Backflow Test Kits

Mid-West Instrument Backflow Test Kits

The Mid-West Instrument Model’s 845-5, 845-3 and 845-2 have been added to both the FCCC & HR-USC and CA-NV AWWA list of Acceptable Gauges. The 845’s join the 830 on the list.

For the past 30 years Mid-West Instrument has been producing Quality Backflow Test Kits. Our Model 830 has been the benchmark of the industry for decades. Constant input from field testers led to refinements such as inline filters, laminated test procedures, removable lids, soft seated needle valves & line pressure gauges.

Further input testing and updated technology led to the portable Model 844. The culmination of all this development has resulted in Mid-West’s newest product offering, the Model 845. This new model features all the benefits you’ve come to expect from our kits and is available in 5-valve, 3-valve and 2-valve configurations. The addition of the Model 845 to our product lineup truly allows Mid-West to offer “A Test Kit for Every Preference”!
