Watts 0068720 Valve

When you're dealing with thick insulation on modern hot water storage tanks, the Watts 0068720 (Series SL100XL) is the industry standard for reliable temperature and pressure protection. This 3/4" T&P relief valve features an extended shank design that effectively eliminates the need for extension nipples on tanks with up to 1-3/4" of insulation. Built with a durable bronze body and a stainless steel spring, this self-closing safety valve is ASME rated and CSA listed to ensure high-performance relief under critical conditions.

The Watts SL100XL-150-3/4 utilizes a sophisticated thermostat with special thermo-bonded coating to accurately sense temperature increases, initiating relief at 210°F. Rated for a heating capacity of 105,000 BTU/hr and factory set at 150 psi, this valve provides a dual-layer defense against catastrophic tank failure. It is technically identical to and serves as a direct replacement for LFSL100XL-150-3/4, SL100XL-3/4-150, and SL100XL-Z5-150. For contractors, the 3/4" NPT male inlet and female outlet allow for a direct, secure fit in residential and light commercial hot water heater applications.

• Extended Shank Design: Facilitates easy installation on new-generation water heaters without extra fittings.
• Emergency Protection: Automatic pressure relief at 150 psi and temperature relief at 210°F prevents hazardous tank buildup.
• Corrosion Resistance: Features a bronze body and a protective thermo-bonded thermostat coating for longevity in harsh water conditions.
• Verified Compliance: ASME Section IV and CSA (ANSI Z21.22) certified to meet strict building codes and safety regulations.
• High Capacity: Robust 105,000 BTU/hr rating makes it compatible with most standard residential gas and electric water heaters.

What is the difference between SL100XL and standard T&P valves?
The SL100XL features a 1-1/4" extended shank specifically to reach through thick tank insulation that would normally block a standard valve's inlet threads.

Can the Watts 0068720 be used as a primary operating control?
No, this is an emergency safety device only. It is designed to discharge water in over-pressure or over-temperature scenarios and should never be used to regulate system pressure during normal operation.

Is the Watts SL100XL lead-free?
While the prefix "LF" indicates lead-free models, the Watts 0068720 is often cross-referenced with the LFSL100XL series for replacement; however, always verify local code requirements regarding lead-free components for potable water systems.
