The flush pedal on our toilet in the fifth wheel must be seated by pushing up with the foot after flushing. Otherwise the flush water does not cut off completely. We had the trailer hooked up to city water when our daughter stayed in it at our house around Christmas. A middle of the night visit by our son-in-law with an incomplete shut off and a continuing trickle resulted in a full black tank and a flood by morning. Fortunately, I had dumped the tank, so the flood was basically clean water. Carpet shampooing, drying and a clean out & drying of the basement was in order. Fun times for the weekend before Christmas at about 6:00 a.m.
