Is it safe to extend the drain hose on my LG washer?
I would not extend the drain hose that is supplied with the machine.
However, what I have done in the past is to put a stand pipe closer to the machine with a U trap to prevent the smells coming back up.
I did that with 2&quot; pipe which solved the problem and never caused any back up for the machine.
The 60&quot; is usually taken as horizontal distance but the man ual will make that clear.
