Jayco White Hawk Water Heater

[medicman4877]

I am trying to find a replacement plug for my water heater and do not have access to it right now. Does anyone know if these traditionally come with a Camco or an Atwood water Heater? Will it say on the outdoor panel anywhere or will it be labeled on the actual water heater itself? Any suggestions on which replacement plug to use? Some people have said to just replace with the plastic plug and others have said to replace with the plug that has the anode rod on it for corrosion purposes.

My 2014 DSBH has an Atwood water heater as indicated on the bottom right corner on the cover. I'm not sure what size the plug is off hand. I do know it is a nylon plug.
Wish I could be of more assistance.

Atwood water heaters in the White Hawks don't require anode rod. Just replace the plastic plug. My guess on size is 9/16 inch.

IIRC, it's 1/2" NPT. I picked up some PVC ones from the home store for a buck each, in the plumbing department.

I was thinking about the anode rod because I have what looks like calcium build up around the existing plug. Plus it has a small trickle of a leak when plugged into city water connection. It gets worse when the electric heater is turned on. Just wanted to replace with a new one and try to seat it a little better.

Both our TT's have had Atwood WH. I believe there is a label stating the manufacturer on the WH someplace and I seem to remember the Atwood "A" being cast into a metal part on the WH. They're aluminum and do not require an anode rod. I've bought replacement plugs at a big box store and at my local RV parts place. They are usually come two to a card.
An anode won't address calcium deposits, they're to prevent galvanic corrosion. I think North is correct about them being 1/2" and they are pipe threaded.
You mention a leak, if it's around the plug I'd try replacing it. Some folks wrap the plug with Teflon tape or slobber some pipe dope on it prior to installing. I don't use anything, but that's just me. I tend to replace the plug when it starts looking "gnawed upon" which is sorta once a season or so.
