Job done professionally and with care. I needed a new microwave installed and wired in an older home. The cabinet above needed to be replaced to accommodate the space. Rob was efficient, friendly, and did the job far better than I could. Will definitely be contracting him again for future work.

Dishwasher Installation questions, answered by experts

Any drain in your house requires a water trap to prevent sewer gases from entering the home. Dishwashers don’t have an internal water trap, so they must use an external P trap. The most convenient P trap for the dishwasher is already in the plumbing under your sink.

When a dishwasher discharges its wastewater, it uses a pump to quickly move a lot of water. If anything in the drain line or the garbage disposal impedes the high volume of water, it will back up into the sink through the drain or the garbage disposal. Following regular dishwasher maintenance tips like clearing clogs, keeping them cleared, and occasionally running the disposal will eliminate the problem.

Yes, you can use vinegar to unclog a dishwasher. To do so, combine 4 tablespoons of white vinegar with 4 tablespoons of baking soda and pour the mixture down your dishwasher’s drain. Let it sit for 15 minutes, then pour a cup of hot water down the drain to flush everything out. Finally, run a rinse cycle on your dishwasher to see if the clog is gone.

Your dishwasher drain hose may have a clog if your dishwasher is full of water, your dishes aren’t getting cleaned, or water takes a long time to discharge into the garbage disposal.

Professional services ensure correct installation, verify water-tight seals, and safely address plumbing and electrical connections in dishwashers.
