questions.... I have them.. :D

1) the fresh water tank fill on my motorhome is the kind where you have to hook up a hose and have pressure on it, to fill, just like the "city water". I would prefer to have a gravity fill so water can be added from a jug, or from a hose, using this adapter that I already have. I also really dislike messing around with screwing the hose on.

Question 1: How big a deal would it be to change out that opening and is it something a person with a few skills could do herself?

I'm also planning to winterize by blowing out the lines, rather than pink stuff (except the traps, of course.) I may go back and forth a few times a year doing this, so it seems less hassle than removing all the stuff in the storage space, taking off a panel, using the pump, and then reversing the process before very long. I have a small compressor and hose.

Question 2: Is this the fitting I need?


Question 3: Are there any particular pitfalls to winterizing using compressed air? I've been googling around and reading here.

  • Do you have a gravity fill port?
    That is the correct one, I have a plastic one.
  • Many just carry a 12V water pump and pump out of a jug into the tank. I would not commit surgery on my piping unless forced to do so. My 12V was a spare water pump and sure enough my water pump croaked this summer.

    Whatever you do do not pressurize the plumbing system beyond it's design limits.
