black/grey tank leak

Just wondering, just finished my first year of camping in my Windjammer and I really enjoyed it and it was pretty well trouble free. Hope to travel much more in the up coming year. Question is after set up, I pull the cap to hook up the sewer hose and I always have a couple of cups of liquid come out before I hook up the sewer. I have checked and both the black and grey valves are closed. Is this normal ? Is there any adjustment ? or does some liquid just sneak by due to the movement of the tt while on the road. Its at the dealer getting some work done, and I have asked them to check it, not sure if they can because the unit has been winterized. Its not a big deal but I don't think it should be doing that. Thanks in advance.

Do you know this by looking at the physical valves or by seeing that the dump handles are totally pushed in? I only asked because, although my handles appeared to be closed, both my gray tanks valves were not closed tightly. My dealership service department had to drop the belly cover, reroute and even shorten both dump cables and make adjustments to the valves. It appears the galley valve closes completely but that the bathroom gray still leaks.

Yes I have. I've tried to figure it out but not yet. Seams there's a secret pocket of poo holder that decides when it want to drive me crazy. Sometimes nothing, when theirs family or neibors watching I better have a bucket. Most the time after flushing for 10-20 minutes its ok, but not 100%. More often than not when using the blue honey wagon (regardless of how lone you leave it connected) its rears it's ugly head next time you take that cap off. Not just a lump but close to 1/4 - 1/2 gallon. But not gonna let "a little bitty tear let/get me down".

I found my main drain which all the tanks drain into had a bit of an "uphill" angle to it and allowed a small amount of "stuff" to collect in the line while traveling. Upon opening the waste cap "stuff" would flow out (a couple of cups or so). I grown accustomed to carrying a 5 gal. bucket with me and I placed that under the cap prior to opening it. The "stuff" is poured down the sewer prior to hooking the sewer line up to the ground receptacle.

Thanks for the responses, I went to the dealer today, they had finished my service however they were unable to check out the tank drain because I had winterized the unit. They gave me some hints on what to look for and if the problem persists, when I de-winterize they will look at it then. It could be operator error, but I will check it closer next time. By the way how long do you flush the black tank, I am only flushing for about 5 minutes. I have a feeling that is not long enough. I do not have a clear elbow to observe what is being rinsed out. Its only late November , but I am already ready to go somewhere. Cabin fever sucks. Hope everyone has a great thanksgiving.

Chuck- I have noticed the same occurrence on occasion. I have a similar unit to yours... non-jammer though.

I sprayed the seals with a little silicone spray and used a plastic straw to chase out the groove that the blade of the black and grey valve sets in... seemed to help. Might you have a little debris in the groove that doesn't allow the blade to seal fully?

I usually rinse for about a minute and a half or so with the black valve closed and then dump...let it run for another 45 seconds when empty... and repeat about 3 or 4 times...

BTW... Dewinterize and head up to American Heritage- place is hopping this weekend. We drove down from northern NJ just ahead of the snow on Tuesday night and are doing Williamsburg for Thanksgiving!

I always cycle the valves 3-4 times after I dump my tanks to make sure they seal.

Thanks again for all the ideas, I would rather figure it out, instead of taking to the dealer. I will include them into my flush out/ dump procedure.

After 10 years of camping in three different rigs, I have, from time to time, experienced this same kind of problem. Without addressing the root cause, you may want to adopt a plan of "containment". I have an auxiliary blade valve that "bayonets" on to the end of the drain pipe. This way if you do have a minor seepage (or even a major valve failure), none of it leaks out onto the ground. Nothing flows until you pull that final valve. You probably still should try to figure out what's wrong with your rig, but an auxiliary valve gives complete peace of mind.
