Expert Advice: 6 Common Bathroom Plumbing Jobs You Can Tackle Yourself, From Plumber Carly Carey

Carly Carey is a new mother and a third-year plumbing apprentice in Minneapolis—she’s about two years from taking the state test to become a licensed master plumber. It was during the pandemic that Carly, a middle school English teacher, decided to switch tracks. She now loves using her communication skills to demystify plumbing practices for the rest of us.

As a member of Matriarchy Build, Carly is in good company: an all-women team of pros in the building trades, the online platform offers consultations by Zoom that teach people to tackle basic house projects themselves: read about the group and its offerings in Remodeling 101: Advice from Skilled Tradeswomen.

Tired of steep plumbers’ bills, we asked Matriarchy Builder co-founder Lacey Soslow: are there common bathroom plumbing jobs we can tackle ourselves? She teamed us up with Carly, who responded that there’s no need to call at plumber, at least not at the get go, when faced with these six common challenges. Here’s her advice.

1. Unclog a Bathroom Sink

If you notice your sink is slow to drain, a straightforward way to unclog it is to remove the p-trap—the under sink piping that runs into the wall —and clean it out. To do this you’ll need a bucket, rags, and possibly a pair of pliers if the piping is metal. Place the bucket under the p-trap to catch the water that’s in it, and unthread the nut that connects the pieces. Using the rags, thoroughly clean out these parts, then reassemble the p-trap and run water to make sure nothing’s leaking.

Pro Tip: If the p-trap is old and made of metal, it might be difficult to remove, and might not be able to be put back together, so proceed with caution. If there’s no blockage in the under sink piping, the blockage is further down the line ad you’ll need a basic handheld plumbing snake (available at any hardware store) to remove it. Use caution if your fixture is old: a snake can puncture old and corroded pipes.

2. Replace a Sink Aerator

Have you had a sudden drop of water pressure from a sink? A clogged aerator might be the culprit. An aerator, comprised of numerous screens that are threaded to a faucet, adds air and saves water by regulating the flow from your faucet. Cleaning an aerator (or introducing a new one) is an easy way to make your bathroom greener.

Some aerators are recessed and need a specific aerator key to be removed. This key should have come with your faucet when you purchased it (and often gets taped to the cabinet or supply lines that connect to the fixture). Aerator keys are also sold at hardware stores. Some aerators can be unscrewed by hand, others require a crescent wrench or pliers to unthread. Once removed, rinse the aerator to remove the debris. You can also soak it in white vinegar and clean with a toothbrush or Q-tip, then reinstall. If a black rubber washer was removed, fit it back in place—it creates a seal to prevent dripping.

Pro Tip: Put a thin rag around the faucet to protect it from the crescent wrench. If a cleaned aerator doesn’t improve the water pressure, there’s an issue in the fixture or the waterlines, and you likely need a plumber.

3. Clean a Showerhead

Mineral buildup often plugs the tiny holes in a showerhead. For increased water pressure, use white vinegar as a showerhead cleaner: remove the showerhead (most screw off by hand), place it in a bowl of vinegar for at least 30 minutes, rinse, and reinstall the showerhead. Simple as that.

Pro Tip: If you don’t want to remove the showerhead, pour white vinegar into a plastic bag and put the bag around the showerhead secured with a twist tie.

4. Replace a Showerhead

In addition to the aesthetic benefits, a new showerhead can deliver better water pressure (while also conserving water by using less than your old one). To change your showerhead, you’ll need an adjustable crescent wrench and some plumber’s tape. First, remove the old showerhead by twisting it counterclockwise—if needed, use wrench to loosen. Next, clean the old plumber’s tape off the shower arm. Wrap new plumber’s tape around the threads of the shower arm and tighten on the new showerhead. Turn on the water to make sure there’s no leaking from the threads of the shower arm. If there is, further tighten the showerhead.

Pro Tip: Wrap a thin rag around the showerhead before loosening or tightening to protect it from scratches from the wrench.

5. Unclog a Shower Drain

As with sinks, if you find water pooling on the floor of your shower, you have a blockage in your drain pipes. First, try to unclog the drain with a barbed snake drain cleaner (these are plastic and about 30 inches long with barbs to aid in cleaning). Thread this through the drain of the tub/shower and pull out to remove hair and buildup. If the drain still isn’t clear, the blockage is further down the line.

Using a handheld snake will allow you to go deeper: insert the snake in the drain and feed the snake down. Crank the snake slowly and when you feel resistance you may have hit the blockage. Pull out the snake and the blockage along with it. You may need to do this a few times to fully get out all of the hair and other problem stuff. Run the water to see if the drain is cleared.

Pro Tip: If you’re unable to clear a drain with a barbed or classic snake, your blockage may be a more serious matter and you should call a drain cleaner or plumber.

6. Replace a Toilet Flapper

Is your toilet constantly running? A faulty flapper is likely the issue. The flapper is the rubber piece that lifts out of the way when the toilet is flushed before moving back in place. When the flapper fails to create a seal, water runs into the tank. To replace a flapper, turn off the water to your toilet, then flush the toilet to empty the tank. Next, remove the flapper and source a replacement flapper from the hardware store. To install the new one, attach the chain to the handle rod and the plastic tabs to the overflow tube.

Pro Tip: Bring your old flapper to the hardware store so you get the correct one. And make sure the chain to the flapper is the same length as the original. If the chain is too long it can get stuck under the flapper and cause a toilet to run.
