Flush kit for black tank

Flush King will run water in through the outlet and fill tank. Not much different than pouring in water. A tank flusher mounts in the side of the tank and the water pressure going directly inside the tank will help clean it out. Just drop the under belly and install it, then seal it back up. You'll probably be pretty disappointed when you see how little insulation your "Polar Package" has in the floor. Most of the Polar Package is mainly a decal on the side and a bunch of hype.

There will probably be two different "camps" out there on this issue. I have a year old fiver with OEM black tank flush system and never use it. I will only use my attached FLUSH KING.

The Flush King allows you to back fill your black tank from the bottom with a lot of water. Simply keep your gray tanks closed and use the Flush King to rinse out your black tank as many times as you want. If you decided your gray tanks need a cleaning, then close your black, open each gray tank one at a time and use the Flush King to rinse those out. Finally, the Flush King give you an extra gate valve at the end of your sewer boom so you are sure to never have a
surprise when setting up camp and taking the cap off of the end of the sewer boom.

There is a video out there where someone in a shop had a RV black tank sitting on a table. The video shows it hooked up to a standard OEM black tank flush system, and then hooked up to a Flush King. It was interesting to watch the OEM flush system work. Most people think it sprays all over and cleans the sides of their black tanks, but they would be WRONG. It does spray a little but generally it is only letting you put water in your black tank from high on one side. Whereas the Flush King allow you to fill from the bottom.

At the conclusion of this video the RV guy says that one system is about as good as the other.
