Components Of A Pressure Vacuum Breaker

A pressure vacuum breaker consists of various components that work together to prevent backflow and ensure the safety of the water supply. Its main purpose is to protect against cross-contamination by creating a barrier between the potable water supply and any potential pollutants or contaminants.

Inlet

The inlet is a crucial component of a pressure vacuum breaker (PVB). It is the point of entry for water into the device from the main water supply. The inlet is typically found at the bottom of the PVB. Where it has a connection to the main water line. This ensures a constant flow of water to the PVB and allows it to function effectively.

Air Inlet Valve

The air inlet valve is responsible for allowing air to enter the pressure vacuum breaker. It is located at the top of the device.  When the design helps to prevent contaminants from entering the water system while allowing air to flow freely. This valve opens when the pressure in the system drops, which allows air to enter and prevent backflow.

Check Valve

The check valve is a vital component of the pressure vacuum breaker. It can be found between the inlet and the outlet and ensures that water flows in only one direction. This valve prevents backflow, which occurs when water flows back into the main water supply. The check valve ensures that the water can only flow out of the device to the desired location.

Outlet

The outlet is where the water exits from the pressure vacuum breaker. Then it flows to its certain location. It typically has a connection to the irrigation system of the whole house. The outlet lets the water to flow freely while preventing any backflow from occurring. It plays a crucial role in ensuring that the water is flowing properly. Also, ensure that it does not contaminate the main water supply. 

How A Pressure Vacuum Breaker Works

A pressure vacuum breaker is an important part of a water irrigation system, designed to prevent the backflow of water into the main water supply. Wondering what does a pressure vacuum breaker do? Let’s dive into understanding how it works.

Normal Operation

During normal operation, water flows through the pressure vacuum breaker. Creating a vacuum within the system along the stream. This vacuum draws air in through the air inlet. Disrupting the flow of water in the event of a pressure loss. The air inlet is key to ensuring the pressure within the system remains in proper balance. This allows the device to function effectively.

Backflow Prevention

The primary function of a pressure vacuum breaker is to prevent backflow. Backflow occurs when water reverses in the backward direction. Which flows back into the main water supply. This can happen due to a drop in water pressure, potentially causing contamination of the drinking water. The pressure vacuum breaker creates a physical barrier. This prevents the backflow of water and safeguards the purity of the water.
