We're tired of paying $120/hour to have repairs done on our 1996 Coleman Niagra. We just can't afford it. So we have new summer plans, along with camping in our PUP, we're going to start doing our own repairs. The water pump is making clicking noises and not pumping water. We paid the RV repair shop $60 to tell us this. Any suggestions on the kind of pump needed to replace the old? Or sugguestions on how to test it? We just picked it up and will not be able to start work until tonight. Thanks!
