How many floors / levels does my black tank have?

[Henry Claeys]

Tom. Your idea sounds great provided the valve will close enough to hold 15 or
so gallons. I thought the valve was an all or nothing type thing meaning that
it either works, or it doesn't, but to my surprise it seems to hold some water.
Can you explain why/how it could behave that way and what to do to fix? Thanks
for your advice. Henry@... 1979 FC/SB 35, McAllen, Tx

Henry do yourself a favor and do this. Put a 1/2 cup of detergent in your
black water tank with about 15 gallons or so of water.. Add a couple of big
bags of ice cubes and take a 1/2 drive and then fill the tank and
dump. Clean tank
