What is a Check Valve?
A check valve, also known as a reflux valve, bottom valve, or one-way valve, allows fluid (liquid or gas) to flow in only one direction. A one-way valve is a double-port valve, meaning its valve body has two openings: one for fluid to enter and another for fluid to exit.
Check valves are used at the intersection between public and private water supplies. They protect potable water from potential pollution and are an important component of water meters. Therefore, they make a valuable contribution to protecting potable water.
Is it necessary to install a check valve in the water supply system?
In the water supply system, whether a check valve needs to be installed depends on the system‘s specific design requirements and the actual use environment. Generally speaking, most water supply systems need to install a check valve, mainly to protect the water supply network and ensure water quality safety.
- Residential users: Installed behind household water meters to prevent backflow and protect water supply pipes.
- Industrial users: Used in industrial water meter systems to prevent factory water or production water from flowing back to the water supply network.
- Commercial buildings: Ensure that commercial users‘ water use does not affect the overall water supply system.
Why do you need to install a check valve?
- Prevent water backflow
In a water supply system, if the water pressure at the user end is higher than the pressure of the water supply pipe (such as the pressure increase caused by a high-level water tank or pump), the water at the user end may flow back to the water supply network. A check valve can prevent this backflow phenomenon.
Backflow may carry impurities, pollutants or substandard water, polluting the entire water supply system.
- Protect water supply facilities
Backflow can damage water supply equipment (such as pumps, valves, water meters, etc.), and a check valve can prevent the equipment from being impacted by reverse pressure.
- Meet regulatory requirements
Water supply regulations in many areas explicitly require the installation of check valves in water supply systems, especially public water supply systems, to ensure the safety of water supply networks.
