low water point drain help
my class c was parked and hooked up to everything as usual. fresh water tank is empty. happened to notice a slow drip from the cold water low point drain hose. any idea where that hose connects? never...

The hose would connect to the low point drain in the cold side of the water system, but you already knew that. If you have a valve to drain the low point drains, it would connect to that valve and maybe the valve isn't shut all the way or is leaking. It is possible the same drain hose could connect to multiple drains if you have valves, such as maybe also serving as the outlet for the fresh water tank drain.
If you don't have low point drain valves, and just pipes or hoses with caps you have to take out and put back, it's almost certainly the cap not sealing well for some reason--either its loose or cracked or something like that. (That's assuming it's not water dripping down along the outside of the hose; if that's the case, possibly it's just condensation on the pipes, sometimes called sweating, that's happening to drip out there...or possibly a little leak somewhere else in the system.)
If the same hose serves as the fresh water tank drain hose, then maybe your water pump's check valve is leaking slightly, which often is due to a bit of debris or dirt stuck in it.
