I am trying to set up my own dishwasher / shower water pump system for my base camp so that I can wash dishes and take a hot shower if needed. The pump would need to be powered by a 12 volt marine battery. Would like to be able to turn the water on and off like in a sink at home. Additionally, would like to have hot water for it and a shower that would be placed near the sink area of the tent. I am sure that others have done this, but plumbing and electrical motors are not my specialty.
