Step By Step Process To Replace & Install New Bathroom Sink
Many things can leak around your bathroom sink. The faucet & drain can develop leaks or sprayer hose can go bad. Once you regulate that those aren’t sources of water under the sink, the only miscreant that remains is a leaky sink. The metal present in some sinks is so thin that it conclusively wears out. Occasionally an accidental poke with any sharp object creates a hole. As you look for a replacement, select the sink that is the same in size as your old one to ensure it will easily drop into the opening on your countertop. Here are the items needed & steps to perform this task:
Things Needed For This Process
- Adjustable Wrench & Screwdriver
- Utility Knife & Gloves
- Faucet & Sink
- Supply Lines & Silicone Caulking
- Caulk Gun & Plumber’s Tape
- Water Supply Lines & Plumber’s Putty
- Drain & Drainpipe
Step 1: Remove The Old Sink
- First of all, you need to remove items from below your sink to give yourself easier access to your pipes. Turn off your hot and cold water shutoff valves by simply turning them clockwise. Turn on the faucet to run any water out of your lines. Disconnect your water supply lines from their valves by using an adjustable wrench.
- Now you need to disconnect your drain line that connects your old sink to your P-trap by simply turning the fittings counterclockwise using an adjustable wrench to loosen & remove them. Loosen & remove your sink basket as well.
- Next, look underneath the countertop along your sink’s edge for the clips or screws that might be holding it in place. Remove your screws or slide your clips out of the way. Stand in front of your sink & put your hand in your drain hole. Pull up on your old sink to pull it out of its opening.
- If it won’t come out then you need to carefully run your utility knife under the edge of your sink to break the silicone seal that holds it to your countertop. Set your old sink aside for disposal. You now need to remove any caulking and other matter that remains around your sink’s opening.
Step 2: Install The New Sink
- Firstly, install the faucet before you set your sink in place to make it easier to access your fittings. Slide the gasket, included with your faucet’s assembly kit, around the holes on the underside of your faucet. Alternatively, you can also run a bead of silicone caulk under your faucet’s base. Set your faucet and its base into the opening on your sink.
- Now you need to secure the faucet to your sink by using the washers & mounting nuts in its assembly kit. Tighten the nuts by your hand from underneath your sink. Finish tightening the nuts by using your adjustable wrench. Wipe off any extra caulk that oozes out from beneath your faucet’s base.
- The next thing is to wrap plumber’s tape around the threads of your water supply lines on the faucet. Now you need to attach your supply lines to the faucet. Tighten all the connectors by hand, then one-quarter turn with your adjustable wrench.
- Next you need to run a bead of plumber’s putty around the outside of your drain opening on the top side of your sink. Slide your drain basket into the opening. Secure your drain from below your sink by using nuts from its assembly kit. Wipe off any extra putty inside your sink.
- Wrap plumber’s tape around the threads of your drainpipe. Now, attach the drainpipe to your drain basket. Tighten the pipe by your hand then tighten one-quarter turn with your adjustable wrench.
- Next, attach the clips that hold your sink in place to the underside of your sink according to the manufacturer’s instructions. The clips are part of your sink’s assembly package. Next, simply run a bead of silicone caulk underneath the outer lip of your sink. Turn your sink over and then set it in place. Align your drainpipe with your P-trap. This step is very easier to do with the help of an assistant. Wipe off any silicone that oozes onto your countertop. Turn your clips so they fasten to the underside of your countertop & tighten them with your screwdriver. Tighten the fitting on your P-trap by hand.
- Finally, you need to attach your supply lines to your supply valves the same way you fastened them to your sink. Ensure to connect your hot water line to your hot water valve. Turn water on to your sink and also check for the leaks. If you see that the water dripping at any connection then you need to tighten the fitting no more than 1-quarter turn at a time until your leak stops.
Tips & Warnings
- If you have the garbage disposal then you need to disconnect it from your drain fittings, then leave the disposal on your sink until you pull out your sink. Disconnect the disposal from your old sink & install it onto your new sink according to the manufacturer's instructions.
- If you are going to install a double sink with no garbage disposal then you need to install both drains the same.
- If you have the garbage disposal then turn it off at your breaker box as well as unplug it before you begin this project.
- Always wear gloves to protect your hands when removing your old sink.
