This is a typical Insinkerator unit... great quality and robust... but, I seem to have water flow problems with then new twin level design... seems water is not draining fast enough into the plumbing and has a tendency to flow into my dishwasher .... never had this problem with my previous insinkerator... this seems to happen when water is constantly flowing into the unit...and it will fill and hold water.... not typical... must make sure the unit is running... this seems to help.... outside of filling up with water, it is flawless...
