    Baby steps..

    Afsupply.com sent me the union sweat version of the Honeywell mixing valve by mistake. So I had to re-order the NPT version somewhere else. I need to have it in hand in order to mount the water spigot and valve, because there won't be a way to panel mount the valve, so I'm hoping I can use some solid brass pipe and elbows to connect the outlet to the water spigot, therefore "suspending" the valve just right on the panel.

    Here's where I'm thinking to put the heat exchanger - on the frame rail using aluminum plate and square u-bolts. I'm concerned that it's too low? 2ft drop to the exchanger + 2 feet back up to the heater core.
    I have no idea if that's a problem, it just sounds like adding a lot more work on the water pump.

    Project is done. Everything works perfect. Water temp is a solid 110+ degrees. Shower head is a low flow model, with 3 settings: 0.5/1/1.5 gpm.

    Garden hose quick connects are great.

    Looks good, one thing I would change is the brass fitting. The spring inside will rust!! Change over to SS and you will be fine. I know form which I speak. I could not for the life of me figure out where the rusty colored water was coming from. I took apart the brass fitting and it was loaded and corroded, the spring was the problem.

    Thanks for the tip... mcmaster doesn't even sell a stainless version of the universal quick connect coupler. I think I'll have to learn this lesson from experience. Can't stomach a 12th order for fittings at this time

    Ebay Carpet cleaning HP quick disconnects. Good luck on your system. I love hot showers in the boonies.

    the only quirk I'm dealing with so far is the garden hose quick connect socket for the water input side. It's a single flow valve, aka closed, but I discovered that it requires substantial water pressure to actually stay closed. So when I pack up the hoses, the fitting starts to leak some water. I'm thinking my options are

    1) put a ball valve behind the panel. Pros: will definitely work. Cons: another thing to do
    2) check valve. They require 1-2 psi to prevent backflow. Do you think this would work?
    3. Epoxy a QD plug fitting shut and keep it inserted.
