Waking up to cold water or a leaking hot water tank requires experienced plumbing service. Heise's Plumbing diagnoses and repairs gas and electric tank water heaters across San Francisco & Peninsula.
From failed thermocouples and faulty heating elements to leaking pressure relief valves, Heise's Plumbing provides prompt, honest water heater diagnostic and repair services.
Hot water failures stem from pilot light outages, gas control valve malfunctions, broken thermostats, or burned-out electric heating elements. Our plumbers inspect your water heater systematically to identify the exact cause of cold water or fluctuating temperatures.
Leaking temperature and pressure (T&P) relief valves, flex lines, or brass shut-off valves create hazardous water pooling around water heater bases. We replace worn valves and flex lines promptly. If internal tank corrosion occurs, we provide clear replacement recommendations.

Top leaks often come from loose flex connectors or a failing shut-off valve. Bottom leaks usually indicate a weeping T&P valve or internal tank corrosion requiring tank replacement.
A pilot light that repeatedly goes out is typically caused by a dirty or faulty thermocouple, a blocked pilot orifice, or a malfunctioning gas control valve.
Standard gas and electric tank water heaters last approximately 8 to 12 years depending on water quality, maintenance, and thermal stress.
If your water heater requires a minor component repair (like a thermocouple or valve), repair is usually best. If the tank is leaking internally, replacement is more economical.
Many manufacturers recommend periodic flushing. Appropriate maintenance frequency depends on the water heater, local water conditions, usage, and manufacturer guidance.
