Cupertino homes, up close
Rancho Rinconada is a 1950s neighborhood with many Eichler homes. Apple Park, Apple's headquarters, opened in Cupertino in 2017.
Many homes sit on slab foundations. Many mid-century homes keep the water heater in a garage or utility closet, where code may call for raising it off the floor. Most homes went up between the 1950s and 1970s as orchards gave way to tracts.
Sediment still builds up in tanks over time, so a yearly flush helps a tank run quieter and last longer. The San Andreas Fault runs through the hills west of the city.
Local rules
Water heater replacement in California is plumbing work, and plumbing licenses come from the Contractors State License Board, and state code requires seismic strapping. Replacing a water heater usually involves a permit from the City of Cupertino Building Division, plus code items like a temperature and pressure relief valve and proper venting.
Stevens Creek runs north from the Santa Cruz Mountains through the city. Your water bill comes from San Jose Water or Cal Water, depending on the neighborhood, sewage is handled by the Cupertino Sanitary District, with treatment at the San José-Santa Clara Regional Wastewater Facility, and the City of Cupertino Building Division issues building permits. Memorial Park is the city's central park and hosts summer events.

Quick answers
What is the relief valve for?
The temperature and pressure relief valve releases water if the tank gets too hot or pressurized. It should never be capped or plugged.
Do you cover Inspiration Heights and Creston?
Yes, as long as a pro is available. Cupertino ZIP codes 95014 are in range, and that includes Inspiration Heights, Fairgrove, Jollyman and Oak Valley. Share the street name when you call so we can check the right part of town.
How often should a tank be flushed?
Once a year is a common rule of thumb, more often where water is hard. Ask the pro to show you the drain valve so you know where it is.
What should I tell the specialist?
Share the brand, capacity and fuel type from the label, the approximate age and what you're seeing.
Is a tankless water heater worth it?
It can save space and run longer showers, but it costs more up front and may need a bigger gas line or new wiring. A pro can tell you what your home would need.
Keep pets in another room while the pro works.
