On occasion the check valve on the micronizer will drip where the air is injected. The check valve is the only part that moves on a micronizer and it does so every time the pump runs.

Naturally, it can get worn out. These are very easy to replace:

• Turn the pump system off
• Remove the brass cap where air is injected
• Exchange the check valve
• Screw the cap back on

That's it!
