Water Nozzles are the first line of defense during firefighting and are one of the most important elements of a fire system. Their high cost and extreme usage conditions are the main reasons why frequent inspections, proper maintenance and protection should become a habit of the user.
Foams, saltwater and fresh water may occasionally contain gravel, rocks or other contaminants, so it is important to rinse the nozzle after each use. Some models, such as the Turbo Jet 2011, have a flush function, thus avoiding the need to open the ejector. Failure to do so may result in clogging or corrosion of the nozzle and consequent laminar flow disturbances. Inspections and periodic reviews are also important.
1. Read the operating instructions supplied by the manufacturer.
2. Make a visual inspection of the ejector.
3. Pay attention to damaged or missing parts.
4. If the head is loose, tighten it.
5. Check that the ball valve lever and handle have not been damaged after the last use.
6. In case of bending or breaking of the turning head, the element should be replaced.
7. Run the flow test.
If you are not sure whether the ejector is working properly, have her inspect by an authorized service center.
