Many everyday plumbing problems occur at exposed fixtures and connections, where a careful homeowner can make a safe repair with basic tools. These five jobs address replaceable parts and accessible blockages. Work slowly, keep old parts until the repair is proven, and know when a hidden leak or failed shutoff requires a licensed plumber.

Step-by-step instructions
- 1
Stop a running toilet
Watch a flush with the tank lid removed. If pressing the rubber flapper stops water entering the bowl, shut off the supply, flush the tank empty, and install a matching flapper. If water spills into the overflow, adjust the float so it stops about an inch below the tube.

Replace a dripping faucet cartridge
Close both under-sink shutoffs, open the faucet to release pressure, and cover the drain. Photograph each layer while removing the handle and retaining hardware. Take the old cartridge to a supplier for an exact match, coat new O-rings lightly with silicone plumber’s grease, and reassemble.

Clean a sink trap
Put a bucket below the curved P-trap. Support it while loosening both slip nuts, empty it into the bucket, and clean it with a bottle brush. Refit beveled washers in their original direction, hand-tighten, then add only a quarter turn if a joint weeps.

Restore a weak showerhead
Hold the shower arm steady while unscrewing the head. Soak the head in white vinegar for an hour, scrub the nozzles, and rinse. Wrap thread-seal tape clockwise three or four times around the arm, then reinstall the head hand-tight.
- 5
Free a pop-up drain stopper
Place a towel under the sink, loosen the pivot-rod nut, slide out the rod, and lift the stopper from above. Remove hair and buildup, then reinstall the stopper with its hole facing the back so the pivot rod passes through it. Test the lift lever and watch for drips.
Common pitfalls & troubleshooting
A slip joint still drips
Check that the washer is clean, centered, and facing the right direction before tightening slightly.
The showerhead still has weak pressure
Check other fixtures. Low pressure throughout the home needs broader diagnosis.
A faucet cartridge will not release
Confirm all retainers are removed and use the manufacturer’s cartridge puller rather than twisting harder.
Turn water back on slowly and observe every connection for several minutes. A dry fitting and a correctly working fixture are the real finish line.
