I hired him to put handrails in my shower. Then I hired him to install exhaust fans in 20 houses. Then I had him do a French drain. Then he done some power washing. The man can do about anything by being so young he is learning very fast. I would recommend him for about anything you need done.

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.

Regular use helps keep interior dishwasher parts functioning properly and the interior clean. Try to run your machine at least once every two weeks as part of your dishwasher cleaning schedule.

Every six months, running two cups of white vinegar through your dishwasher (place the vinegar where you put detergent) will help deep clean the unit to boost performance.

Only if the dishwasher isn’t made of stainless steel. The corrosive chemicals in bleach will stain stainless steel and can also cause further damage. To stay on the safe side, stick with an extra cycle of vinegar to banish any lingering odors.

Not all dishwasher noises are signs of trouble, as dishwashers naturally make sounds during operation. Normal sounds for a functional dishwasher include humming, swishing, and sloshing. However, if you hear problematic noises such as pounding, drumming, grinding, or rattling, it could be a sign of an underlying issue, and you should consider having a technician inspect your appliance.

Most repairs take 1-3 hours, but complex issues requiring part replacements may take longer if parts need to be ordered.
