Watts 0556032 Valve

The Watts 0556032 (Series LF3L) is a high-performance lead free pressure relief valve designed specifically for the protection of domestic storage tanks and tankless water heaters. This 3/4-inch poppet type relief valve serves as the direct updated replacement for the Watts 0011086, ensuring modern compliance with lead-free mandates. Constructed with a lead free copper alloy body and a corrosion-resistant stainless steel spring, it is factory set to 75 psi. While similar in architecture to the LF10L, this LF3L-075-3/4 valve is a pressure-only safety device, lacking a temperature relieving element, making it ideal for systems where independent pressure management is required. It features a manual test lever for routine maintenance and is certified under ANSI Z21.22 and ASME Section IV standards. This valve is frequently paired with LF210 gas shutoff valves to provide a comprehensive safety solution for residential and commercial hot water heater relief applications.

• System Protection: Automatically relieves excessive pressure to prevent catastrophic tank failure in domestic and tankless systems.
• Lead-Free Compliance: Features a lead free copper alloy construction that meets all current potable water regulations.
• Durable Internal Components: Equipped with a silicone disc and stainless steel spring for long-term sealing integrity and corrosion resistance.
• Standardized Fitment: Utilizes 3/4" MNPT (inlet) x 3/4" FNPT (outlet) connections for seamless replacement of the Watts 0011086.
• Certified Safety: Fully ASME rated and CSA listed, ensuring code compliance for professional HVACR inspections.

Is the Watts 0556032 a direct replacement for the 0011086?
Yes, the 0556032 is the designated lead free replacement for the obsolete 0011086 model, maintaining identical pressure settings and port sizes.

Does this valve protect against high temperatures?
No, the LF3L series is a pressure-only relief valve. For systems requiring temperature protection, it is typically used in tandem with a thermal shutoff or a dedicated T&P valve.

What is the maximum operating pressure for this valve?
The valve is factory-set to trip at 75 psi, though the series is rated for a maximum working pressure of up to 150 psi depending on the specific application environment.
