The drain exits the pump into the white corrugated line. (Expected)  Deciding the line was obviously too short,  they coiled it up a few times and ran it to a piece of copper pipe. (Unexpected) They then joined the pipe to unreinforced vinyl tube which then did the high loop to the sink plumbing 6-8 feet away.(Material choice, quite Unexpected)

Completely jacked up and lucky it didn't fail,  or within standards?

Seems fine , what's your concern? I think it's supposed to do a vertical loop or climb , but i could be wrong.

The concerns are an aging vinyl tube and double the connections. This being said, it could be normal.  I was expecting one long corrugated plastic hose. A 10 footer would have done it.

I’ve always put a vertical loop in the drain line . I don’t think it will work properly without it. I think my last one had a bracket near the top back of the dishwasher to hold the loop. Something about an air gap.

It loops vertically in the cabinet,  all the way up to the bottom of the countertop. There may  be 8 feet of vinyl between the sink plumbing and the short copper pipe they used as a connector.

Would you pay $300-500 for peace of mind for the rest of the time you'll be in the house? If so, have a plumber look at adding a p-trap near the dishwasher.

Is it not installed right beside the sink?

I'd prefer to see full diameter running to the side the garbage disposal to reduce the chance of clogging and the chance of leaks.

Nope.   Sink, inside corner then dishwasher. The inside corner is a decent sized 2 level turntable storage system.  The vinyl tube is visible in that area attached to the back walls. I'm estimating that a 10 foot line would be perfect.

Could be worse, this is how the dumb asses plumbed the drain line for our dishwasher. Lasted abut 6 months, then started failing to drain. Gee wonder why.
Nothing constructive to share just venting.

I'd just replace it with a proper non-collapsing line. May as well check your supply lines for it and the sink while you're at it. They're easy to replace and can prevent a headache in the future.

Ask the cat


Is this a new dishwasher installation?

If they left the installation guide read over it. It will clearly list the allowed connections electrical fill and drain. Read the contract provided by the store you bought it from

Installers have expensive insurance but very strict guidelines and coverage limitations

Water leaks scare them very much so any mention of water leaks they will listen and respond very quickly

Installers (most) are also very lazy. Little training and lazy. Not very bright

FYI, the install is 20 years old, but the dishwasher works fine.  A no frills analog timer controlled GE.   I removed the discharge line, and it wasn't brittle, but was quite stained ('cause vinyl is translucent).  Hard to tell if it's in the vinyl, or is just filth.  Basically a 6 foot corrugated line spliced into an 8 foot vinyl tube using a short piece of 1/2 inch copper pipe. Really, only 10 feet is needed, which is why they spooled up the corrugated plastic line.  

I'm going to replace the discharge, but no 10 foot corrugated plastic line is available at big box stores.  Is this something a plumbing supply store would have?  Could one just use a  5/8 inch ID heater hose, or does the detergent work on the rubber over time?

A dishwasher takes me about 35-40 minutes to install and I charge around $150.

Not all I bet

Or your area doesn't have houses that are more than 20yrs old

Floors that aren't flat

Sagging particle board countertops

Hard wired conduit wiring

Hard copper water supply

Cabinet openings that are smaller than the DW

Mice or cockroach infestation.  . . Etc

Any tubing the hardware has should work

You would need a high loop so water from the sink or disposer doesn't back up into the DW

ADD a leak alarm under the DW and where the water lines run
