Tom,
While MDPE is not difficult to weld, it can not be done with air. You have to have a welder that uses at least nitrogen or some other gas.
If you want to get technical and buy the tank, regulator, etc to use Nitrogen that is a recommended practice, but we are talking about a RV water tank and not a critical application such as something to be used in a factory or chemical plant. When you use air it slightly changes the MDPE's chemical or molecular composition, or so they say, but I've welded at least 8 cracked RV tanks over the past 10 years for people using air, as well as so many kayaks I've lost count, and never had a call back. I guess a bonus would be if you did buy the Nitrogen setup you could then use it in your RV tires.:D
