One unexpected condition that can impact water flowing through water mains serving our residences is……………air.
Water mains are not typically full of water and therefore there is air present. Air can build up in water mains, especially at high points, to the point that an air lock can occur. An air lock can result in pressure loss and even stop the flow of water.
A fairly easy way to prevent this is with an air vac. These components “burp” air when pressure builds to maintain good water flow.
Our employees recently installed a new air vac. One of the many jobs they do to keep our water system running smooth! Plus, who doesn’t enjoy a good burp!
