Legend Valve 115-314NLS 3/4" Adapter

This Legend Valve adapter is a 3/4 inch sweat fitting designed for thermostatic mixing valve installations. It connects directly to copper piping without a check valve mechanism. The transparent finish allows visual confirmation of flow. It suits plumbing professionals completing bathware rough-in work.

Installers needing a non-check valve sweat

This part fits systems where a separate backflow preventer is already installed or not required by code. It is not for installers who need an integrated check valve in the same fitting. Buyers requiring threaded, press or push-fit ends should select a different model. The sweat design demands soldering tools and skill.

3/4 inch sweat connection without check valve

The defining specification is the 3/4 inch sweat adapter body combined with the absence of a check valve. This determines compatibility with the valve body and the piping layout. California Proposition 65 warnings apply to chemicals in the product materials. Verify local code acceptance for non-check configurations before purchase.

Questions about this item

Does the 115-314NLS valve meet California Proposition 65 requirements?

The product carries a Proposition 65 warning for chemicals known to cause cancer and reproductive harm, so it does not meet the requirement for a warning-free installation.

Will the brass body of the 115-314NLS overheat during continuous hot-water circulation?

The valve is designed for standard thermostatic mixing duty; the brass construction dissipates heat normally and no special cooling is required for all-day operation.

What piping and tools are needed to install the 115-314NLS sweat adapter?

You need 3/4-inch copper pipe, flux, lead-free solder, a propane torch, and two adjustable wrenches to complete the sweat connections on this adapter.
