10 Signs You Need to Call a Plumber Right Now

A 15%+ increase in your water bill with no change in usage is a reliable indicator of a hidden leak. Even a small pinhole at 60 PSI loses approximately 600 gallons per day. Compare bills month-over-month and year-over-year — if the spike doesn't match seasonal irrigation patterns, call for a leak detection assessment.

A single slow drain is usually a localized clog. Multiple slow drains in different rooms simultaneously indicate a main sewer line obstruction. This is urgent — a partial blockage that produces slow drains today becomes a full sewage backup quickly. A backup, where wastewater rises into showers and floor drains, is one of the most damaging events a homeowner can face.

Brown or reddish water from cold taps suggests corrosion inside iron or galvanized pipes. Rusty water from hot taps only points to a depleted water heater anode rod allowing internal tank corrosion. Neither condition is safe to ignore — corroding pipes contaminate supply water and will eventually fail.

Pressure loss at one fixture usually means a clogged aerator you can clean yourself. Pressure loss throughout the house — at every fixture simultaneously — indicates a supply line leak, a failing pressure regulator, or galvanized pipe that has narrowed internally from scale accumulation over decades.

A water stain is evidence of a leak inside the structure. Even a stain that looks dry typically has an ongoing slow source. Do not paint over water stains without finding and repairing the source first — the structural material behind the drywall may be saturated or growing mold.

Water movement sounds inside walls when all fixtures are closed almost certainly means a pressurized supply leak. Supply lines are always under pressure — any crack releases water continuously, not only when a faucet is open. Shut off the main water supply and call for emergency leak detection.

Persistent sewage smell from floor drains, cleanouts, or the yard near the sewer line indicates a venting problem, a dried P-trap, or a cracked sewer pipe leaching wastewater into surrounding soil. Sewer gas contains hydrogen sulfide and methane — health hazards at elevated concentrations that warrant immediate investigation.

Tank water heaters have a typical service life of 8–12 years. A unit over 10 years old producing rusty water, making rumbling sounds, losing heating speed, or showing moisture around the base is in the final stage of its service life. Proactive replacement costs the same as emergency replacement — without the flood damage.

Gurgling from a toilet when you run the washing machine, or bubbling in shower drains when the toilet flushes, indicates a drain venting problem or partial main line obstruction. Air is traveling through the wrong pathway in the drain-waste-vent system — left unaddressed, this causes drain failure throughout the house.

Green staining on copper joints, white calcium deposits on fittings, or orange rust on iron connections are signs of active corrosion at the weakest points in your supply system. Visible corrosion means the process is well advanced. A plumber can assess whether the section needs immediate replacement or targeted treatment.
