What size?

...Is the water heater drain plug? Are they all the same?

There are all manner of packs of these floating around. Like THIS ONE.


Are those angled wrenches of any use? I'm thinking mine is going to need a socket extension to get to it.
  • After I drain our's the first time I replace the plug with a ball valve.

  • Clarification:

    Suburban Anode Rod Hex head requires 1 1/16" socket
    Drain hole is 3/4" NPT

    Atwood can be 2 different sizes depending on Vendor
    A 15/16" socket OR a 7/8" socket
    NYLON drain plug...both are 1/2" NPT

    X 2. one socket is best.

    skinny, wrenches will slip, and there seems to something in the way.
  • Yeah, I used a Sharpie and wrote "1-1/16" on it so I know which socket to grab when I want to remove on my Suburban anode/drain plug.

  • I like to use a 6 pointed socket. Too easy to round the corners off the Attwood nylon plug when using 12 points.
