For over 30 years Mid-West Instrument has been producing Quality Backflow Test Kits. Our Model 830 has been a 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.
Continuing development led to the Model 845 which is available in 5-valve, 3-valve and 2-valve configurations, delivered to our customers in a spacious durable carrying case with external fitting compartments.
The development has continued… We are proud to introduce our upgraded Model 845-5 with a new manifold. We have a newly redesigned Manifold with hoses coming off the bottom with valves positioned on the front. This new designed allowed us to perfect the newest addition to our family of backflow test kits. Model 835…
Our New Model 835 blends the best of all Mid-West test kits, the newly designed 5-valve 845-5 mounted in our legendary Model 830 case. Tests can be performed with the gauge securely mounted in the case, or it can be quickly and easily removed when portability is an issue. These features alone make our New Model 835 stand out from the crowd.
We have also redesigned our already popular backflow website www.backflowtestkits.com for ease of use. You can learn about our backflow test kits, available accessories, order product, & locate one of our stocking distributors and service centers.
