Hi I'm Rose and my 2003 coach man class c has outside water system for filling water tank or city water use. One valve handle broke, it's clear plastic looks like House toilet valve shut off but size/number of teeth are different. Lowe's didn't have it or a plumbing supply either. I emailed coachman but haven't heard back. Took a picture of the good one I still have left when I need another one any ideas please?
