Watts 0385496 Tester

Professional field testing of backflow prevention assemblies requires precision equipment that holds up to the rigors of the job site. The Watts 0385496 TK-9A Backflow Preventer Test Kit is the industry standard for verifying the performance of Reduced Pressure Zone (RPZ) assemblies, Double Check Valve Assemblies (DCVA), and Pressure Vacuum Breakers (PVB). Engineered for backflow testing compliance with ASSE 5000 and USC standards, this analog backflow tester features a clear 4-1/2 inch face with a dual-scale 0-15 psid range. The Watts TK-9A utilizes two high-quality ball valves and a precision needle valve for fine-tuned metering, ensuring accurate diagnosis of zone differential pressure and relief valve opening points. Built for the service truck, the Watts 0385496 is housed in a shock-resistant case and includes color-coded hoses with swivel couplings to streamline backflow preventer test procedures. Whether you are troubleshooting fouled check valves or performing annual certifications, this compact kit provides backflow assembly diagnostic accuracy within +/- 2% full scale.

• Precision Metering: Equipped with a dedicated needle valve for exact readings and two durable 600 psi ball valves for reliable isolation.
• Rugged Durability: Weatherproof gauge design and shock-resistant molded plastic case with foam inserts protect internal components on-site.
• Efficient Setup: Includes three 3-foot color-coded hoses and a comprehensive adapter set (1/4", 1/2", and 3/4" bushings) to fit any testable assembly.

Common Questions

Is the 0385496 a direct replacement for the older TK-9A?
Yes, the 0385496 is the specific order code for the Watts TK-9A tester. They are functionally identical units used for standard field testing applications.

What is the maximum operating pressure and temperature for this kit?
The unit is rated for a maximum working pressure of 175 psi and can handle temperatures up to 210°F, making it suitable for both cold and hot water systems.

How do I verify relief valve opening differential?
By connecting the high and low-side hoses to the appropriate test cocks and slowly opening the needle valve, you can accurately observe the gauge reading at the exact moment the relief valve discharges.
