can i connect the drain pipe directly to the disposal ( not to the air gap ) and will this cause any problem ?

hi,
i try to replace a dishwasher.
i do see under the sink, there is another pipe connects the air gap to the disposal. i connect the drain pipe to the air gap under the sink, but when i turn on the dishwasher, the drain water comes out from the gap to the sink instead of draining to the disposal.
can you explain why ?

Can you use a pigtail so you can plug into the wall outlet instead of hard wiring with 12-2 romex into the outlet box?

Vicki E. I’m trying to repair a leak near the dishwasher at my son’s house. The water supply and drain hoses run through empty space under the cabinet. I wish I could see the hose so I can figure out if the leak is coming from a loose coupling, a split hose, or something else.
The hoses can run anywhere as long as the water pressure is enough to let hot water in, and the dish washer’s pump can push the used water out to the drain, without back-flow of sewage or sewer gas.
The Installer just didn’t want to get into carpentry work.

When we had a new dishwasher installed to replace an older model, the installer ran the drain hoses through the cabinet next to the dishwasher instead of through the empty space under the cabinet. He claimed that it was because all the new dishwashers are required to use less water and that to make this work the water supply and drain lines need to be above floor level. Is this true or did we get taken (again)? I lost cupboard space and am not happy about this. By the way, we live in the midwest and there is a basement below this area with open access to the basement ceiling/kitchen floor.

We are installing a new tall-tub dishwasher. The printed instructions say there must be clearance between the motor and the floor, but do not specify how much clearance. We have 1/8″ clearance when following instructions for a 34-1/4″ counter height. Is this adequate or does this create a safety hazard?

We are having issue with installation of new Bosch side mounted diswasher. Problem stems with “professional installers”…They can remove existing DW (currently have laminate tops–will be replaced with Corian) Pro-Installers state we are to have new counter tops replaced and then they will install new DW (side mount) but have the “counter top 1/2″ higher then existing” How? Does this make sense? We are NOT replacing the floor tiles or the base cabinets. Current DW was in place when floor was tiled and is subsequently “grouted” to the floor! Our choice is to do as instructed above (shim counter top & cabinets) or to “replace” floor!!! PLEASE ADVISE!!!

We are replacing laminate counters with granite counters. We are replacing our old dishwasher with a new dishwasher. The salesman at the granite counter company said we needed to get a side mounted dishwasher and to have it installed prior to installation of the granite countertop. The dishwasher installer advised us to remove the old dishwasher and install the dishwasher after the the granite installation. These are two different companies. Who is right in this? Should we install the granite countertops first or the side mounted dishwasher? Please answer soon.

Joe: the 3/4″ subfloor may be the problem. If you have the installation instructions for the dishwasher they should explain where the top-mount controls should appear (probably not visible with the door closed). Like Danny explains above, dishwashers come with adjustable feet that allow raising it to be flush under the counter. Be sure that yours are turned all the way in so the dishwasher is as low as possible. If they are and you can’t push it in and the feet are on the tile, then unless you temporarily remove some tile or raise the countertop, it won’t fit.

If the feet are on the subfloor but it’s not in far enough, then if you remove the subfloor you should be able to get the DW into that lower section, then raise the adjustable feet to be flush with the bottom of the counter. Then if it’s laminate on particle board you screw the brackets on the top of the dishwasher into the bottom of the board. If it’s a completely stone countertop then check your installation manual to see if the DW can be secured on the sides or what other advice they give.
