Serrano Heights was developed more recently than most of Orange. Homes tend to be larger, built on slabs on hillside and terraced lots, with copper or newer plastic supply piping and water heaters in attached garages. Some have high-capacity tanks, and some have tankless units or more than one heater serving different parts of the house.

Newer heaters still need maintenance. Hard water affects them the same way it affects older ones, and a tankless unit that has never been descaled can start throwing error codes within a few years. Larger homes also put more demand on their heaters, so sizing matters at replacement time.

Maintenance checks for newer heaters

  • Tankless: has it ever been descaled, and are service valves installed?
  • Tankless: is the inlet screen clean?
  • Tank: when was it last flushed?
  • Both: are straps snug and the vent secure?
  • Is there a recirculation pump, and is it working as intended?

Ask a plumber

  1. How often should our tankless unit be descaled?
  2. Is the recirculation setup affecting the heater's wear?
  3. When it's time to replace, should we keep the same capacity?

Common questions

Do newer homes still need water heater strapping?

Yes. California requires water heaters to be braced against earthquakes regardless of the home's age.

Why might my water provider differ from neighbors in central Orange?

Water service boundaries don't always match city neighborhoods. Your bill shows your provider.

Is a recirculation pump hard on a tankless heater?

It depends on the setup. Ask a plumber whether yours is configured for the unit.
