Nah, that's normal, especially with a new system or after a filter change. It's just dissolved air coming out of solution.
The water is under pressure in the tank. When you release it at the faucet, the pressure drops and tiny air bubbles form, making the water look cloudy or fizzy for a few seconds. It clears up in your glass.
If it's persistent, here's what to check:
- New system/filter change: It can take 24-48 hours of use for all the air to purge from the system. Just keep using it.
- Check connections: Ensure all tubing connections are tight, especially on the feed water line (red) and the faucet line (clear). A small leak can suck in air.
- Tank pressure: If the air bubbles are excessive and continuous, the air charge in the storage tank might be low. This requires a specific tank pressure check and recharge procedure; you might need to call for service.
If the bubbles are accompanied by a strange taste or the water flow is very slow, then you might have a different issue, like a clog or a failing membrane.
