The dreaded "tank problem"s.... I am having trouble with both my gray tank and my black tank. 1) My gray tank is continuously clogged. I have to take a plunger to it about once a month to empty...
The Flush King attaches to your sewer exit.....easy to use + highly recommended. all you need is an old hose to shoot water up thru FK into grey/black tank. this should flush your tanks. Has a clear fitting so u can see what is draining out. wouldnt be without one! Once clear use proper chemicals!
