THE WILD DOG
If you stop the video on the right hand side of this page
at 29 sec you can see the basic pipes including gas line. They are using a double line out but it’s normally just a one line in and one line out standard hook up. I used stainless steel hose water lines in and out and black iron on my gas line. The water lines threads are standard water hose type. It’s a walk in the park.
This is not my system and even though I’m not a plumber I could do a better job than this guy did. LOL
I think the way to plumb anything is to make it as simple as possible. And figure sooner or later your going to have to replace some part so make it easy to get to all of it.
The chances that you are going to have to work on it increase because your pulling a trailer or driving a truck and most plumbers work on stationary homes or offices, and they don’t have the vibration that your system is going through.
SO SO SO Use stainless steel hose and run from your preasure tank to the inlet side of your tankless water heater and from the pressure tank to the cold water side of your faucets.
Run stainless steel hose from the outlet on your tankless unit to all your hot water faucets, and make this run AS SHORT AS POSSIBLE, so you don’t lose a bunch of heat in the process.
Run your gas in and exhaust out.
