I've seen the retrofit drill and install a flush system, but not sure its for me. Although I do like the idea of being able to flush & fill the black tank directly from outside the coach.
As I plan my interior build out, my thought is to plumb in a T fitting into the vent stack, right by my water heater before it goes into the floor. If I adapt the vent to a flush/ fill water line, I can install another city inlet on the side of the trailer for flushing. (or I could just run a hose into the truck hatch and attach that way)
Since the vent is at the back of the tank, I thought this would be perfect place to flush water from.
I could access the connection inside the water heater compartment so it wouldnt be closed up permanently in the wall if it didnt work as intended, leaked, etc.
Any thoughts on this? Good or bad? Here's some old pics from when I tore everything out:
Although I'm thinking that it would flow fine with plenty of room in the pipe for air to breathe and/or burp since I'd be feeding max 50psi through 1/2" or 5/8" water line adapter into the much larger 1.5" vent pipe.
Am I thinking right? In other words, I'm not taking up all the space in the vent pipe.
Also, I would likely have drain valve open alot of the time too- yes?
Need a vacuum breaker after the hose fitting to prevent back flow into the water supply...a necessary evil.
