WAGM - Thanks for the information. Well, I tried to get a couple of the electric drain valves from CW - hoping they were still on sale. They told me that they no longer offer them in the catalog. Connected me to parts and the gentlemen there told me he can still get them, but they have gone up in price to $109+ each cause they now have a red light on the switch to let you know the valve is open. Measured my existing valves and found one to be 2" from the gray water tank and 3" from the black water tank. The 2" would require some adapter kit. Really did not need the light to tell me I had just opened the valve - did not plan on leaving it open for an extended time. It would have saved me from going outdoors to activate the valve when connected with full hookups. Unless I hear of a better deal, I don't feel like paying close to $250 for something that I'll not use that much.
