One of the most common DIY plumbing jobs a homeowner will need to do is replace an old kitchen sink. It’s a simple way to spruce up the space or make your kitchen more functional. Whether it’s getting rusty, starting to leak, or you are just looking for an upgrade, you’ll eventually need to swap a sink in your home. With this handy guide, we’ll show you the simple step by step process to replace your sink like a pro.
What you will need
- A new sink
- Plumbers putty
- Silicone sealant or caulk
- Utility knife
- Pipe wrench
Removing your old sink
- Before you start removing your sink make sure to turn off the main water supply to ensure water doesn’t come flooding out when you disconnect your sink. Next, run the faucet to get all of the water out of the tap.
- Once the connecting water line is emptied of water, disconnect it. If you have a soap dispenser or spray nozzle with a dedicated water line, disconnect those as well.
- If your sink has a garbage disposal, you will also need to go to your circuit breaker and turn off power to the garbage disposal. Then, remove the garbage disposal from the sink.
- Next you will need to disconnect the drain pipe. Make sure to have a bucket underneath the pipe when you disconnect it to catch any remaining water.
- Once the drain pipe is disconnected, look underneath your sink. You will find a locking clamp that holds your sink in place. Loosen this clamp, and then gently cut the caulk in between the sink and countertop. Once the caulking is cut away you should now be able to take out your old sink.
- Finally clean any remaining caulk from the countertop.
Installing the new sink
- First, you will need to apply a new layer of caulk to attach the sink. Apply a layer of caulk around the edges of the hole where your sink goes.
- Next, place the sink carefully in to the hole in the counter, then press down firmly on it to set it in place. Wipe away any excess caulk that may be forced out.
- Once the sink is in place, carefully apply a thin layer of Plumbers Putty on to the underside of your new sinks drain. Afterwards put on a new rubber gasket followed by the sink flange.
- Next you will need to tighten the nuts at the bottom of the flange to secure it in place. Wipe away any Plumbers Putty that seeps out quickly before it hardens.
- Next, reconnect the drain pipe to the sink flange using a pipe wrench. Then, reattach the water supply line.
- Finally, turn the water back on and check to make sure there are no leaks.
As you can see, changing your own sink isn’t that difficult. It requires the right tools and a little bit of patience. Once you get it placed and confirm there are no links, you are likely to have a beautiful new sink for years to come.
