There is a outside water drain installed on the front left corner of my 1969 Overlander. It is located underneath the water pump.
What is it for?
why does water drain out of it when I turn on my water pump?
I am trying to diagnose my water system (this is my first RV). I see water going through the water filter...
(I think the clear bulb thingy is a water filter).
...but water never makes it to the kitchen sink.
please note: water makes it to the kitchen sink when I have city water connected.
