Do this now: water heater leaking or out in Philadelphia

1. Smell gas? Leave the house and call 911 or PGW from outside. Do not flip switches or look for the leak. The Kansas Corporation Commission's gas safety page says not to use phones or switches near the smell.
2. Leaking: close the cold water valve on top of the tank. On an electric heater, switch off its breaker.
3. Relief valve pipe dripping: do not cap or plug it. This Old House says plugging the discharge pipe stops the valve from working.
4. Water on the floor near outlets: use the breaker only from a dry spot (Red Cross).
5. No hot water but no leak: check the breaker on an electric heater or the pilot on a gas one. HomeAdvisor says drafts can blow a pilot out.

Is it urgent? When a Philadelphia water heater cannot wait

A water heater is urgent when the tank body leaks, you smell gas, or the relief valve keeps discharging. HomeGuide says a leak from the bottom of the tank usually means the tank must be replaced, while leaks at fittings or valves may be fixable. No hot water in a Philadelphia winter, with 77.3 nights a year at or below 32 F (NOAA), is worth a same-day call. Lukewarm water or a rumbling tank can wait for a weekday.

Philadelphia water hardness depends on your plant

Philadelphia water hardness ranges from about 6 to 10 grains per gallon on average, depending on which plant serves you, PWD's 2025 water quality report shows: Baxter averages 101 ppm (6 gpg), Belmont 151 ppm (9 gpg) and Queen Lane 169 ppm (10 gpg), with Queen Lane reaching 270 ppm at its high. Harder water leaves more sediment, which HomeGuide links to popping and rumbling. A flush costs $75 to $250 nationally, HomeGuide says.

Water heater installation in Philadelphia: permit and rebates

Water heater installation in Philadelphia runs $800 to $2,000, Angi's July 2026 Philadelphia guide says, plus a City plumbing permit. The permit is $31 for a one- or two-family home ($37 otherwise), with a $100 nonrefundable filing fee credited to the permit and $3 City and $4.50 State surcharges. A licensed master plumber must oversee the work, and the City says water heater permits may be issued immediately when the contractor applies. Large water heaters may also need a permit from the Department of Public Health. PGW pays $200 toward a standard gas tank and $500 toward a tankless, power vent, direct vent or condensing unit. No federal credit applies in 2026: the IRS says 25C does not apply to property placed in service after 2025. See water heater replacement cost and tankless water heater installation.

Repair or replace a Philadelphia water heater?

Replace a tank that leaks from the body or is past its life: DOE says storage water heaters last 10 to 15 years and tankless about 20, and HomeGuide suggests replacing a tank over 10 years old or when the repair costs more than half of a new one. HomeAdvisor puts a replacement at $882 to $1,826 nationally. Philadelphia's median house was built in 1949, the Census Bureau says, so ask the plumber to check the vent and gas piping when a new heater goes in. CPSC urges a 120 F setting; at 150 F most adults get third-degree burns in about two seconds.
