I finished installing the outdoor shower today. It’s awesome! I wired in the lights, a couple 12 volt LED license plate lights with a waterproof button. I had to make another copper button mount from a blank I have laying around, punched, then filed larger as the biggest punch isn’t enough to fit. Screwed to the wall, perfect. I found some 14 gauge wire to attach it all with wire nuts all pointed up to avoid water damage. I’ll E tape it next. I had to get new fittings for the L5 on demand heater, installed, not cheap as I needed to double up the gas in line to get it to fit the 5/16th fitting. It’s all installed with 3/8″ water lines and the 5/16 gas inlet. I used the yellow Teflon sealing tape required for gas. I found an empty Blue Rhino tank in the garage. Meanwhile, I borrowed a tank from the vardo to test the system. It works perfect. I took a shower after adjusting the heat, 4 gallons of water for a continuous shower. You have to be careful when it runs out as the heater ejects a steam after a few seconds. But it’s fantastic, a hot shower without PG&E, totally battery power solar charged. Off the grid. Perfect.
