DIY Plumbing Tips & How-To Guides: Simple Fixes Every Homeowner Should Know

When plumbing issues pop up at home, they can be stressful—and expensive. But not every plumbing problem requires calling in a pro. With a little know-how and a few tools, you can tackle many common plumbing issues yourself. Here are some essential DIY plumbing tips and how-to guides to help you keep your home running smoothly.

DIY Plumbing Tips & How-To Guides

1. Know Where to Shut Off the Water

Before starting any plumbing repair, the first thing you need to do is shut off the water supply.

  • Main shut-off valve: Usually located where the water line enters your home (often in the basement or near your water heater).

  • Fixture shut-offs: Found under sinks or behind toilets—turn these clockwise to stop the water.

Knowing this can help you avoid major flooding if something goes wrong.

2. Unclog a Drain with a Plunger or Zip-It Tool

Chemical drain cleaners can damage your pipes over time. Try these safer options first:

  • Plunger: Works well for sinks and tubs—make sure there's a tight seal and plunge with firm, quick motions.

  • Zip-It tool: This cheap plastic strip can pull out hair and debris from bathroom drains in seconds.

Tip: Pouring boiling water down the drain can also help dissolve gunk (but don’t use it on PVC pipes).

3. Fix a Leaky Faucet

That constant drip isn’t just annoying—it can waste gallons of water.

Most leaky faucets are caused by worn-out washers or O-rings.
Here’s a basic guide:

  • Turn off the water.

  • Disassemble the faucet handle.

  • Replace the rubber washer or O-ring inside.

  • Reassemble and test.

You’ll need a screwdriver, wrench, and a replacement washer (available at any hardware store).

4. Repair a Running Toilet

A running toilet can waste hundreds of gallons of water a day.
Common causes include:

  • Worn flapper: Replace the rubber flapper inside the tank.

  • Float too high: Adjust the float to lower the water level.

  • Chain too tight or tangled: Make sure there’s a little slack.

Most repairs can be done with inexpensive parts from the hardware store and no tools required.

5. Prevent Clogged Drains with Regular Maintenance

  • Use drain strainers to catch hair, soap scum, and food scraps.

  • Once a month, flush your drains with a solution of baking soda and vinegar followed by hot water.

  • Never pour grease or oil down the kitchen sink—store it in a container and dispose of it in the trash.

🛑 When to Call a Professional

Some jobs are best left to the experts:

  • Burst pipes

  • Sewer line issues

  • Water heater problems

  • Major leaks or flooding

  • Gas line plumbing

If you're unsure, it's always safer (and cheaper in the long run) to call a licensed plumber.

Final Thoughts

Learning a few basic plumbing tricks can save you time, money, and stress. Start with simple fixes and build your confidence from there. And remember—maintenance is key. Taking a little time each month to check on your plumbing can prevent costly emergencies later.
