Rv Fresh Water - Drain Water

In-line check valve provides a watertight seal with 1/2" MPT threading on both ends, giving your RV water line an ideal inline backflow preventer. Innovative hex design concept allows it to be installed with a 20mm deep well socket or wrench.

Replace the leaking check valve in your RV's fresh-water system to prevent backflow and keep antifreeze from leaking into your water heater. Brass construction won't rust. Valve has both 1/2" MPT and 1/2" FPT ends.
