Tankless Valve Kit for Water Heaters
The Legend Valve 101-154NL is a 3/4-inch sweat connection valve kit designed for tankless water heater installations. It includes a pressure relief valve rated for 200K BTU capacity. The lead-free brass construction meets no-lead plumbing standards for potable water systems. This kit suits plumbers and contractors completing new or replacement tankless heater hookups.
Replaces Separate Valve Assemblies
This single kit consolidates the isolation valves and pressure relief components normally sourced as individual pieces. The integrated design reduces the number of joints that must be soldered or threaded during installation. The jump is worth it when a faster, code-compliant rough-in is required on a tankless unit. It is not for installations that require flanged or threaded connections instead of sweat ends.
Sustained High-Temperature Operation
The valve body and PRV are built to handle continuous hot water flow at the rated 200K BTU output without degradation. The pressure relief mechanism maintains consistent discharge performance over repeated thermal cycles. California Proposition 65 warnings apply to chemical content in the brass components. The kit is not for steam service or applications exceeding the stated BTU rating.

Questions about this item
What pipe size does the 3/4" FNPT union on the 101-154NL kit require?
The kit uses a 3/4-inch female NPT union that threads onto matching male NPT pipe threads.
Which step is often missed when sweat-soldering the NL connections on this valve kit?
Clean and flux both copper tube and fitting, then apply heat evenly before feeding solder into the joint.
How often should the 200K BTU pressure-relief valve be tested or replaced?
Test the relief valve lever annually; replace the valve if it leaks, fails to open, or shows corrosion.
