Why would you need a water line for a dryer? Unless you have a dryer like no other I know of, no water goes into a dryer. The only connection a dryer needs is an output vent and an electrical outlet to plug it into.

All dryers with steam need a water line or have a tank to add water. They can't use much water which is why I assume 1/4" line would work. Just wanted some input from someone who may know for sure.

Just as a anecdotal note ... there were non-vented condensing dryers many years ago that used cold water to condense the heat/moisture. Maytag, Bendix, even Whirlpool used the method. I vaguely recall mention of such a unit within the last few years (the noise of the drain pump turning on every few mins was mentioned as a potential objection) ... but condensing dryers nowadays typically use cool room air as the condensation method.

Umm....what does the dryer's install-portion of the manual say?
