Same spot, same connections
Every job on this page puts a new appliance where an old one was, on the water, drain, power and vent that are already there. If the new appliance needs a different outlet or a new line, that's a job for an electrician or plumber.
Check before delivery
Measure the space and compare it with the new appliance. For a dishwasher, check that the shutoff valve under the sink turns. For a microwave, check there's an outlet in the cabinet above the stove.
Do the vent at the same time
Moving a dryer is the easiest time to clean the vent behind it. See dryer vent cleaning.
