I need to replace my black water valve on my 2007 5th wheel Keystone Montana because it is leaking a little. I thought while I was doing it I might as well do the grey water valve too. Does anyone know what size they are? I would assume the black water is a 3" and the grey I'm not sure. Would like to hear from a Montana owner that has replaced these valves. I watched a video but of course all brands of RVs can be different.
Thanks
Oh, also I am hearing things like make sure it's not a cable valve and are bristol and valterra valves interchangeable? Now I'm getting confused.
