Sorry for the lack of updates but I have been in/out of town on business as usual. I am still searching for a reasonable commissary. I found several reasonable small warehouses that the health department would allow me to convert into a commercial kitchen but they are in the next county over and 25min away.
Ever since I had to remove my old electric water heater per the county requirements, I installed a LP tankless. I ran CSST from my existing gas lines to the new water heater on the other side of the truck. This past weekend I removed the CSST as I read that it is not safe for RVs, etc. due to vibration and I do not want to explode.
I have been trying to find a plumber to come out and put in black pipe but noone is willing and I cannot find the original installer.
I am going to attempt this myself. What pipe thread sealant have you guys used? How have you tested your lines for leaks?
