5 Plumbing Repairs You Can Do Yourself

DIY plumbing repairs are simple fixes homeowners can safely complete without professional help. Common tasks include fixing running toilets, unclogging drains, replacing aerators, tightening P-traps, and replacing fill valves’all requiring only basic tools and 30 minutes or less. knowing which repairs you can tackle saves money on service calls (typically $90-$200/hour) while knowing when to call a licensed plumber protects your home from costly water damage.

At ABM Plumbing Company, we believe in helping homeowners understand their plumbing—so you know when a DIY fix is appropriate and when it's time to call a licensed plumber.

1. Fixing a Running Toilet

A running toilet is one of the most common and easiest plumbing problems to fix.

In many cases, the issue is a worn flapper or faulty fill valve inside the tank. Replacing these parts is inexpensive and usually takes less than 30 minutes.

If the toilet continues to run after replacing internal components, the problem may be more complex and require professional attention.

2. Unclogging a Slow Drain

Slow drains in sinks, tubs, or showers are often caused by hair, soap residue, or minor buildup.

Homeowners can often clear slow drains using a plunger, a drain snake or zip tool, or hot water and mild soap.

Avoid chemical drain cleaners, as they can damage pipes over time and make clogs worse.

3. Replacing a Showerhead or Faucet Aerator

Low water pressure in a single fixture is often due to mineral buildup in the showerhead or faucet aerator.

Removing and cleaning or replacing these parts can restore water flow and improve efficiency. This repair requires minimal tools and is a great beginner-level DIY task.

4. Tightening or Replacing a Leaky P-Trap

Leaks under sinks are often caused by loose slip nuts or worn washers in the P-trap.

In many cases, tightening the connections by hand or replacing a washer will stop the leak. Always place a bucket underneath before starting and avoid overtightening plastic fittings.

5. Replacing a Toilet Fill Valve

If your toilet refills slowly or makes unusual noises, the fill valve may be failing.

Replacing a fill valve is straightforward and usually doesn't require specialized tools. Just remember to turn off the water supply before starting and follow the manufacturer's instructions.

Know When to Call a Professional

DIY repairs are great for minor issues, but some situations require a licensed plumber.

Call a professional if you notice persistent leaks, water damage or mold, sewer odors, multiple clogged drains, or low water pressure throughout the home.

Attempting complex repairs without experience can lead to costly damage.
