DIY: How to Replace a Sink

If you are looking to replace your old sink with a new one, GNH can help you through the entire process from start to finish!

To remove your old sink, begin by removing the drain and detaching the garbage disposal (if you have one). Next, turn off the water supply and remove the clips that hold the sink in place. You can now lift your old sink out.

Put a coil of plumber's putty on the drain basket and press it firmly in place. If you have a garbage disposal, install the mounting bracket for the garbage disposal.

Next, install the fixture face plate to your new sink. Drop the faucet through the center opening and tighten the retaining nut at the bottom. Pass one end of the sprayer hose through the bottom and attach the end to the mixing valve at the bottom. Screw the rinsing wand on the other end of the hose. Finally, attach the water supply lines to the fixture.

Apply a bead of silicone adhesive around the edge of the sink opening and set the sink in place. With some soapy water, wet your finger and smooth out the silicone. Lastly, reattach water supply lines and reattach the garbage disposal.
