Dishwasher hookups and refrigerator water lines in Grand Rapids
Quick answer: A dishwasher hookup in Grand Rapids takes 1 to 2 hours and costs about $150 to $350 in labor. A new refrigerator water line costs about $150 to $400, depending on how far the line runs from the nearest cold water pipe.
What does a dishwasher hookup involve?
A dishwasher needs three connections: hot water, a drain and power. The plumber runs a supply line from the hot valve under the sink to the dishwasher’s inlet valve. The drain hose runs up to a high loop or an air gap. From there it joins the sink tailpiece or the disposal. Power comes from an outlet or a hardwired junction box.
High loop or air gap?
Both stop dirty sink water from flowing back into your clean dishes:
- High loop. The drain hose is fastened high under the counter before it drops to the drain. It’s cheap and invisible.
- Air gap. A small fitting on the countertop. It’s the stronger protection, but it needs a hole in your counter.
Decide before the counter is cut. Adding an air gap hole to stone later is harder and costs more.
How is a fridge water line run?
The plumber taps a cold water line near the fridge, usually under the sink or in the basement. They run a line to a recessed valve box in the wall behind the fridge. A recessed box lets the fridge sit flush and keeps the valve easy to reach.
Grand Rapids homes with a basement make this simpler. The line can run along the joists and come up through the floor behind the fridge.

Common questions
Does my dishwasher need an air gap?
It needs protection against backflow, either an air gap on the counter or a high loop under the sink. Both stop dirty sink water from flowing back into the dishwasher. Which one is accepted depends on your local inspector and the code your city or township enforces, so ask your plumber before the counter is cut. An air gap needs its own hole.
What's the best tubing for a fridge water line?
Braided stainless or PEX lines hold up far better than thin plastic tubing, which can crack and leak behind the fridge where nobody sees it. Copper works too, but it kinks easily when the fridge is pushed back. Whatever you choose, add a shutoff valve at the wall so the line can be closed without moving the fridge.
Can the fridge line come from the sink?
Often yes. A plumber can tee off the cold supply under the sink and run the line through the base cabinets to the fridge. It’s usually the cheapest route when the fridge sits a few cabinets from the sink. If the fridge is across the room or on an island wall, a line from the basement is often cleaner.
