The heated water pumped through the pipes gets cooled once the exit valve /mixer valve is opened. This results in reduced pressure in the system. So there is chance that air gets sucked into the tubes from atmosphere that causes fluctuating water shower ; or the tubes and reservoir can collapse under suction pressure. To avoid this a by pass connection for water is given through a vacuum valve. This valve is set for a calculated pressure in the system. Whenever pressure falls below this value it opens and allows extra water to enter into the system and thus maintaining the pressure in the system.

What is the purpose of an anti-siphon valve on an outdoor faucet?
An anti-siphon valve on an outdoor faucet prevents water from flowing back into the main water supply, which helps to prevent contamination of the water system.
What is the purpose of an anti-siphon valve in a spigot system and how does it prevent backflow of water?
An anti-siphon valve in a spigot system is designed to prevent the backflow of water. It works by creating a barrier that stops water from flowing back into the main water supply, which helps to maintain the cleanliness and safety of the water system.
What would cause the heat not to work in 1998 Ford Contour Sport?
it could have a bad heater water control valve. the valve is controled by engine vacuum and the vacuum line to the water valve may have a leek or be broken In addition to the above it may have a thermostat stuck open, or a clogged heater core. Drain and flush the system, replace the thermostat, and install a 50/50 mix of anti-freeze and distilled water.
How does the anti syphon valve work?
An anti-siphon valve prevents backflow of water into the drinking water supply. It is typically installed above the highest point in the system and uses a one-way valve to allow water to flow in only one direction, preventing contamination. When water pressure drops, the valve closes to prevent backflow.
How does an anti-siphon valve work to prevent backflow in a plumbing system?
An anti-siphon valve works by using a one-way valve to prevent water from flowing back into the plumbing system. This helps to stop contaminated water from entering the clean water supply, reducing the risk of backflow and potential health hazards.
What is the purpose of a spigot anti-siphon valve and how does it prevent backflow in a plumbing system?
A spigot anti-siphon valve is designed to prevent backflow in a plumbing system by creating a barrier that stops water from flowing back into the system. This helps to maintain the integrity of the water supply and prevent contamination.
What is the purpose of an anti-siphon valve and how does it work to prevent backflow in a plumbing system?
An anti-siphon valve is used to prevent contaminated water from flowing back into the clean water supply. It works by creating a barrier that only allows water to flow in one direction, preventing backflow and ensuring the safety of the water supply.
What is an anti syphon-valve?
An anti-siphon (or, anti-syphon) valve is a device that prevents liquid from returning to the line from which it came if a siphon action occurs. An anti-siphon device is frequently required on outdoor irrigation systems to prevent possibly contaminated water to be drawn back into the water supply lines if water pressure decreases in the water supply line. An anti-siphon device is not the same as a check valve. A check valve allows flow in only one direction, and requires pressure to function. An anti-siphon valve opens to the atmosphere when there is reduced or no pressure in the line.

How can I replace an anti-siphon valve?
To replace an anti-siphon valve, first turn off the water supply to the valve. Then, unscrew the old valve and remove it. Install the new valve in its place and tighten it securely. Finally, turn the water supply back on and test the new valve to ensure it is working properly.
How does an anti-siphon spigot prevent water contamination in outdoor faucets?
An anti-siphon spigot prevents water contamination in outdoor faucets by using a valve that closes when water pressure drops, stopping water from flowing backward into the plumbing system and potentially contaminating the water supply.
What is Anti freeze valve?
It's a valve that can open an hydraulic circuit befor the water inside freeze.
