Has anyone had to extend their dishwasher drain line to reach disposal connection? What’s the best way/materials? My dishwasher is a corner cabinet away from sink cabinet, about 110″. Thanks.

Prescriptive codes don't address the connection at less common angles, so base the connection off more typical ones using bolts, structural screws, blocking, and steel tension ties.

I have the same deal, got 2 rubber dish washer hoses connected with a gray plastic barbed connector. Gotta think there's a better way, but it is still good after 15 years. The dishwasher still runs, but is falling apart and rusting out. All whirlpool stuff.
Yeah, gotta be careful plus keep your fingers crossed with the barbs, or you'll have a clog. If you use one you should use the largest diameter one that you can make fit, so the hole in it is as close to the hose diameter as possible.Better to replace the entire hose, and auto heater hose is probably a good choice -- it's designed for heat, pressure, corrosive chemicals, and oils, so should handle whatever you throw at it.

If you've got access underneith (crawl space or basement) you might want to think about giving the dishwasher its own drain instead of tapping into the sink.

Because of the layout, a standard dishwasher hose wouldn't quite reach our disposal drain connection. Have had those corrugated plastic dishwasher drain lines break after 10+ years, so I really didn't want that kind of drain hose anyway. Went to the auto parts store and bought 10 feet of rubber heater hose for a car of the proper inside diameter. At the most it gets extra warm once in a while, but never hot like a car engine; I figure it should last forever.
great idea.

As someone said about the heater hose. Connections between hoses plug quicker than any other spot in a drain hose.
Right when the hose leaves the dishwasher try to go as high and as quickly as possible then a down hill slope to the drain.
If you don't you will get alot of water(dirty) run back into your dishwasher when it shuts off and you will wonder why your dishes don't get as clean.

I have extended quite a few.
In my neck of the woods a dw airgap is required, & I do recomend them.
As mentioned rubber hose from an auto supply store is an industry standard.
If the factory one is too short, take it out do NOT use a coupler in the middle you're just asking for a spot to leak.
Replace with the rubber hose from point A to point B with no joints in between.
I've used the heater hose that everyone has mentioned also.
Now I use clear tigon tubing, poly, pick it up by the foot at home centers by the foot.
Just onother option.
I agree with replacing the whole run and not splicing.

My plumber has the correct drain hose in a large roll for just those situations. We are about to do one that is not only around the corner but another 18" beyond that. From what everyone has told me this will be no problem. We are going to install a conduit so that the hose can be installed ex post facto and removed/replaced if necessary. We will be removing the factory hose... too short.
