WOW nadkaw1957, you have been busy! I would love to see some pictures of your transfer switch for the inverter..
I installed a 2 gallon accumulator tank and took a few pics in the process...
I got it done on 02/14, thanks to the agreeable weather! Please forgive the crappy cell phone pics... I forgot the camera..
I had originally planned on mounting it to the floor, but that would have blocked access to the back of the converter and breaker box. Under the shower, was some 3/4' OSB and the perfect spot for mounting the tank. I used two pieces of pipe strap and some of the square head screws from a wrecked Sunline 299SR, that I parted out.. When I drew the screws down (Or is it up?) the straps got very tight. They hold the tank very securely!
I mounted the tank, so that I would have easy access to the air valve stem.
I then triple checked, to make sure I cut the city water inlet pipe and not the black tank flush pipe... I pulled the braided line into position where I thought it would be best and cut the line for the tee.
I still have a bunch of the blue PEX from the 299 and used some on this mod. I crimped the tee on one end of the piece and the new valve on the other.
I then crimped the new piece into the existing line.
I hooked the braided line to the valve and it's done! (Except for cleaning up the antifreeze.)
I left the valve turned off, until I get the chance to check for leaks in the PEX and in my water heater mod.
