Currently trying to get my 98 Coleman Westlake back in shape. I only camp a few times a year, so for the past several years, I've just been making do with everything that's broken. One of the things that I need to fix is my water tank. I attached a hose from the faucet at our campsite directly to the camper without any type of pressure regulator and now can only seem to fill it partially. And with that, at a certain point, the water looked yellow, so I also tried to sanitize it with a half cup of bleach and have never been able to get a "fishy" smell out. I feel like I should just start over with a new water tank, but is that something I could do myself? Would I also need to replace the hot water tank? All the lines? I don't know where to start, but once I know what to do, I'm actually quite handy with repairs. Any suggestions would be much appreciated!
