Why this comes up in San Diego

San Diego's tap water runs 15 to 20 grains per gallon almost everywhere in the county. That's hard enough to scale a tank water heater and cut its life short. Whether you're in Clairemont, Poway, Chula Vista, or up in Carmel Valley, annual flushing is what actually keeps a heater lasting.

FAQ

Common questions

Is it worth repairing a 10-year-old water heater?+

Usually no. Once tanks pass 10 years, corrosion is doing the damage and replacement is the smarter call.

Why is my hot water rusty?+

Almost always corrosion inside the tank. Flushing may buy you time. Replacement is the permanent fix.

My tankless throws an error code. Can you fix it?+

Yes. Most codes trace back to venting, gas supply, scale buildup, or the flow sensor. All fixable.

Does San Diego's hard water really shorten water heater life?+

Yes, significantly. Countywide hardness runs 15 to 20 grains per gallon, and scale drops out of solution on the tank bottom. Without an annual flush, tank life drops from 12 to 15 years down to 8 to 10.

Do I need an expansion tank in San Diego?+

Yes. Most homes here have a pressure regulator, which creates a closed system. Code requires an expansion tank to absorb thermal expansion so your T&P valve doesn't dump.
