Our regular motorhome was booked about 4-6 weeks in advance so I ordered the exact part that broke and fixed it myself. It took me most of the day, but I learned over time that I really did need to go to the local hardware store to get some flexible caulking compound, some pipe and some cement, a saw, and various spammers. Our drain valve no longer leaks and I have new plumbing skills. This is a special part and it was a direct exchange.
