An annual inspection of the system is a requirement of NFPA 11, chapter 7 and NFPA 25, table 8-2. More importantly, however, our service examines the working condition of the foam system, analyses the foam concentrate quality, recommends necessary maintenance and/or repair work and reports on the “ready” condition of the system. This provides the end user with the knowledge of the reliability of the system, should the need for activation occur.
If any alterations are made to the system after initial startup, a retest will be required.
Client Representative
Someone from your company should meet our representative at the job site. This person’s role will be to assist us as the tank installation is inspected, the tank is filled with concentrate, and your personnel are prepared for the test.

Water tests are performed first to establish the system’s proportioner demand. Then, the foam proportioning is tested and percent verified. After testing is completed, we will prepare service and test reports for you to distribute to the proper authorities. Once the tank is filled, our representative will review the procedures with interested personnel. The test may occur about one hour after the tank is filled. All individuals who wish to witness the fill and/or test should be present at that time.
Equipment Checklist
Testing will include the use of the fire pump, if any. Proper communication between the pump house, riser room and test area is essential for an effective test. In addition, you will need to provide sufficient personnel to open and close the valves.
