Ridged Copper Supply To Dishwasher ?

Philly Dude

On a service call last night I found a ridged 1/2" copper supply line going directly to the dishwasher. Seems like a pretty dumb idea to me. Vibrations from the machine could loosen pipe fittings. Not to mention that it is a pita to disconnect and reconnect. Anybody see this before ? I have to go back to the house for some other work, and I'm gonna cut off some of the ridged line and put a flex line to the dishwasher.

Until about 8 or 10 years ago
all I saw was either ridged or
soft copper water lines.

Seen a few.

They usually get cut out and a SS braided line installed.

Almost every dishwasherone I have ever come across in my area are soft copper lines. They set the dishwasher in & then ran the line, so you had to unhook it to pull it out. I always talk the homeowner into installing a new SS dishwasher hose along with new valve under the sink as you usually have to change the connections anyway & usually the valve leaks by.........

Wait until you run into a dishwasher with a gravity drain, with a galvanized water supply, installed before the last two floors (you have to cut them up in place to get them out) with a finished basement or no basement at all (condo). I have seen tons of them in my days of doing kitchens, I suppose they're not as common these days.

Many dishwashers years ago required 1/2" OD minimum so they would get enough volume of water to operate properly. Don't think that is so important anymore or at least I hope so as the flex supplies are very small.

What other name does the soft go by..

I can not recall, but it is a Number or a Letter.

Soft copper is also sold as refrigeration tube.

Where are the ridges on the tube that the OP was referring to?

.Well, you know...... He was seeking advise.

But it is up to us as Tradesmen, to give PROPER advice concerning Rigid Copper versus the Flexible Stuffs. Do you suppose he fixed it using his Ridgid Tools???

Sooner or later, with enough practice, he will get over that ridge and be well on his way to being a Plumber versus a Plummer!
