Winterizing/antifreeze questions for a newbie

I attempted to winterize my trailer today and a couple of curiosities developed in the process. Hope someone can fill me in ..

1. My goal was to use only my trailer battery to power the water pump while winterizing, but neither the pump, nor any of the electrical features in the TT worked until I plugged the trailering harness into my truck. What did I do wrong?

2. While filling the pipelines with antifreeze, the lines leading to the hot water tap and the hot water heater were not sucking any antifreeze.

A. I assume one of the valves by the water heater needs to be turned in the opposite direction? Right now, the three valves near the water heater are all turned in the opposite direction from the line. Is it the valve that connects the two hot water heater lines (input and output) that needs to be turned so it's in line with the pipe, or???
B. Since I've never used the hot water heater in the TT, is it even necessary to fill those lines with antifreeze? I'd rather not if I don't have to.

Thanks for your feedback!
Ray

Drain the wh, then operate the valves so that the wh is bypassed. Then continue on with the winterizing.

1. You should be able to run the pump with just the battery, no need to hook up to the truck. Is your battery dead?

2. The pump should pump water to the hot water lines as well as cold.

3.

I am betting that the battery is dead and the hot water tank is filling with antifreeze. You need to bypass the tank.

JThanks for the feedback folks.

Just to clairfy: All of the hot water tank valves were turned perpendicular to the pipelines, which I assume means they were in the Closed position. Consequently, I would think that NO antifreeze would have entered the water heater. (I saw NO pink in any of the lines around the heater)

As far as the battery issue, it was fully charged when I hooked it up to the trailer, so I'm still baffed as to why I didn't have power.

This raises another question: Is it possible to power a trailer by simply connecting its power chord to the truck's socket and not even hooking up the trailer's battery? Just curious.

Thanks again.

OK here is a better diagram. The middle valve should be open and the two that go to the water heater should be closed for bypassing the water heater. If the middle valve is also closed, then antifreeze cannot go through the hot water plumbing so it could freeze. Check your fuse by the battery to see if it is good and you have a clean connection there and at the terminals.

Great, thanks, Crab.

By the way, I need to complete adding antifreeze tomorrow. To run the water pump, can I just hook the trailer's power chord up to my truck, or does the TT's battery need to be attached?

Need your battery to complete the circut if using your truck. If you have 120V for shore power then your converter may work without the battery.

Actually, it should work without the battery. Just watch your tt battery cables that they don't touch anything metal.

On the battery - have you checked your fuses? There is one at the battery and two in the load center. Possible one of those is blown - more than likely the one at the battery given your description. Also check for coorosion in and around the terminals and fuse holder - it can cause the same thing to occur.

Is the fuse "at the battery" attached to the wiring harness? I can check it. Do you know if automotive stores or hardware stores stock these? Also, by "load center" do you mean the circurit braker box inside the trailer?

Thanks.
