Black Tank Vacuum Breaker Check Valve

[JohnDar]

All, While inspecting the plumbing behind the basement wall, I discovered the rectangular plastic "cap" from this check valve, sitting on top of the water heater! The tabs that hold it in place appeared to be broken, and the cap has been sitting in this location probably since build date, as there was caked sawdust in it. Do we need to figure out how to get to it in the wall and see if it was replaced or if we need to fix?

If you have a round access port in your shower wall, try looking in there. Maybe you'll be lucky and they installed it there where you can get at it. If not, and it's broken, when you run the tank flush, watch for water coming down the wall or along the PEX lines to it.

Thanks John, I don't recall us having water issues there, but we'll check again. The Elk Ridge doesn't have the shower surround with a round access port, but possibly we can look behind the plastic panel that the shower faucet is mounted to... it has 4 screws to remove it.
