How to Relocate a Kitchen Sink With a Concrete Slab
- 1). Remove all fitting and fixtures in the kitchen, such as the sink, flooring and cabinets. Remove cups and plates from cupboards if using a jack hammer because the vibrations can cause breakages. Locate the drain edge and ensure that the pipes line up.
- 2). Draw a line on the floor and cut a 2- by 3-inch wide trench away from the wall on the concrete slab, using a saw or jackhammer. Use a tent like temporary enclosure around the area to prevent dust from spreading.
- 3). Match the extension pipe so that it meets the horizontal drain pipe. Cut the length of UPVC pipe, leaving an extra foot longer to be safe. Wrap the pipe with white plastic foam, covering it with about 50 percent of the foam.
- 4). Lay the pipe in the trench and match the pipe with the drain from the old sink and with the T-shaped pipe in the new sink. Attach the AAV Vent.
- 5). Run water through the pipes to test for leaks. Use sealant to the pipes make water tight if necessary. Pour concrete into the trench to seal it and let is stand for a few hours.
