Everflow Supplies Inc. 210C114-NL SWT Swing Check Valve

1-1/4" Cast Brass Swing Check Valve

The Everflow 210C114-NL is a swing check valve built from heavy duty cast brass for residential and light commercial plumbing. It stops reverse water flow in potable and non-potable lines. The brass hinged disc opens under forward pressure and seats tightly when flow stops. Installers who need a reliable backflow preventer for copper sweat connections will find it fits the task.

Lead Content and Proposition 65 Compliance

This product contains lead and other chemicals listed under California Proposition 65 as known to cause cancer and reproductive harm. The regulation requires a clear warning at point of sale and on the product. Handling the valve exposes the user to lead, so washing hands after installation is necessary. Buyers who need a lead-free certified valve for drinking water systems governed by strict lead-free statutes cannot use this model.

Sweat Connection for Copper Pipe

The valve uses a sweat (SWT) inlet and outlet sized for 1-1/4" copper tubing. Joints are made by soldering directly to the valve body, creating a permanent, leak resistant seal. This connection method suits installers working with rigid copper pipe who prefer soldered joints over threaded or press-fit alternatives. Systems using PEX, CPVC or steel pipe without appropriate transition fittings cannot connect directly to this valve.
