help with holding tank please
I'm trying to fill my holding tank and test my water system. Here is the problem... I have no clue which valves under my sink should be open and which should be closed. There are three valves under the sink. Problem is, when i turn the water pump on, water starts running out of the pipe located under the holding tank? Should all vaves be open? All valves be closed? Or a combination of open and closed? I feel very stupid and humbled, but I've tried every combination, and I'm not getting pressure. This is for a '71 Overlander.
