RE: batch feed or switch under garbage disposal. (Follow-Up #15)

Before deciding on a batch feed disposer, you need to check one critical bit of plumbing configuration. Batch feed disposers are taller and therefore hang down lower under the sink than a typical switched (air-switch or wall-switch) disposer. Because of this, the drain outlet on the disposer is also lower. It is critical that the outlet on the disposer be higher than the drain line opening on the wall at the back of your cabinet. If it isn't, the disposer will not drain properly, and you will always have water sitting in the bottom of the grind chamber of your disposer. This will significantly shorten the life of any disposer and could result in rotting food debris remaining in the bottom of the disposer. CHECK YOUR DIMENSIONS CAREFULLY. Be sure that the drain outlet on the disposer will be above the height of the drain outlet on the back wall of your cabinet.

I really like batch feed disposers, but if a batch feed disposer doesn't work because of your plumbing configuration, then you definitely want a disposer with a wall switch or an air switch. Having to deal with a switch under the sink is a minor nuisance, but over time, a major annoyance. You don't want to go there. Personally, I prefer a wall switch, but there are many people on this forum who swear by the air switch arrangement. Just keep in mind that an air switch means one more thing on your sink deck that you will need to wipe around as you clean up around the sink.

NOTES:

check dimensions!
