pipeline. The valve D is sampling valve.
c. Install the check valve in the outlet pipeline.

●If making a soldered copper installation, do all sweat soldering before
connecting pipes to the valve. Torch heat will damage plastic parts.
●When turning threaded pipe fittings onto plastic fitting, use care not to
cross thread or broken valve.
