For a backflow prevention assembly tester to do their job professionally requires an accurate test kit. Test kits vary widely in their accuracy, reliability, and durability.  Test kits can contain gauges, which use bellows, diaphragms, or transducers. Gauge bodies can be made of plastic or brass or aluminum. They can have 2, 3, or 5 needle valves in the kit.   K.C. Calibration Lab., Inc., since 1962 has maintained a state of the art NIST gauge lab that can help assure your test kit is working properly. If the gauge needs repair or calibration or you need to buy items like hoses, adapters, strainers, or needle valves, we can help you.
