Topic: Texman 182g Mods Posted: 11 Feb 2019 at 8:35am |
Worked on two mods Sunday. The recirculating hot water first. I installed the valves and did a quick pressure check and that all seemed good. I opened the manual valve to do further pressure checks but i ran the pump dry, so i will have to prime it i suppose to test further. I was out of time to add water and do the real tests and is still need to install the rear mixing valve. The main reverse polarity valve is wired to the red/yellow switch in the panel and tested and works fine so far. It is really tight where i added the new valves. Difficult to get clean square cuts in the Pex. i think i got it in correctly since i saw no leaks with initial pressure check.

Testing the thermostat with a 9v battery. it works so far. i could not get the relay to work yet using 9volt. I think it must need 12 v to function. I plan to test all of this before cutting pipe in the pod to install all of this.

this is the mixing valve that will go at the rear of the pod (farthest point from water heater and pump)

In the 179 I can see the fittings to them from the inside, there are two sets. I haven't tried to remove them yet.

I meant, either cap them off above the floor and/or remove the tee drops inside the trailer and then spray some closed cell foam into their holes from underneath so they don't become dead end water filled lines with no circulation that could freeze up. Basically, make them go away. If your trailer is plumbed like mine, that should leave only the pump suction line and (maybe) the fresh water tank to insulate.
Don't forget to add valves to the outside shower lines (inside the trailer). I plan to just drain those lines back, then shut the valves, I never use the outside shower in the winter anyway.

what do you mean by "remove low point drains" ? just cap them off? cut off and join together for recirculation?

There aren't any exposed water lines under my pod except the low point drains and the pump suction line. Nice clean plumbing design. Sorry if I'm repeating, but I plan to just remove my low point drains, I don't believe they're really needed, it would just take a little more antifreeze to winterize without them, if that.
Sticking stuff to polyethylene can be problematic, I suggest trying a small area first. Some folks swear by flame treatment to activate the polyethylene surface for adhesives, not sure if it would work for polyurethane.

offgrid i plan to add the second Tstat to the water heater as you did to get a lower heat set point. I still need to get under the pod and trace all the water lines and add pipe insulation as necessary to the exposed lines. I think you mentioned insulating the tank as well with closed cell insulation. I am still in planning as far as the tank insulation. i will test with uninsulated first and see how it goes.

thanks and the tests are about to begin. supposed to be freezing temps this weekend for me at night so should be good to test.

That's a very interesting set up texman. It looks like it will work very nicely.
