Thank you for the video. People will be interested in it. Personally, I've never understood why you need to get the black tank that clean. My Bathroom sink empties into the high side of my black tank. All I do is pull up to the dump station, open the valve, and if there is no one in line behind me, I pour about 5 gallons of water down the bathroom sink. I've been doing this for years and have no problems of any kind. That is my way of doing things and I understand other people have a different way.
I don't understand how you have 120 psi in water pressure. Nothing around me is more then 60 psi. Might be where you live but, here in the rural Midwest if you get water pressure any where near that high there will be a disaster because our plumbing is not used to that much pressure.
Have a nice Day. Make more videos. I enjoyed this one.
