Gauge Calibration
We are now calibrating Mid-West Gauges!
It is the recommendation of Mid-West Instruments that backflow test kits should be tested for accuracy on an annual basis. There are several reasons that support this position:
1. Backflow prevention assemblies are mechanical devices that must be tested on an annual basis to insure that they are functioning properly. Backflow test kits are mechanical devices and should be treated in the same manner.
2. Backflow prevention assemblies have their performance degrade over time based on the water to which they are exposed. Backflow test kits are exposed to the same conditions as backflow prevention assemblies.
3. Backflow prevention assemblies must be tested by certified backflow technicians to insure accurate testing. A test kit of unknown accuracy would be equivalent to an untrained person testing a backflow prevention assembly.
