Is a disposer required for dishwasher permanent installation?
I have had several houses with a dishwasher but not a garbage disposal. I don't think it really changes the installation that much... the dishwasher waste pipe connects to the sink drain before the trap.



If you want to plumb the dishwasher somewhere there isn't a sink already, you need to install a trap &amp; standpipe, similar to the way a washing machine is done.
