Is it true that dishwashers have to have a very low draining point as they
do not have the same pumping power as say a washing machine ? The reason I
ask is because the washing machine drains via the waste pipe directly under
the sink and I was just going to tee off into this, but have been told I
might not be able to drain the dishwasher adequately. Thanks in advance for
It sounds like your washing machine is not installed correctly (maybe it
is, I'm just guessing from what you said).
The dishwasher normally ties into the tailpiece right under the sink
basket via a vacuum breaker.
The only dishwashers I know of that require a low drainage point are some
models of commercial dishwashers or bar glass washers. Any residential
dishwasher I've seen is easily able to pump up to the top of the counter. If
all else fails, do as I do: go out to the garbage heap, find the box the
appliance came in, and remove the instruction book. Then read it! ;-)
