Hi Scott,B Yes, that is entirely different. My heater has a 3/4" NPT steel
fitting in the tank. B I cannot offer any advice here other than call/email
the manufacturer to see what thread they say it is. B Maybe you can get online
and download a manual? B Is there a installation/spec sheet that came with the
tank with phone numbers or other information?
best,

The fitting into the tank itself has a hex on it, but it's made of plastic too
and I'm honestly not sure I have the stones to attack it with a wrench. Should
I?

Hi Scott,
I did something similar, entirely removed the valve and plumbed-in a 3/4" pipe
into the tank and just used a standard full ball valve.B I am attaching the
picture here, but it probably will not post to the list.
I think tanks generally use standard NPT pipe threads.B Maybe a
taper?B best,

Guys,
Got new water heater for house. Want to replace existing drain arrangement
with ball valve for better draining.
The fitting into the tank I think is probably not replaceable. But I could
replace the plastic plug and screw a fitting/ball valve into it. It looks
like this:

But I'm not sure what that thread is. It's not NPT--it seems to be about
twice as coarse as NPT.
I tried a 1/2" NPT spigot iftting I has here and it screws in, but it looks
like it might be cutting its own threads into the fitting on the tank,
which I think is Bad.
Anyone familiar with what that thread might be?
The plug's plastic so it won't rust, but it looks like it's just asking to
have those tiny holes clogs, or for the whole plastic plug to embrittle and
break. A nice ball valve with a big handle on it would be preferable.
Scott
