someone with that model will surely chime in shortly
but there are likely more than one set.
If you are able, you can easily find them crawling around underneath the coach....just a pair of open ended plastic pipe/tubing pointing through the underside of the floor straight to the ground. Mine is blue pex tubing for cold and red for hot. Go inside just above that location to find the valves. Mine has little white plastic T handles that you pull up on to open (not turn to open)
