When to DIY vs. When to Hire a Professional Plumber

Some plumbing issues can be tackled with basic tools and a bit of know-how, but others require the expertise of a licensed professional. Knowing the difference can save you time, money, and potential headaches.

Plumbing Issues You Can DIY

• Clogged Drains: Use a plunger, drain snake, or a non-corrosive drain cleaner to resolve minor clogs.

  Running Toilets: Replace a faulty flapper or adjust the float mechanism in the tank.

  Leaky Faucets: Tighten loose parts or replace a worn-out washer or O-ring.

  Low Water Pressure: Check and clean clogged aerators or showerheads.

  Replacing Fixtures: Swap out old faucets or showerheads with basic tools if you feel confident.

When to Call a Professional Plumber

• Burst Pipes: Immediate professional intervention is needed to prevent water damage.

  Sewer Line Issues: Backups, foul odors, or slow drains could indicate serious sewer problems.

  Water Heater Repairs: If the unit is leaking, not heating properly, or showing error codes, hire a professional.

  Major Installations: Jobs like re-piping, gas line installation, or new plumbing for renovations require licensed expertise.

  Persistent or Complicated Problems: If a DIY attempt fails or the issue recurs, a professional’s insight is crucial.

  Hidden Leaks: Water stains, mold, or unexplained increases in water bills may indicate hidden leaks that need expert detection.
