I have a teardrop trailer we’re taking to Moab. It has a 20lb propane tank so I can light the stove. I wanted to add hot water to my small kitchen in the back by buying one of those propane water heaters for camping. I thought I would just get a splitter for the propane tank and run a hose to the propane water heater and this would basically work. When I set it up like that neither the stove light or the propane water heater. When I set them up separately, with each line going directly to the 20 pound propane tank they will work. So, what is my issue? I’m going crazy here. I even turn on the gas really slow when I have both of them hooked up to the splitter just in case there’s a shut off valve internally. If I remove one hose from the splitter, it won’t work on the hose that is hooked up. Seems like something is up with the splitter. It does register that I have pressure in the propane tank. So I have No idea. Each hose has its own regulator.
