If you think your old sink is not big enough or the function is no longer suitable for your needs, perhaps you have to update it.
At present, more and more newly designed Sinks make life more convenient, but replacing Sinks seems to be a time-consuming and expensive thing. Actually, it is not.
Now let me introduce you to a simple replacement method.
Step 1 – Measure the old sink
Measure your existing sink. If your new sink has different dimensions and drain location(s) than the unit it will replace, you may need to modify the countertop opening and / or plumbing.
For best results, make a drawing of your old sink with all measurements including distances from the sink wall to the drain center to use as a shopping aid and reference.
Or you can remove your old sink, take it to Lowe’s, and ask a Lowe’s associate to help you select a replacement unit.
Step 2 – Remove to old sink
1) Turn off both the hot and cold water supply lines.
2) Turn on the faucet to relieve water pressure in the lines.
3) Use adjustable wrenches to disconnect the water supply lines to the faucet.
4) Have a small bucket ready to catch any water left in the supply lines and drainpipes as they are removed.
If you have a garbage disposer or dishwasher drain line, turn off the circuit and remove them
5) Locate the metal clips under the counter around the sink’s perimeter. Loosen them with a screwdriver, open-end wrench or socket wrench and swing them toward the sink bowl.
6) Cut the caulk around the sink with a utility knife.
7) Push the unit from underneath and lift the old sink away.
8) Use a putty knife to remove grime, caulk and old plumber’s putty from the countertop.
Step 3 – Install new sink
1) Set the new sink in the countertop hole to verify that it fits. If necessary, modify the countertop opening using a jigsaw, router or tile cutter. If your new sink has larger dimensions than the current countertop opening, follow the cutting template of the new sink to create a new cutout.
2) Remove the sink from the countertop hole to attach the clips, turned inward toward the sink bowl.
3) Install the faucet and additional components.
4) Apply a small bead of plumber’s putty around the drain strainer and install the strainer, pressing firmly against the putty.
5) Tilt the sink to its side to place and secure rubber gaskets and threaded flange to the underside of the sink drain. Repeat this for additional drains without disposers.
6) Remove excess putty with a soft towel.
7) Apply a bead of silicone sealant to the edge of the basin.
8) Lower the sink into the countertop opening, aligning squarely.
9) From below the sink, rotate the metal attachment clips outward and tighten the nuts or screws.
10) Attach the supply lines to the water connections of the faucet and the supply pipes. Tighten the connections, taking care not to strip the threads or overtighten.
11) Connect the disposer discharge pipe to the sink drain pipe and reattach the P-trap.
12) Apply a small bead of sealant to the perimeter of the sink.
13) Reconnect the power to the disposer. Turn the water on and check for leaks.
That’s all the steps of replacement. You can actually do it by yourself.
You just need some special tools. I believe you will enjoy it because it can save a lot of money for hiring someone to do it for you.
