Acuguage Drops The Model 521G Backflow Test Kit

After twelve years of production, Acuguage has decided to discontinue its Model 521 backflow test kit. Acugauge states that while sale of the Model 521G is up, sale of the Model 521 has dwindled over the last two years.

Steve Welles, Production Engineer, thinks that the reason for this is the fact that more and more water purveyors and jurisdictions are requiring backflow testers to record the inlet pressure at the backflow device assembly. Some municipalities have even re-designed their backflow field report to include space for recording both the inlet supply pressure and water meter number.

Since Acugauge Model 521G is already equipped with a high-pressure gauge, most backflow testers find it more practical to use this model as they can test the backflow assembly and read the inlet water pressure all in the same step, without having to use two separate gauges or make two separate connections. Not only does this method save the backflow tester's time, it also reduces equipment cost and maintenance.

Acugauge will continue to support the Model 521 backflow preventer test kit for an unlimited time, and will perform an upgrade to any Model 521 purchased within the last thirty days, for a nominal fee. To arrange this upgrade, simply contact Acugauge Backflow Test Kits at
