Buying Guide
What should I consider when choosing a backflow test kit?
- Test scope: Decide between RPZAs, DCVAs, or broader testing coverage. Choose kits that explicitly support your target backflow assemblies.
- Portability vs. capability: If you travel to job sites, prioritize compact, durable kits with protective cases. For shop-based testing, larger kits with more accessories can be advantageous.
- Gauges and readouts: Digital displays and backlit screens improve readability in varied lighting. A capture function helps store readings without repeating tests.
- Hoses and adapters: Look for color-coded, durable hoses and a range of adapters to fit different valves and connections.
- Calibration and maintenance: Kits that ship calibrated save setup time. Plan for periodic calibration checks to maintain accuracy.
- Warranty and support: A longer warranty and reputable brand support can reduce total ownership risk on critical field gear.
