Why San Gabriel Valley Water Is Hard on Water Heaters

Much of the San Gabriel Valley drinks local groundwater, and it's some of the hardest water in Los Angeles County. Arcadia's 2024 water quality report shows an average of 210 mg/L of hardness, about 12 grains per gallon, with some sources as high as 340 mg/L, close to 20 grains. Neighboring cities that pump from the same groundwater basins deal with similar hard water, and every one of those minerals ends up inside your water heater.

In a tank water heater, those minerals settle on the bottom as sediment, right on top of the burner. That's the popping and rumbling sound, and it overheats the bottom of the tank until it cracks and leaks. In a tankless unit, the same minerals build up as scale inside the heat exchanger, which leads to error codes, temperature swings, and a heat exchanger that fails years early.

At these hardness levels, a water heater that's never been flushed or descaled can lose years of life. A yearly flush or descale and a safety inspection costs a fraction of a new unit, and it's the difference between a water heater that lasts eight years and one that lasts twelve or more.

More Ways We Can Help

Navien NPE240A2 tankless water heater installed by Premier Flow Plumbing in Pasadena, CA

What To Expect

A maintenance visit usually takes about an hour. On a tank water heater, we turn the burner down, flush the sediment out of the bottom of the tank until the water runs clear, pull and inspect the anode rod, and test the temperature and pressure relief valve. On a tankless unit, we close the service valves, circulate a descaling solution through the heat exchanger, clean the inlet filter, and check the error history, venting, and condensate line.

Every visit also includes a safety inspection. We check the venting and draft so exhaust leaves the house the way it should, look over the gas connection, earthquake straps, and drain pan, measure your home's water pressure, and test your water hardness. High pressure and hard water are the two things that wear out a water heater fastest, so if either one is off, we'll show you the numbers and explain your options, like a pressure regulator, an expansion tank, or a water softener. You get a quick rundown of everything we found before we leave.
