Air Bubbles
Lots of air bubbles in a glass when filling from the system faucet is normal if the system has been recently installed or the filters and/or membrane have been replaced. The system will slowly purge the accumulated air with continued use. The time it takes to completely purge the air from the system varies with different water pressure, water properties and system usage. If you would like to purge the air more quickly after installing new filters and/or membrane, you can drain an additional 1-2 tanks after the normal flushing procedure before drinking water from the system.
