Shaw explained this air volume control or AVC was intended as a deep well device - by this he probably meant not shallow or "dug" wells. Eventually the water tank will become water logged and the well pump or lake pump will cycle on and off rapidly when water is run in the building. Rather, if the snifter valve stops admitting air into the piping system OR if the drain-down valve becomes clogged and stops draining water out of the water piping, then because air isn't entering the piping no air is being pushed back up into the bladderless pressure when the pump runs. The float movement allows air into or out of the water pressure tank as needed.

If the air volume control is not working on a drain-back system, because each pump on cycle is pushing a lot of air into the water tank you will ultimately see air spurting out of the building's plumbing fixtures such as faucets. We will be in touch. Maintains proper relation of volume of air and quantity of water in the pressure tank. Plastic Shallow Well Air Volume Control is rated 4.0 out of 5 by 1. An "automatic" air volume control (AVC) device may be installed on the water pressure tank if it's an older, bladderless steel tank. 0000008408 00000 n This valve includes a low-pressure valve stem core that will open to admit air into the valve at about 10 psi. $19.98. 2 interesting notes: One well I have makes water with much air in it, and so the tanks never water log without any air maker. Gauge Type WJ - so we know this installation is for a deep well. Type wj for deep well. 81 0 obj <> endobj An excerpt is below. This short cycling is hard on the pump, and air is added to the tank to correct the situation. When water level falls inside the pressure tank to a level below the valve and its float, the valve opens, bleeding excess air out of the pressure tank. Where is it? In reverse, pressure inside the system pushing against the valve stem core closes the valve when its center pin is not depressed. The job of the AVC is to keep air in the water tank to avoid waterlogged water tanks or well pump short cycling.

Shallow Well Air Volume Control - No. Watch out: short cycling can still occur on a drain-down (bleed-back) system too, but not because the AVC isn't working. California Proposition 65 Warning at WATER TANK AIR VOLUME CONTROL REPAIR . to the tank, or perhaps on the side of the tank with a plastic or copper tube connecting the disc to a fitting on the tank or nearby piping, this is the AVC.. Used on jet pump water supply systems, on each pump "on" cycle the AVC draws in a small volume of air that is then pushed onwards into the water pressure tank. 0000001862 00000 n 0000003772 00000 n 0 The Schrader valve, Brady Valve, Dill valve ( different companies) consists of an externally and internally threaded metal stem. At DRAIN BACK / SNIFTER VALVE TROUBLESHOOTING we detail how the AVC is tested on a drain-back system or bleed-back system is tested to see if it is in fact releasing excess air as it should. Recapping, both types of these air volume controls are used only on bladderless water pressure tanks - tanks that do not use an internal bladder. Details about how to inspect & test the AVC to determine if it is working to keep a proper air charge in the water tank are. 0000149083 00000 n “Static” is what determines the pumps needed. does not become lost by absorption into the water. We describe what AVCs look like, we explain the types of air volume controls used on jet pumps and on submersible pumps, and we describe where to find them, and how these devices work, and how they can be repaired, replaced or just abandoned. It is used with submersible pumps. If you convert from a non-bladder type water pressure tank to a water tank using an internal bladder, part of that installation will include the removal of any air volume control valves on the system, including an AVC that may be mounted on the well pump (above-ground jet pumps) or a hidden AVC that is found inside the well piping (submersible well pumps only). 0000001646 00000 n If a water tank loses its air charge it stops working properly and usually results in This condition, in turn, can damage Bladder type water tanks do not use an air volume control valve: Air volume control valves are present only on steel water tanks which do not include an internal bladder Defective air volume control 3. Watch out: if on a submersible well pump system that uses a snifter valve for air volume control you later convert a bladderless water pressure tank to a tank using an internal bladder, you should remember to remove both the snifter valve located on the check valve near the water pressure tank and the bleeder orifice or drain-back valve located on the well piping. The air volume control or "AVC" device mounted (usually) on older steel water tanks (ones that do not use Skip to main content.sg. 0000009157 00000 n These devices do not work in an identical fashion, so buying the wrong model for your well would be a mistake.

On some water storage tanks such as the antique 450-gallon tank shown at left (courtesy of reader Craig Revill), the air volume control may not be so obvious (photo below right). Industry's Largest Selection of Air Volume Controls. The device was intended to be mounted in the wall of a water storage tank (as above) and adjacent to the water level in the tank so that the valve could respond to both air pressure and the water level in the tank itself. Gauge AVC + Gauge unit illustrated here from the company's product literature, incorporates a float inside the water tank. Using a US Gauge Type WJ or similar air volume control to manage air in the water pressure tank is a different approach that is unfamiliar to so many homeowners that we've seen some odd advice like "take off the part and throw it away" - which is usually not a good idea.
