Zonecheck™ – Drain-Free Flow Switch Testing
April 6, 2026Quarterly sprinkler system flow testing can be disruptive—both operationally and in terms of water usage. For years, building owners and facility managers have sought more efficient methods to test their systems without unnecessary water discharge.
In addition to water conservation, there is increasing interest in minimizing system impact. Frequent fire pump starts, the introduction of fresh oxygen into piping systems (which can accelerate corrosion), and overall testing complexity are all valid concerns that affect long-term system reliability and maintenance costs.
Zonecheck™ flow switch testing units, UL / FM Approvals listed, provide a practical and effective solution. These units enable functional testing of waterflow switches through internal recirculation, eliminating the need for system drainage while still verifying proper device operation.
Available in sizes ranging from 2-inch through 8-inch, Zonecheck™ units are suitable for both new installations and retrofit applications. Grooved-end connections simplify installation and integration into existing systems.
Key benefits include:
- Elimination of water discharge during testing
- Reduced fire pump operation during routine testing
- Minimized oxygen introduction, helping mitigate internal corrosion
- Faster, cleaner, and more efficient testing procedures
