Draining Dishwasher Through Floor

Use a couple of towels to soak up the last portion of the water.

Draining dishwasher through floor.

I will drill holes through the joists just under the floor to the sink. The pipe it is connecting to is larger than the dishwasher drain pipe and the air inside the pipe will provide enough air for venting. There is a hole drilled from the basement right below the dw so the water hose going in and the drain hose are through that opening the drain hose then is routed to a p trap nearby but it is indeed also accessed from just below the floor. When the dishwasher door is closed the rubber seal going around the entire interior door is what seals the water inside.

If the disposal unit contains unground food or if food sludge settles in the drainpipe below. If this gasket gets ripped brittle or worn out water will overflow onto the floor. Run your garbage disposal. Moving a dishwasher full of water can be messy.

The venting is required to prevent air lock when draining. My idea is to drill a hole in the floor and run it right under the floor. If you direct connect below the floor and the line becomes blocked most likely the sewage will back up into the dishwasher remind me if i ever visit not to eat or drink from your dishes. When the appliance man was here we let water fill the dw then we opened the dw and watched it drain out.

If pipe above water line has build up knock it off with a drain brush. When i get there i will raise the line to the high loop to a level with the top of the dishwasher the down to the tap in the drain before the p trap. Dishwasher drain under the floor dishwashers require air gaps above the flood rim of the fixture receiving the discharge. Use cups or other containers to scoop out the water and transfer it to the sink drain.

Make sure water at water line is fresh and if it s a floor sink clean it and run drain basket through dishwasher. Protect the floor under and in front of the dishwasher with old towels. The drain hose from your dishwasher empties into the garbage disposal drain. Dishwasher door gasket fault if water or soap suds escape past the dishwasher door and onto the floor the sealing gasket on the dishwasher door is most likely worn out and needs to be replaced.

If you loop the drain under the cabinet and strap it up high before going through the floor this will provide the trap needed.
