I am just about to put the camper back together but wanted to check for water line leaks and low and behold the dang pump wont work. It sounds good and when I took it apart nothing looks worn out or ...
What does a new pump cost? $100? Is the time and effort you have already put in worth it? If the pump is old, do you think something else might also be worn out? The death of a pump could end a trip or a major inconvenience.
When my old pump started to leak, I just got a new one, spent 10 minutes and put it in service. No leaks, no problems.
