We have an Atwood Water Heater and are trying to remove the white nylon plug to drain and winterize. What size socket do we need? Can't seem to find the correct size. Thank you
My trailer is covered and winterized. I know I use a socket also...I'm thinking I used a 1/2'' drive extension too, plug might be either 13/16, 7/8 or 15/16... it's a little more than a guess because I really can't check my water heater plug know. Mike

Can't seem to find the correct size. Thank you I keep a spare plug for my Atwood water heater in my tool kit and it is 7/8". I use a 1/2" drive with an extension bar.
Eventually those plastic plugs get stripped on the head and in the threads. I replaced mine with a brass pressure relief valve. There is no need to remove the entire plug to drain, but it is easy to do with an open end box wrench. It may require taking the plastic plug to a plumbing supply store in order to match size and threads, but it's well worth it.
I use CPVC plugs from the local hardware store. At about 50 cents apiece, it's no problem to always have a couple of spares on hand.
Just keep in mind if your using the harder plastic or brass replacement plugs, its good to put some teflon tape or teflon pipe dope on the threads when you do your spring de-winterizing. Mike
Thank you all for your input. Why would Atwood design this water heater with a plug so difficult to get to!!!! Smart people with no common sense for sure!
I use a Tank Saver Anode kit made by NW Leisure Products LLC. It will fit Suburban or Atwood heaters. Fittings are brass and it has a drain valve built in. (similar to a drain on a car radiator) Works great. http://www.amazon.com/Northwest-Leisure-Pr..._sim_sbs_auto_5
RV is closed! The size tool for the plug was 15/16". Found a long handled wrench at a nearby hardware store that worked perfectly. Thank you all for your help. Between this site and YouTube it wasn't so bad after all. Sooner or later you just need to bite the bullet and learn to do these things to save some money.

I leave the socket right in the HWH by the plug. I always know were it is. Just have to find an extension and socket wrench. LOL.
I have a nylon plug in my heater too. I needed to remove it today, but my crescent wrench is home! I just happened to have a 4 way tire lug nut tool. The largest size 22 mm or 7/8" worked perfectly! Better than a wrench or socket.
