There are attachments for a garden hose that will try to push water through the line to clear a blockage. I don't like this idea since a hard blockage could cause water to go places it shouldn't, but others have had luck with these.
The hot water or vinegar will keep a line from clogging but won"t help much once it has clogged.
We like Munn's but I've seen other companies mentioned too.

I agree that using a garden hose to unclog a blockage is not a good idea. But, using a garden hose to flush the line that is not blocked will do a good job at removing gunk and debris from the pipe. My drain seems to accumulate a white chalky substance.
