Test cock for backflow preventers

The Watts LF-TC 757/957 test cock fits 3/4 inch NPT connections on compatible backflow prevention assemblies. It provides a dedicated port for pressure testing and system diagnostics during installation or annual certification. The bronze construction suits potable water and standard hydronic applications.

Straightforward NPT installation

Thread the cock into the designated test port using standard pipe sealant to ensure a leak-free seal. The 3/4 inch NPT sizing matches the specified Watts series ports directly. Over-tightening bronze fittings can strip threads or crack the body, so hand-tight plus one turn is the typical practice.

Rated for ANS and ASME A 112.1. 2 systems

This component meets the listed standards for backflow preventer test cocks in plumbing installations. It handles the pressure ranges encountered in normal testing procedures for the 757 and 957 series assemblies. It is not a shut-off valve and must not be used to isolate flow in live piping.

Questions about this item

How can I confirm the test cock is operating correctly after installation?

Verify proper operation by checking for leak-free connections at the NPT threads and confirming the valve opens and closes smoothly during backflow preventer testing procedures.

What components are included with the test cock and what additional items are needed for installation?

The package contains the bronze test cock with 3/4 inch NPT connection; pipe thread sealant and appropriate wrenches for NPT fitting installation must be purchased separately.

Which version should I select between the LF-TC 757 and 957 models for my backflow preventer?

Both model numbers 757 and 957 are referenced for this 3/4 inch test cock; choose based on the specific Watts backflow preventer series compatibility requirements for your installation.
