Before — The Electric Tank We Removed
The unit we took out: rusted jacket, weeping fittings and standing water under the tank — replaced before it flooded the space around it.
Water heater trouble in Sunnyvale? Same-day tank and tankless repair across the Heritage District, Cherry Chase and Ponderosa Park, flat-rate quoted before we start.
Sunnyvale water heaters generally live longer than their county neighbours, and the reason is the water. A large share of the city's supply is soft SFPUC Hetch Hetchy water, so tanks accumulate far less sediment than in San Jose or Cupertino. That changes the diagnosis: when a Sunnyvale heater fails at eight or ten years, the cause is usually a specific component — thermocouple, gas control valve, upper or lower element, thermostat, or a T&P valve that has started weeping — rather than a tank that has silted up and given out. Which means repair is more often genuinely worth doing here.
Soft water has one catch worth knowing: it can be slightly more aggressive toward the sacrificial anode rod. A heater that has run a decade on soft water may have a fully consumed anode and a tank that is only then starting to corrode. We check the rod on every service call, and replacing a $40 rod at year six is the cheapest thing you will ever do for a water heater.
Installation constraints in Sunnyvale come down to house type. The 1950s and 60s ranches in Ponderosa Park, Birdland and Raynor Park have garage or exterior-closet units where the alcove was sized for a slimmer tank of that era. Eichler homes around Fairbrae and Monta Loma's Sunnyvale edge have flat roofs, no attic and radiant slab heating, which rules out some venting approaches entirely — those need a unit chosen for the vent path, not the other way around. Replacements are permitted through the City of Sunnyvale with strapping, expansion tank and code venting.

Less sediment than the rest of the county. A failed part is usually just a failed part here, not a symptom of a dead tank.
Soft water consumes the sacrificial rod. We check it every visit — a cheap rod at year six prevents an early tank replacement.
Flat roofs, no attics and 1950s alcoves dictate which unit fits. We measure and check the vent path before quoting.

New electric tank water heater set in place — new flex connectors, expansion tank, drain pan and seismic strapping, then labeled with the install date.
Both trucks stocked with the common failure parts — water heaters, valves, and fittings — so most jobs finish on the first visit.
