The Clean Water Act serves as the EPA's foundation for protecting the environment and public health. This Act prohibits all chlorinated swimming pool discharges and filter back-flushing without dechlorinating the water prior to discharge.

The Bazooka is designed for easy dechlorination during hydrant flushing.


  • Attaches directly to a 2½”, 4” or 4½” fire hydrant fitting.


  • Comes in two configurations: tablet and liquid chemical feed.


2 ½” size Bazooka set up for liquid chemical feed.


2 ½” size Bazooka, feeding sodium sulfite or ascorbic acid tablets (Vitamin C) for dechlorination.



From the open hydrant valve, water passes through the unit creating a vacuum which pulls the dechlorinization chemical from its supply container into the system via the rotometer rate valve assembly. The rotometer rate assembly provides precise control of the dechlorination solution strength to avoid chemical waste or over dechlorination.



By opening the hydrant valve, a small amount of water is bypassed from the pressure side of the Bazooka venturi to the rate valve flowmeter assembly and supplied to the bottom of the tablet chamber dissolving the tablets in a precise manner. The dechlorination solution is then pulled into the system, making a homogeneous mixture proportioned and controlled to ensure that all water is in contact with the correct amount of chemical. Adjusting the flowmeter setting provides precision chemical control to avoid chemical waste or over dechlorination.


Typical hydrant flushing application using the truck mounted diffuser.
