Tips Before You Start

  • ✓ Shut off the main water valve immediately if you have an active leak — find it before you need it
  • ✓ Emergency plumbing calls cost 50–100% more — schedule routine repairs during business hours
  • ✓ Water heaters over 10 years old: repair costs over $400 usually means replacement makes more sense
  • ✓ Drain cleaning (snaking): DIY with a rental auger ($40–$60) before calling a plumber
  • ✓ Annual water heater flushing ($80–$150) prevents sediment buildup and extends lifespan 3–5 years
