Subject: Black tank flushing?
Posted: 05 Oct 2016 at 5:19pm
My vacuum breaker/check valve was leaking on my 177. It turned out to be a loose fitting so I just tightened it by hand and the leak stopped. I just pulled the wall back enough to get to the valve. The corner molding and 1/8" paneling are held in place with staples. It is very easy to remove the paneling. The other thing I found was the sprayer mounted in the back water tank was clogged up and so there was a lot of back pressure which contributed to the leak. The back water flush valve is held in place with 3 screws. I took it out and unscrewed the fitting from the hose and that's when I saw all the buildup inside it. Took a small brush to clean out the gunk. The small holes that water squirts out of had burrs and had never been cleaned up. I used a sharp exacto knife and a welding torch tip cleaner to remove the burrs. Everything is working as it should
