Water Heater Repair & Replacement · Highland, CA

Most water heater calls we get in Highland fall into one of two buckets: a unit that can still be repaired, or a tank that is too far gone and needs replacement. Our job is to figure out which one you are dealing with before we touch a valve. A lot of homeowners assume a cold shower means a new heater, but the fix is often a thermocouple, gas valve, heating element, or dip tube. Those are repair jobs, and they cost a fraction of a full swap.

The hard water around Highland, Redlands, and the East Valley Water District speeds up the timeline. Sediment bakes onto the bottom of the tank every time the burner fires. Over years that layer turns into a rumbling, popping crust that overheats the steel and burns out the lower element. If the tank is under 10 years old and the steel is still sound, a flush, new element, and anode rod replacement can buy you several more years. If the tank is dripping, rusty, or older than 12, replacement is usually the safer call.

When we do replace a water heater, we do not just drop in a new box and leave. San Bernardino County requires seismic straps, a drip pan, a properly routed T&P discharge, and an expansion tank on closed systems. Gas units need the right venting and a sediment trap. Tankless heaters need a correctly sized gas line, sealed exhaust, and a condensate drain. We pull the permit, meet the inspector, and leave you with the sign-off.

Tankless repair and replacement is a different game. A failed flow sensor, scaled heat exchanger, or bad control board can often be fixed without replacing the whole unit. But if the heat exchanger is cracked or the unit is out of manufacturer support, we will size a Navien or Rinnai that matches your household demand and gas line. We also descale tankless units annually, which is the single thing that separates a 20-year unit from one that fails in five.

If your water heater is popping, leaking, running out of hot water fast, or just not heating at all, Grand Plumbing will give you a straight answer. We repair when it makes sense, replace when it does not, and we do both with flat pricing and same-day service across Highland and the Inland Empire.
