Portable dishwasher with water lines under the sink?


Is it possible to install a portable dishwasher, with the water lines attached under the sink, instead of directly attached to the faucet? Is it feasible to have the water lines go through the cabinets, for around 8-10 feet, to the portable dishwasher? If so, does any of this adversely affect the performance?

I'm looking for an easy solution to adding a dishwasher to my dated kitchen, but I don't want to have water lines visibly coming out of the sink.


Background:

This is a small 1950s house, with original, formica cabinetry. They are dated, but are in good shape, so I am not eager to spend a fortune remodeling. I'm also considering cutting a space in the existing cabinetry and installing a conventional dishwasher. But this seems messy and potentially risky -- as I suspect that they won't cut smoothly, and I am no Bob Villa -- just a guy with a Sawzall. Is this something that a plumber can typically do, or is better not to even go down this path?

Re: Portable dishwasher with water lines under the sink?


The drain line would be a bigger concern than the supply line. All pumps have a rated capacity. You might exceed the capacity of the pump

At one time I once had my DW across the room from the sink but I tapped into the hot water and drain at the installed location.

Post some pics, drawing or more detail. A DW requires 24" (23.875) of width and the full depth of a cabinet (24").

Thanks! Sorry for the delay in responding. Here are a couple of pictures. You can see the edge of the sink on the left side, with the auxiliary faucet visible.

The proposed location of a portable dishwasher is in the spot that empty, closest to the camera. That's where the fridge normally goes. I'm also considering cutting out the area directly underneath the basket to install a regular dishwasher, but I'm afraid that it's going to be impossible to cut cleanly.

Whats on the other side of the sink?

That looks like a 27-30" cabinet to me. It is real hard to get clean cuts with them mounted in place.

Re: Portable dishwasher with water lines under the sink?


I just uploaded pictures of the underside of the sink, as well as the sink itself.

The other side of the kitchen sink is the bathroom sink. It's a 1959 house.

Is it feasible to add something like this GE portable dishwasher, but keep the hoses under the sink, and run them under the counter?

You can replace the stop valve on the hot water line with one of these http://www.homedepot.com/p/Eastman-5...51LF/205807847 and run a line inside the cabinets.

You drain line is something I do not know the answer about. It appears you have enough room to add a dishwasher tailpiece http://www.homedepot.com/p/Everbilt-...9816/205153966 . But whether the pump can move the water that far or not is a complete unknown to me.

Adding a washing machine style drain behind the portable, in wall or exposed is always possible if you can tie it into the drain below the floor. venting can be done using one of these http://www.homedepot.com/p/Everbilt-...9816/205153966 though they are not approved in all locations and are not approved for enclosure in walls.
