Backflow Test Kits

Backflow Test Kits

A backflow test kit is a device that is used to test that backflow prevention valves are not leaking. Backflow prevention valves prevent the unwanted flow of water in the opposite direction than it is intended to go. Backflow can occur in plumbing systems and can contaminate the water supply, so it is important to regularly test the backflow prevention valves (usually once per year according to regulations) to ensure the safety of the water. A backflow test kit typically includes a calibrated differential pressure gauge and a set of specialized valves on a connected manifold that in combination is used to measure the differential pressure across each non return valve of a backflow prevention device. This information can be used to determine if the device is allowing backflow to occur and enable the plumber or certified tester to then to take steps to correct the problem.

CMC Technologies is the sole and exclusive distributor for Mid-West Instrument in Australia and New Guinea. We have stocks of backflow test kits and are authorised by MidWest Instrument as their calibration and repair centre.

 

Mid-West Instrument Backflow Test Kits

Mid-West Instrument has been producing Quality Backflow Test Kits for the past 30 years and has been represented in Australia by CMC Technologies for the last 24 years. Model 845-3 and 845-5 Backflow test kits are stocked in Sydney at CMC Technologies’ facility.

The Mid-West® Instrument model 845 backflow prevention test kit is the culmination of their over 45 years of experience in the cross-connection control and backflow prevention field. The model 845 backflow prevention test kits are engineered out of materials that are compatible with water and not prone to galvanic corrosion as occurs in Aluminum body test kits. As a result, the useful life of properly cared-for 845s can be 25 years or more. The design features that make the model 845, “The Ultimate Backflow Test Kit” are the result of Mid-West® Instrument gathering information from professional testers and backflow prevention instructors. A shoulder strap for carrying and hanging, a line pressure gauge, all needle valve construction with replaceable soft seats, serviceable in-line filters in the hoses, and a practical toolbox carrying case make the 845 easy to use and efficient. It is available in 3-valve and 5-valve configurations to suit any tester’s preference. The Mid-West® Instrument model 845 backflow test kit has become the standard of the industry worldwide with sales in the USA, Canada, Australia, Europe, Israel, and even Antarctica with test procedures in four languages.

Previously, the 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”!
