10 Signs You Need to Call a Plumber Now

Some plumbing problems can wait until Monday. These ten cannot — call a licensed plumber today.

  1. A spike in your water bill with no obvious cause. Often a slab leak or hidden supply line. Wastes thousands of gallons per month.
  2. Slow drain in multiple fixtures. Indicates a main line clog or partial blockage, not a single P-trap problem.
  3. Sewer smell inside the house. A dried trap or a broken vent. Methane is flammable.
  4. Discolored water from hot only. Anode rod gone, tank rusting from the inside.
  5. Visible water stains on a ceiling below a bathroom. Active leak you may not hear.
  6. Toilets gurgling when a sink drains. Main line restriction.
  7. Sewage backing up into the lowest drain in the house. Stop using water immediately and call.
  8. No hot water at all + pilot won't light. Thermocouple or gas issue — don't keep trying to relight.
  9. Cracked or wet supply line at any shutoff valve. Replace the valve before it lets go.
  10. A pipe that froze. Even if it hasn't burst, it might have micro-cracks. Have it inspected.

What a fair plumbing service call costs

  • Diagnostic / service call: $75–$200 (often credited toward the repair)
  • Toilet rebuild / replacement: $250–$650
  • Garbage disposal swap: $250–$450
  • Main line snake / camera: $300–$700
  • Hydro-jetting: $450–$900
  • Slab leak detection: $300–$650

How to keep small problems small

  • Replace washing machine hoses every 5–7 years (steel braided).
  • Know where your main shutoff is and test it once a year.
  • Install a $40 water leak alarm under each sink and the water heater.
  • Replace plastic supply lines under bathroom sinks with braided steel.
