Sink and drain setups
Under a kitchen sink you will usually find hot and cold supplies, a drain with a trap, a dishwasher drain connection and, in many homes, a garbage disposer. Each joint is a place for a slow leak. Swollen cabinet bottoms and a musty smell are often the first clue.
When a sink is replaced, especially when a double bowl becomes a single deep basin, the drain outlet position often changes. That can mean reworking the trap arm and the connection at the wall. We make sure the trap has proper slope and stays within the distance code allows from its vent, so the sink drains quietly instead of glugging.
Dishwasher hookups
A dishwasher needs a hot supply, a drain and power. On the plumbing side we look at:
- A dedicated shutoff for the dishwasher supply, so it can be serviced without killing the sink.
- A braided or copper supply line in good condition.
- A high loop or air gap on the drain hose so dirty sink water cannot siphon back into the machine.
- A clean connection at the disposer inlet or a dedicated tailpiece.
New disposers come with a knockout plug in the dishwasher inlet. Forgetting to remove it is a classic reason a new dishwasher will not drain after an install.
Fridge water lines
Ice makers and water dispensers run on a small supply line, often tapped off the cold line under the sink. Old self-piercing saddle valves and thin plastic tubing are frequent leak sources, sometimes behind the fridge where nobody sees them for weeks. We replace them with a proper shutoff and a braided or copper line. Our article on signs of a hidden leak explains what to watch for.
Island sinks and venting
Moving a sink into an island is the plumbing question that comes up most in kitchen renovations. Water lines are easy; drains are not. A sink needs a vent, and there is no wall in an island to run one up. Code-approved approaches include an island loop vent and, in some cases, an air admittance valve where allowed. The drain also needs a route through the floor, which in a finished basement means opening the ceiling below.
Bring us in before the cabinets are ordered. Drain and vent locations can affect where the sink base goes, and moving a box on a drawing costs far less than moving it after install.
Plumbing changes in a renovation may need a building permit from the Town. We will tell you when the work you describe crosses that line. For the parts that sit on the counter, see faucet repair and installation, and for the unit under the sink, see garbage disposal service.
Aurora customers often ask
Can a kitchen sink be moved to an island?
Usually, yes. The drain needs a route and a code-approved vent arrangement. In a home with a finished basement, that often means opening part of the ceiling below.
Do you work with my renovation contractor?
Yes. We prefer to visit before cabinets go in so drain and supply locations match the layout.
