Grow1 Kinetic Air Vacuum Relief Valve - 3/4-in - 150 PSI

Protect Water Lines From Vacuum Siphoning - 3/4-in Fitting

When a water line drains or shuts off, a vacuum can form and pull dirty water or debris back toward the source or into emitters. A vacuum relief valve opens to let air in at that moment, so the line breaks the vacuum instead of siphoning. This Grow1 Kinetic Air Vacuum Relief Valve is rated to 150 PSI.

The 3/4-in size suits growers running mid-size irrigation or hydroponic water lines. It is sold individually, so a hobbyist can add a single valve and a commercial grower can order the count each zone requires.

Key Features & Benefits

• Vacuum relief function — admits air when line pressure drops, which helps limit siphoning.
• 3/4-in size — matches common mid-size water line fittings; check your thread type before ordering.

Who Should Use Grow1 Kinetic Air Vacuum Relief Valve

Anyone running irrigation or hydroponic water lines who wants to reduce the risk of backsiphoning, from home gardeners with a single zone to commercial growers managing several.

Frequently Asked Questions

Q: What does a vacuum relief valve do?
A: It lets air enter a water line when pressure falls below the outside air pressure. This breaks the vacuum that could pull water backward. It helps protect emitters and the water source.

Q: Where is it usually installed?
A: Vacuum relief valves are typically installed at a high point in the line, downstream of the supply. Follow your system layout and local plumbing requirements.

Q: Is it the same as a check valve?
A: No. A check valve blocks reverse flow, while a vacuum relief valve admits air to break the vacuum. Some systems use both.

Q: What does 150 PSI mean?
A: PSI means pounds per square inch, a measure of water pressure. 150 PSI is the pressure rating listed for this valve.

Q: Does one order include multiple valves?
A: No. It is sold each, so one order line is one valve.
