7 Plumbing Problems You Can Fix Yourself — And When to Call a Plumber

Some plumbing problems are simple DIY fixes, but leaks, sewer issues, water heater problems, and recurring clogs are usually worth calling a plumber for before they cause damage.

Most homeowners are not sure when a plumbing issue is safe to handle themselves and when it is time to call a professional. This guide breaks down common problems, what you can check first, and when to stop before a small issue turns into water damage.

1. A Dripping Faucet

Try This First

  • Check if the handle is loose.
  • Look for a worn washer or cartridge.
  • Make sure the faucet is fully turned off.

Call a Plumber If

  • The leak continues after repair.
  • Water is leaking under the sink.
  • The fixture is corroded or damaged.

2. A Slow Leak Under the Sink

Try This First

  • Place a dry towel under the sink.
  • Look for the exact source of the drip.
  • Gently tighten a loose connection if obvious.

The Rule We Tell Homeowners

If a plumbing problem can cause water damage, sewer contamination, gas safety concerns, or keeps coming back after a simple fix, it is time to call a professional.

Frequently Asked Questions

When should I call a plumber instead of trying to fix it myself?

Call a plumber if there is water damage, a persistent leak, gurgling drains, low water pressure, sewer smells, or anything involving your water heater or gas connections.

Is a dripping faucet a serious problem?

A small drip may seem minor, but it can waste water and become worse over time. If replacing a washer or cartridge does not stop it, have it checked.

Can I flush my water heater myself?

Some homeowners can, but it depends on the age and condition of the tank. If the water heater is older, rusty, noisy, or has not been flushed in years, it is safer to call a plumber.

Why is my toilet gurgling?

A gurgling toilet can be caused by a clog, venting problem, or sewer line issue. If multiple drains are gurgling, do not ignore it.
