When to call, and what to do first

For the problems Ontario homeowners call about most, and why they come up here:

• Water Softener Installation

  Why it comes up in Ontario: Chino Basin groundwater is hard and leaves scale on fixtures and in heaters.

  Signs:

  White scale that clogs aerators and showerheads, spotty glasses, a noisy water heater

  Urgent when:

  Rarely urgent; scale builds slowly

  Before help arrives:

  Check your water hardness in the utility's water quality report

  Repair or replace:

  Hard water damaging heaters or fixtures: a softener protects them

• Water Heater Replacement

  Why it comes up in Ontario: Scale and Inland Empire heat shorten the life of garage water heaters.

  Signs:

  Water around the tank base, rusty hot water, a tank past 10 years

  Urgent when:

  The tank itself is leaking

  Before help arrives:

  Turn off gas or power and close the cold-water valve

  Repair or replace:

  Leaking tank: replace. Failed part on a younger tank: repair

• Slab Leak Repair

  Why it comes up in Ontario: Slab-on-grade homes hide supply leaks under the floor.

  Signs:

  Warm floor spots, sound of running water, a spinning meter

  Urgent when:

  Water surfacing through the floor or a large bill jump

  Before help arrives:

  Close the main shutoff if water is visible

  Repair or replace:

  One leak: spot repair. Repeated leaks: reroute the lines

Why Ontario homes need these repairs

Ontario, California pairs older neighborhoods near downtown and the airport with large new subdivisions in the former dairy land of New Model Colony. The city's utility pumps most of its water from the Chino Basin, so hard, mineral-rich water and slab foundations shape the calls plumbers get here.
