures that water flows only in one direction, from the well to the distribution system, preventing backflow and potential contamination.
• Maintains Water Pressure: This helps maintain a consistent water pressure, which is essential for the proper operation of plumbing fixtures and appliances.
• Reduces Wear and Tear on the Pump: This can extend the life of the pump and reduce the need for costly repairs or replacement.
• Prevents Water Hammer: Reducing the pressure surges that can cause damage to the pipes and fittings.

Dimensions of well pump check valve

Well pump check valve dimensions are usually described in inches. Common size ranges include 1 to 4 inches in diameter and 3 to 10 inches in length. When selecting a suitable well pump check valve, it is recommended to refer to the relevant TWT manufacturer’s specifications or consult us to ensure that the appropriately sized well pump check valve is selected.
