Leaking drain valves

My 2005 Classic 25' waste drain valves are leaking a small amount.There would be about a quart after 4 days of camping.I ordered a bottle of Therford drain valve lubricant. If that doesn't work I was thinking of replacing the waste cap with a drian valve, going with the universal size.has anyone ever tried either of these fixes?

You can buy a "twist on" dump valve which attaches to the end of the sewer pipe. You twist it on like you would the end cap, then twist the end cap onto the drain valve.
Look at the Valterra web site.

Yeah, I tried one for a while. I really did not like it. Big, stuck out, was afraid it was going to break the connection. I was a lot happier after I went in and redid the valves. But...the add on will let you use the trailer until you can get it fixed properly. Not an easy or cheap job to do that though.

I'd put a jet nozzle on a hose and stuff the hose up there with the valves at various stages of open to try to clear any trash before I concluded the valve seals are truly bad. The proceed with the suggested solutions.

The job replacing the valves is not that hard and cheap enough if you do it yourself. I did mine with no difficulties. Total cost was under $200.

My owners manual says the Airstream way to replace the valves is to cut a access hole in the belly pan. That is what I did. It wasn't hard nor was making a cover plate difficult. With that said, AS should have put a access panel in the belly pan to begin
with.

Thanks, I am a newbie with Airstreams,I have owned a Rockwood Class A and a Greyhound bus.I didn't know there were different size drain valves, still not sure which ones fit the Airstream.I think I'd rather cut the pipe back and glue on a new drain valve.Would the pipe size be the same as other rv's? I still will try the Therford waist valve lubricant first.I think where its such a slow leak it may do the trick.

sometimes the blades get stuck on a piece of tissue or something, and you can clear them up if you flush water thru the tanks and exercise the valves while doing it. did that a couple of years ago and have had no issues since.
