Netafim AV-Combo-075 Mini Combination Air Vent

Air vents are used to control the air in irrigation systems for proper watering an accurate measurement for flow and water meters.

Controlling the air in irrigation systems controls the water flow and the most efficient way to control air is by the proper use of air vents. Both the presence of air and absence of air can cause problems and damage to irrigation systems. Netafim provides air vents to discharge and admit air as required.Trapped air in pipes impedes water flow and can lower watering uniformity. It can also cause water hammer and damage to pipes and fittings. Air in pipes also produces inaccurate readings for water and flow meters. For reliable and accurate water measurement, flow meters require pipes to be full of water. The absence of air in pipes can trigger contaminates such as mud and dirt to be drawn into the piping system.

Received Damaged
They came three to a bag. One was broken. Sprinkler Warehouse did not respond to my request for resolution. The undamaged ones work well.

I have an AV Combo 075. Does this valve have to be installed vertically to work correctly?
Russ B on Aug 4, 2014
Some of my drip emitters stop working and I have been replacing the emitters, however when I cut the 1/4" tubing to replace the emitters(with the water on) there is always air in the 1/4" supply line. Will this Netafim air vent resolve the air in the line situation?
