Mid-West Instrument has been producing Quality Backflow Test Kits for the past 30 years and been represented in Australia by CMC Technologies for the last 20 years. Model 845-3 and 845-5 Backflow are stocked in Sydney at CMC Technologies’ facility.

Previously, 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”!

The 845 Models come with 5 years manufacturer’s warranty.
The CMC142 Model is an alternative cost-effective option for backflow prevention and comes with 1 year manufacturer’s warranty.
