1-1/2 T-455NL No-Lead Bronze Check Valve

The Legend Valve 105-447NL is a 1-1/2 inch in-line check valve built from no-lead bronze for potable water systems. It prevents reverse flow in residential and light commercial plumbing installations where lead-free materials are required by code. The IPS threaded ends connect directly to standard iron-pipe-size fittings without adapters.

Thermals noise and power draw

This mechanical valve has no electrical components, so it draws zero power and produces no audible noise during operation. Fluid pressure alone opens and closes the internal disc, making thermal output and energy consumption non-existent. There are no moving parts that require lubrication or external energy input.

Replaces worn swing or spring check valves

The unit upgrades older brass or leaded bronze check valves that no longer meet no-lead regulations or that have begun to leak from seat wear. The jump is worth it when a system must comply with current lead-free standards or when an existing in-line valve fails to hold back-pressure reliably. It does not suit applications needing a vertical-lift or flanged connection.

Questions about this item

How do I install the 1-1/2 T-455 NL IPS in-line check valve, and what orientation mistake should I avoid?

Install the valve with the flow arrow pointing in the direction of water movement; the common error is fitting it backwards, which blocks flow entirely.

What maintenance or replacement will the no-lead bronze check valve need over time?

The internal spring and poppet can wear or collect debris, so plan to inspect the seal annually and replace the valve if leakage or reduced flow appears.

What limit appears first on the 105-447NL during sustained high-flow use?

The 1-1/2 inch IPS bore sets the maximum flow capacity; sustained demand beyond that rating causes pressure drop and possible chatter.
