I have a new camper and It has a black flushing connection, never has a camper with this feature and now I was wondering what is the purpose of the black flush
Please use a separate water hose for back flushing, not your regular hose used for city water. I usually have a green garden hose for the back flush, or if I do use an old white regular water hose, I put black electric tape on both ends so I know to only use it for back flushing.
the flushing device is one of the best things ever made for cleaning out your black tank. You use less water than any thing else ever made for cleaning your tank. I installed one before the factory ever started in do so. you use less water and spend less time cleaning so you can get in and out of the dump station faster.
The tanks are near flat on the bottom. The flusher gets more of the "lumps" out. Use a clear elbow on the sewer connection and run the flusher till you see no more brown trout swimming downstream. Even then, there usually more remaining.
