Lamonte, If your waste valves are manually operated, I think these are a standard size so any replacement (Valterra, etc) should fit. One suggestion I have is to empty your tanks fully beforehand. What I did was to tilt the MH using the airbags to completely empty the tanks. Less mess the better! Also, lube the valve gaskets (rubber ring) and handle shaft with silicone grease (plumbers grease) before installation. A little goes a logn way. Just get the mounting bolts sung, not too tight, so the valves are easy to open and close. Maybe use a drop of blue Locktite on the bolt threads, if they don't come with locking nuts. One job I have had too much experience with!
