3/4 in Brass Stop and Waste Valve
This valve controls water flow and provides a drain port for system maintenance. The brass body with FNPT x FNPT connections suits residential and light commercial plumbing. It meets ANSI B1.20.1, ASME A112.4.14, CSA B125.14, NSF/ANSI 372 and NSF/ANSI 61 standards.
Suits installers needing a drainable shut-off
The wheel handle allows manual operation and the 125 psi rating covers typical supply pressures. Installers who require a solder connection, a larger pipe size or a lever handle should select a different model. This unit is restricted from sale in certain states; verify local code acceptance before purchase.
Threads onto 3/4 in FNPT piping
The 2.95 in overall length fits standard rough-in spacing. Apply pipe thread sealant to the FNPT connections to prevent leaks. Over-tightening the cast iron wheel handle can strip the stem threads, so tighten by hand plus a quarter turn.

Questions about this item
What pipe threads does the 3/4 in IPS valve connect to?
The valve has FNPT x FNPT threads, so it connects directly to 3/4 in male NPT fittings on both ends.
Will the brass body and wheel handle withstand the same pressure and temperature as my existing copper supply lines?
The valve is rated for 125 psi and 140 Degrees F, matching typical residential copper system limits.
How can I verify the drain function operates correctly after installation?
Turn the wheel handle to the closed position, open the waste cap, and confirm water drains from the side port while the main line stays shut.
