Tim & Laura,
I purchased a coach that had been used very little for 5 years and a slow drain was a problem. Newell advised me to put in a quart of the standard black tank chemical available at Wal*Mart. They had me fill the water to 3/4 & drive with the solution & leave it in for 2 weeks. After 2 weeks I drained the solution and it drained normally & my indicator lights worked properly. My tank wasn't clogged totally, but it is an inexpensive fix to try. Since yours is clogged I would be inclined to double the chemical. A quart cost $8-$9.
