wicked long dishwasher drain hose

[CheckItOut]

Found a dishwasher with a drain hose that went out through the floor, into the crawl space where it dipped down about 3' below the floor, then up again through the floor under the kitchen sink then attached to the drain. I'd guess the hose to be a good 20' long. I don't know that this is a problem but thought I'd throw it out there just in case. I'd think the pump may be worked a little harder due to the distance.

Mfr's instructions on 3 dishwashers I've installed spec. 6 foot max.

But all three units were Bosch.

I would just write it up and let my client's know that it will not likely drain completely, and that it will likely freeze/ burst in the crawlspace.
