Grimac Pump Air Release Valve for Ulka Pump

Helps remove air pockets inside diaphragm pumps and assists with pump priming – air pockets sometimes prevent a diaphragm pump from priming or pumping water.
Additional hose to drip tray or water tank not included, but can be purchased at local hardware store or plumber’s supply at lower cost than we can provide.
Not a returnable item.
Technical support and instructions not included.
Please note that current stock does not have deadband adjustment as shown with offcenter smaller screw – in addition, the deadband adjustment if turned too much would render the pressurestat defective.
