If you need to refill your bubble counter often than once per week. Please make sure to check all connection between diffuser and bubble counter. If you have a leak, the pressure will escape and due to low resistance water will be pushed out of the bubble counter.
If you can't find any leaks, please make sure your working pressure is not higher than what your diffuser requires :
10-20PSI - Reactors
20-30PSI - Ceramic and Basic diffusers
30-40PSI - High pressure atomizers (inline & bazooka)
40-60PSI - Multiple outlets with high pressure atomizers (inline & bazooka)
When the working pressure is much higher than your diffuser resistance on each solenoid cycle water will be pushed out of the bubble counter's chamber.
