Mid-West Instrument Model 830 provides the capability for testing all brands of reduced pressure principle, pressure vacuum breaker, and double check valve backflow prevention assemblies. It is capable of performing all known test procedures including those recommended by ASSE, AWWA, FCCC and HR-USC, and NEWWA.

The test kit features improvements developed over thirty years as the industry standard, including filters on all hoses, a compartment for storing various adaptor fittings and kit suspension chain, and a rugged, molded plastic carrying case with removable cover for ease of use.

Test procedures are laminated in clear plastic and stored in the lid of the test kit case.
