Keystone Sprinter 5th wheel - camped over the weekend and toilet got stopped up. Have tried everything we could think of -- cannot get it to drain. Help! Obviously need to resolve this quickly!
By some chance, Are you leaving the black tank drain valve open to the sewer when you are campimg? If you are, you will drain all of the fluid out of the tank and leave the solids to build up. If you are, the above suggestions will work to clear it and you need to leave the drain valve closed until you empty your tank in the future. Good luck and let us know hpw it works out.
