Understanding Your Plumbing System

Your home's plumbing system is critical for daily comfort and health. Understanding how it works helps you identify and prevent problems before they become expensive.

Main Components

  • Supply Lines: Deliver hot and cold water to your fixtures
  • Drains: Remove wastewater from your home
  • Vents: Allow air into drains for proper flow
  • Traps: Prevent sewer gases from entering your home

Common Plumbing Problems

Leaky Faucets

A dripping faucet wastes 3,000 gallons annually. Most leaks are caused by worn washers that cost less than $1 to replace.

Clogged Drains

Hair and soap buildup are common causes. Use a plunger, snake, or enzymatic drain cleaner before calling a professional.

Maintenance Tips

"An ounce of prevention is worth a pound of cure." Regular maintenance prevents costly emergencies.
  1. Inspect under sinks monthly for leaks
  2. Use drain screens to catch debris
  3. Run hot water regularly to clear pipes
  4. Check water pressure (should be 40-60 PSI)
  5. Have a professional inspection yearly
