BAC Caution Tip

Many commercially available float balls are hollow with no foam filling and are not suitable for the rigors of evaporative cooling equipment. While operating, the inside of your equipment can resemble a hurricane with high winds and extreme temperature swings. Without the added structural rigidity from the foam filling, the float ball may easily crack, allowing the float to fill with water, which will cause the system to run improperly. Do not exceed 50 psi inlet water pressure to the float valve.
