Well, I didn't add water to it yet.
I put fishing pole holders in the bathroom. The bathroom/shower are pretty much emergency use only, and it was the only spot they would fit.
I had made several 120vac - 12vdc converters to run the led
light for the water heater, but they kept breaking, must be from the road vibration.
I talked to an electronics shop, and found out you only need a diode of the right resistance, and you can run an led off 120vac. I rewired the whole setup, and it works great. It should last for a long time, too.
