Future modifications on low point drains. Opinions? Advice?

Hello all,

I am planning on some serious winter camping around January 2015 (Maine, Vermont etc) and I am considering some upgrades for winter camping.

One of these mods is to all 3 low point drains. The hot and cold line drains are valve controlled from inside and dump outside via aprox 6" of PEX(?) water line running straight down. The fresh water tank drain is just some clear 3/8 id tubing that runs to a valve on the side of the motorhome.

I am thinking sharkbite fittings(90 or 45 degree elbows) for the hot/cold lines, extend those lines to the outside of the mh to new valves (next to freshwater tank drain). I can then insulate the lines and fittings with foam and duct tape. I am also thinking replacing the entire freshwater drain line from the tank to the exterior valve and insulating as well.

Finally, I want to wrap the freshwater tank in reflectix (top and bottom as well. The freshwater tank is inside under the bed and I can put a light nearby to heat it.

Does this sound like a battle plan? Has anyone on the boards done something similar? I'd appreciate any input.

Thanks,
DS

  • @westend, I gotcha with the heat thing. I do plan on installing ultra heat pads on the black and grey tanks as well as the big drain pipe.

    @Old Biscuit, you make sense too. I'm re-thinking on the freshwater drain. Maybe just a valve inside and drain straight down?
  • Valves are inside MH were they stay warm.......
    The lines after valves just stick straight down. Which is not a problem cause with valves closed there is no water in those lines.


    I think you are trying to solve a problem that doesn't exist.
  • I see you're from SC, that would explain the questions. The thing is, you can put 12" of insulation around a tank or pipe and if ambient temperature stays below freezing, the water inside the pipe or tank will freeze. You need to apply some heat to the pipes and tank to keep them from freezing. If using conventional pipe heat-tape, you can insulate around that for better heat storage.
