Ditto, "learned the hard way" also. Now not only does our new unit have a functioning shut off, the experience of having it back up into the wallboard/sheet-rock, has kept me from every again forgetting to put the monthly cup or bleach or vinegar into the drain ! ! Yes, as gram paw used to say, " Learned the hard way", LOL !
