Taking care of minor plumbing issues on your own can save time, money, and the inconvenience of waiting for a professional. Many common problems—like clogged drains or leaky faucets—can be fixed with basic tools and a little know-how. But not all plumbing jobs are suitable for DIY, and knowing when to call a professional is just as important as knowing how to make small repairs.
This guide will walk you through some of the most common plumbing fixes you can do yourself, and help you recognize the signs that it’s time to bring in an expert.
Easy DIY Plumbing Fixes
1. Fixing a Leaky Faucet
A dripping faucet is not only annoying but can waste gallons of water over time. In most cases, the culprit is a worn-out washer or cartridge.
What you’ll need:
- Adjustable wrench
- Screwdriver
- Replacement washer or cartridge (specific to your faucet model)
Steps:
- Turn off the water supply to the faucet.
- Remove the handle and unscrew the faucet assembly.
- Replace the worn-out washer or cartridge.
- Reassemble the faucet and turn the water back on.
Tip: Take the old part to a hardware store to get the exact match.
2. Unclogging a Sink or Shower Drain
Slow-draining sinks and showers are usually caused by hair, soap scum, or grease buildup.
Tools you can use:
- Plunger
- Drain snake or auger
- Baking soda and vinegar (for light clogs)
Steps:
- Remove the drain cover.
- Try plunging first—seal the overflow hole with a cloth if applicable.
- Use a drain snake to pull out the clog if plunging doesn’t work.
- Pour a mix of baking soda and vinegar down the drain, followed by hot water to help clear minor buildup.
3. Replacing a Showerhead
Swapping out an old showerhead is one of the simplest plumbing upgrades.
What you’ll need:
- New showerhead
- Teflon tape
- Adjustable wrench
Steps:
- Unscrew the old showerhead.
- Clean the threads and wrap them with Teflon tape.
- Screw on the new showerhead by hand, then tighten with a wrench if needed.
4. Running Toilet Repairs
If your toilet keeps running, it’s likely due to a faulty flapper, float, or fill valve inside the tank.
Fixes include:
- Adjusting or replacing the flapper
- Checking the float height
- Replacing the fill valve
Most parts are inexpensive and easy to install with basic instructions.
When to Call a Professional Plumber
While DIY is great for small tasks, some plumbing problems require expert hands. Here’s when you shouldn’t go it alone:
1. Low Water Pressure Throughout the House
Low water pressure can signal a bigger issue, like a pipe leak, corrosion, or problems with the main water line. If cleaning out faucet aerators doesn’t help, it’s time to call a pro.
2. Major Leaks or Burst Pipes
If you have a sudden burst pipe or significant water leak, shut off your main water supply and call a plumber immediately. DIY patching is only a temporary fix for these situations.
3. Sewer Line Issues
Gurgling drains, foul smells, or sewage backups indicate problems in your sewer line. These are not DIY-friendly and require special tools and experience to fix safely.
4. Installing or Moving Plumbing Fixtures
Planning to install a new sink, toilet, or dishwasher—or move them to a new location? These projects involve water and drainage lines, and improper installation can lead to leaks or code violations.
5. Water Heater Problems
If your water heater is leaking, not heating water, or making strange noises, don’t try to fix it unless you’re experienced with gas or electric systems. Water heaters can be dangerous if mishandled.
Safety Tips for DIY Plumbing
- Always turn off the water supply before starting any repair.
- Use the right tools for the job. Improvised tools can cause more damage.
- Know your limits: If you’re unsure, it’s safer (and often cheaper in the long run) to consult a professional.
- Wear gloves and eye protection when dealing with dirty water or chemicals.
- Keep emergency plumber contacts handy, just in case.
Conclusion
DIY plumbing can be empowering and cost-effective when it comes to small repairs and routine maintenance. Fixing a leak, unclogging a drain, or installing a new showerhead are all great projects for homeowners with basic skills and tools. But for more complex issues, it’s best to rely on a licensed plumber to avoid costly mistakes.
Knowing the difference between a quick fix and a serious problem is the key to smart, safe home maintenance. When in doubt, call in the pros—and enjoy the peace of mind that comes with a job well done.
