It installs on the tank and works in conjunction with a submersible pump to prevent waterlogging by ensuring adequate air cushion volume is preserved during pump cycles. The unit is built with metal construction for durability in wet mechanical environments. It ships with 48 inches of poly tubing and fittings included for a complete installation. This part is intended for plumbers and pump service technicians working on residential or light commercial well water systems.\u003c\/p\u003e\u003cp\u003eThis air volume control is used specifically with galvanized pressure tanks paired with submersible pumps in shallow well applications. It is not compatible with pre-charged or bladder-style pressure tanks, which do not require external air volume management. Typical installations involve residential well systems where the pressure tank lacks an internal diaphragm or bladder and relies on a captive air charge maintained by the control. The included poly tubing simplifies the connection between the control fitting and the tank air port.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMaintains correct air-to-water ratio in galvanized pressure tanks\u003c\/li\u003e\n\u003cli\u003eCompatible with submersible pump systems in shallow well configurations\u003c\/li\u003e\n\u003cli\u003eMetal construction for durability in pump house and utility environments\u003c\/li\u003e\n\u003cli\u003eIncludes 48 inches of poly tubing and fittings for complete installation\u003c\/li\u003e\n\u003cli\u003eNot for use with pre-charged or bladder pressure tanks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with submersible pumps and galvanized pressure tanks in shallow well water systems.

Shut off power to the pump and relieve all pressure from the tank and supply line before beginning work. Follow local plumbing codes and manufacturer guidelines when connecting the poly tubing to the tank air port. Do not use this control on bladder or diaphragm-type pre-charged tanks.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.3 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: 48 inches of poly tubing and fittings\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction\u003c\/strong\u003e: Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ASHLAND WATER GROUP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: AV-56\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASHLAND","offers":[{"title":"Default Title","offer_id":51523359605042,"sku":"AV-56","price":102.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3fbbc0cf705f7181692a0a5068677f27.jpg?v=1785440672","url":"https:\/\/voomisupply.com\/products\/ashland-water-group-av-56-air-volume-control","provider":"Voomi Supply","version":"1.0","type":"link"}
