dishwasherdraininstallationkitchens
Due to the issues with my kitchen cabinet layout, I can't have my Bosch dishwasher installed next to the sink. The only place where the dishwasher can fit into is the cabinet that's 17 feet away from the sink, but Bosch said the drain hose can be extended up to 12 feet.
Is 17 ft too far in this case? How damaging it could be if the dishwasher is installed too far from the sink?
There are no code regulations concerning the placement of a dish washer. As AWMoore mentioned, you will need to supply a hot water feed and a drain, with a trap. You will have to see where you can tie the drain into the system being sure to meet the drop to run ratio. You can most certainly find a place to make this connection in a basement. To save head space in the basement , the trap can be installed above the floor behind the dishwasher, and the dishwasher drain hose install there, kinda like a washing machine.
I can only think of three options here...
The first (less optimal) option, is to raise the discharge up and allow it to flow down to the drain connection. In this scenario, you'll want to have the discharge tube go up to an air admittance device (AAV) or air gap. From there it should flow downhill (1/4" per foot), until it reaches the garburator connection.
The other option, is to discharge the dishwasher to its own drain. Install a properly vented standpipe near the dishwasher, and connect the discharge tubing to that (follow local plumbing codes).
The last option is to run a drain line under the floor, and attach to the sink drain below the floor. Install a trap near the dishwasher, and run a proper drain that tees into the sink drain (follow local plumbing codes).
Best Answer
You can put the dishwasher wherever you want.
You will have to provide it with water and a drain that meets code - and it's not at all likely that you can run 17 feet to join the sink drain while meeting code. So you'll have to arrange plumbing to serve the water input and drain output needs of the dishwasher where you want to put it, independent of the sink.
