The waste water tank of motorhomes and caravans needs to be emptied regularly. Periodic emptying and cleaning is advised, especially when it is hot in the summer to avoid unpleasant odors. Besides that, it is not necessary to drive a full tank of waste water up the mountain.
The opening of the valve under the tank can be a tedious chore. Installing an electrically operated valve makes this job a lot simpler. The valve must be suitable for dirty water. Solenoid valves are not suitable because they only work with clean fluids. Electric Ball valves are an excellent solution. The ball valve is constructed of a ball with a bore that can rotate. If the bore is aligned with the ports the water can flow. Electric ball valves include a small electric motor in order to rotate the ball.
