Atwood part number or general description

[Brad Smith]

Would anyone have the part number for the backflow check valve for a 10 gal Atwood hot water tank? Or even just the thread size? I would like to only crawl intowards the back of the tank once to take it out and replace it. Is it brass or plastic?
I have an 2018 327RST.

The water heater check valves are pretty universal - no need for a part number. You just need to know the diameter. They come in plastic or brass... need I say which one you want?
