Air Volume Control Guide
Find the right air volume control for your well system in two simple steps.
Step 1
What type of system do you have?
Deep Well / Submersible Pump
For conventional pressure tanks that need to release excess air.
Shallow Well / Jet PumpFor compatible conventional pressure tanks that need air charging.
Step 2
Choose the Right Air Volume Control
Compare the three deep well models, or choose SWL for a compatible shallow well system.
Keep Air and Water in Balance.
An air volume control valve maintains the proper amount of air in a conventional well pressure tank. Too much or too little air can cause problems with your water system.
Deep Well Systems
The control releases excess air from the pressure tank.
Shallow Well Systems
The control helps maintain the proper air charge in the tank.
Check your tank type. Air volume controls are designed for compatible conventional air-over-water tanks. Typical precharged bladder tanks maintain their air charge separately.
When to Replace Your Air Volume Control
Not sure if your air volume control valve is failing? Here are three signs to watch for.
Water Leaking
Water continuously leaks from the air volume control.
Air in Your Faucets
Your faucets sputter or spit air.
Pump Short Cycling
Your well pump turns on and off too frequently.
Before You Replace It
These symptoms can have other causes. Check your pressure tank and air charging system before replacing the control. A brief hissing sound from a deep well air volume control can be normal.
Air Volume Control Installation Made Simple
Replacing an air volume control valve? Follow these three basic steps, then use the full instructions for your specific model.
Step 1 Turn Off & Drain
Shut off pump power and safely relieve tank pressure.
Step 2 Replace the Control
Remove the old control and install the correct replacement.
Step 3 Restore & Check
Restore service, check for leaks, and verify operation.

Works like a charm.

Amazon ReviewMerrill air volume control valve
Was getting too much air in water pressure tank, this Merrill avcv fixed it right up. Only basic plumbing skills required and electrical if your pressure switch is attached to the same plumbing.

Worked as it should on my pressure tank.
Air Volume Control FAQs
Common Questions
Why is air coming out of my faucets?
Excess air in your well pressure tank can cause faucets to sputter or spit air. A faulty air volume control valve may be responsible, but other well system issues can cause this too.
Why is my air volume control valve leaking water?
A leaking air volume control valve may have a damaged float, worn internal parts, or debris preventing it from closing. Continuous water leakage may indicate the valve needs repair or replacement.
Why does my well pump keep turning on and off?
Frequent pump cycling can indicate a waterlogged pressure tank with insufficient air. A faulty air volume control or air-charging system may be responsible, but other issues can cause short cycling.
Is it normal for an air volume control valve to hiss?
Yes. A deep well air volume control valve may briefly hiss when releasing excess air from the pressure tank. This is often normal operation.
How do I adjust an air volume control valve?
Some air volume control valves are adjustable, while others are factory-set. Check your model's installation instructions before making adjustments to your well tank's air volume control.
What's the difference between deep well and shallow well air volume controls?
Deep well air volume controls release excess air from conventional pressure tanks. Shallow well air volume controls help maintain the proper air charge in compatible jet pump systems.
Do I need an air volume control valve for a bladder pressure tank?
No. Air volume control valves are designed for compatible conventional air-over-water pressure tanks. Most precharged bladder tanks maintain their air charge separately and don't require an air volume control.
Can I replace an air volume control valve myself?
Yes, some water well air volume control valves can be replaced without replacing the pressure tank. Follow the manufacturer's instructions, disconnect power, and safely relieve tank pressure before beginning.
