Questions about replacing city water inlet on Sierra fifth wheel
I have a 2001 Sierra 33' fifth wheel. Model number is 30RLSS. I have to replace the city water inlet because the check valve is definitely bad.
Firstly, which one do I buy? Please be precise if possible. By that I mean what make and model. The one on trailer now is flush mounted with 3 screws. Screw holes are 1 3/4" to 2" apart. (Sorry, but I can't say exactly because trailer is located in a campground in another city and I didn't have a ruler with me. I cut a piece of paper the length of center to center screw hole spacing and measured paper when I got home.)
I spoke with the campground maintenance man and he said besides a new city water inlet I'd need 2 things. One was butyl tape and I think the other was plumbers putty. Does the butyl tape go between the city water inlet flange and the outside of trailer? If I'm remembering right about plumbers putty, where is that used?
Maintenance man said he'd do job for about $100. I'm pretty handy so I'd like to do it myself.
