Good morning LML,
Should be able to find it at Home Depot. It’s installed where hot water comes out of your water heater. To winterize you’d manually close the in-flow valve and drain the hot water heater. The check valve is supposed to stop the anti-freeze from back flowing into the water heater. If your installation has the space to do so, replace the check valve with a manual valve just like the other manual valve. It’s a tight space to work in and you’ll need your big wrenches.
In my limited experience the check valves have very poor quality and fail way too often. YMMV.
Regards,
