Few weeks later, I opened it all up again, and bunches of water poured out. Then I drove around for a couple hours, watching water trickle out behind me the entire time. Pulled into my driveway, and still a slow steady stream of water trickling out. It comes out this same faucet fast, when the system is full...
I cannot imagine where it is coming from!! Has to be gallons of water that is very slowly draining from somewhere. I had the camper apart a few weeks ago when I drained the system and could see the water tank was empty. So, I guess from the hot water heater.
Long story to a short question.. Is that normal? Does it take a while for the water to drain?
Thought about this...the hot water heater ['16 Hawk] always holds about 1 gallon even when "drained" into main tank and the main water tank in turn holds perhaps a gallon or less after normal "draining" of the entire system [line exiting the main tank is not at lowest point]....what could be happening is that the residual water in these two tanks does not drain even when drained on a slope but may put water into the main drain line as the vehicle is subsequently driven and the water in tanks sloshes out into the main drain line [line that exits the rear of the camper] as the truck leans and bumps up and down...a way to check if the hot water tank is contributing this water is to turn off the the hot water drain to the main tank, after doing the usual complete draining of system, close rear drain spigot, drive around over different road grades and surfaces, park with spigot downhill, then open spigot at rear of camper to see if water flows out....if yes, then the main tank is contributing this "new" water....repeat to see if more water is still in main tank....if no, then open drain from hot water heater to main tank [closing rear drain spigot] and repeat driving around and checking again at spigot for "new" water...if yes, then hot water tank is contributing this new water via the main tank and then main drain.Kathystrns@gmail.com said:I had the same thing happen - thought I had everything drained and a couple months later was messing with things and a lot of water came out! I'm very curious about the vodka/grain alcohol option, but unsure how to implement it and if it really works. Don't really want to put antifreeze in the system, but would like to be a bit more confident that winter won't bring problems.
OK...a lot of messing around to find out where the "extra" water is coming from, BUT this does not resolve the questions of does this extra water threaten the water system lines if it freezes and, then of course, how do you eliminate this extra water if it is causing damage.
Whew...sorry, got wound up there!
