How did it get into the drain pipe when the last time i emptied there was nothing there. Do you think my valve to the black tank is not shutting all the way. After I drain i hook up the water hose and put some water back into the system, and then my wife goes into trailer and flushes the commode a few times and then drops in some pills. Am I doing this wrong and if so what do you suggest?

Nope, you have it exactly right. The blade valves just wear out after sitting dry for a while. only way to fix them is to replace them. Don't bother with lube or all the other junk that folks talk about on these forums. I work mine in and out after I dump, just to keep them freed up internally. When they leak just replace them, they are cheap. 4 nut and bolts and the old one is out. They are very simple to change out. Takes about 10 minutes. I'd pick up some PB blaster to put on the nut and bolt set to loosen the rust to make the job easier.

Empty all your tanks. Then add some water to only 1 tank at a time, emptying between tanks. With clean water in one at a time, you'll find it.

My black tank valve leaks by just a itty bitty bit. Stinks, but I just haven't gotten around to getting new seals for it.

Read several of the previous posts! There are several that describe how to check for seeping!

If ANY black sewage comes out of the drain pipe when you remove the drain pipe cap while the black tank drain handle is in the off position.
Either:
1.) The black tank dump valve was NOT fully closed when you lasted dumped.
OR
2.) Your black tank dump valve IS seeping.
