Just make sure when you install the new valve, that the rubber seals on either side on not pinched, bent, or stuck on the bayonet valve. Learned this lesson the hard way. It caused my black and gray valves to never seal, and always have back up at the drain cap. Use vaseline, or some type of heavy grease to hold the seals in place on either side of the valve, then install the new valve, insuring the seals stay in place. Should take car of the nasty non-sealing problem, like I ran into to. Otherwise they are easy to change, might be harder to get to them depending on your trailers under body insulation.
