Hot Water From Cold
We got out camping for the first time this year this past weekend. As such, I ran water through the camper to push out the antifreeze I put in last fall. Then, I switched the valves to fill the hot ...

That makes sense.
I guess that the next time we camp I will see if it's in the lines or in the faucet. If it's in the lines, doesn't seem like much can be done. If it's in the faucet, I can replace that. Any other comments/suggestions?
As suggested somewhere above, it can't hurt to try adding a check valve on the cold inlet near the HWH. A shark-bite type would make it quick and easy. Maybe around $15 or so. I'd just put it in and keep your fingers crossed. Should be fine downstream a little from the shutoff valve where there is room to cut the pipe. The plastic fitting at the hot outlet at the tank would appear to be a check valve.
I wonder if the existing check valve isn't working if that would have any effect on the situation?
Not sure what the black "thingy" is between the swivel fittings and tank. The existing check valve would be at the top of the tank at the hot outlet.
Still curious why someone went to all the trouble to redo the hot and cold piping and fittings like that? If I were going to that extent and using brass PEX fittings, I think I would have used a decent quality brass check valve. But there are plastic PEX fittings under the sink.
This is a Sharkbite PEX to PEX check valve. One or more competitors make a plastic one. There may be one with a threaded male or female thread on one end, which maybe is what is there now. Definitely many available with threaded female on each end (non-Sharkbite).
