Denver Plumbing Guide - How to Install a Sink

Installing a sink is a relatively simple job, but for someone with little to no plumbing experience, it can seem like a daunting task at first glance. But not to worry! Our Denver fixture plumbing experts have put together a handy step-by-step guide that can eliminate the guesswork and get you on the right track.

Installing a Kitchen or Bathroom Sink

  1. Measure your existing sink: Your first step is to measure your existing sink. If your new sink is a different size than your current unit, you may need to modify your countertop and/or plumbing system to accommodate for its dimensions.
  2. Remove the old sink: Before you start, take a photo of your current plumbing configuration for reference. Turn off the hot and cold water supply lines using their respective valves under the sink. If you are unsure, shut the main water line to your house to be safe. Be sure to turn on the faucet to relieve any remaining water pressure.  Next, disconnect the water supply lines, garbage disposal unit, and dishwasher drain lines. Always keep a bucket underneath to catch any water that may escape during this process. Finally, loosen the metal clips fastening the sink to the countertop under the sink and around its edge. Cut any existing caulk with a utility knife and carefully lift away the old sink.
  3. Install the new sink: After carefully cleaning away any remaining caulk from the countertop with a putty knife, lay the new sink in the countertop hole and make sure it fits securely. Once a proper fit is verified, remove the sink and attach the new clips. Install the faucet and any additional components such as soap dispensers to the new sink. Secure the drain strainer using a small amount of plumber’s putty around its edge and press it firmly into place. Use a soft towel to wipe away any excess putty. If you have a garbage disposal, use a screwdriver to install the mounting bracket to the bottom of the sink according to manufacturer instructions.
  4. Add caulking: You are now ready to secure the sink in its final position and add silicone caulking. Apply a thin bead of silicone sealant around the bottom edge of the basin and lower it into the countertop opening. Make sure it is aligned squarely.
  5. Final steps: From the underside of the sink, rotate the attachment clips outward and tighten them. Re-attach the water supply lines, dishwasher drain line, and garbage disposal unit to the new sink. Make sure the disposal discharge pipe is connected to the sink drain pipe and reattach the P-trap. Add one final bead of silicone sealant along the top perimeter of the sink, reconnect the garbage disposal power, and turn the water back on. That’s it – you’re done!
