Common Tankless Water Heater Problems We Solve in East Whittier
Three of the most common tankless water heater calls we get from East Whittier homeowners, with how we fix them:
Annual flush is overdue
Hard water in this part of California scales the heat exchanger fast. We descale yearly to keep efficiency up and warranty valid. Takes about 90 minutes.
Tankless wasn't installed correctly
Common installer mistakes are gas line undersized, vent run too long, and no condensate drain. We fix any of these to bring the unit up to manufacturer spec.
Considering switching from a tank to tankless
We size the unit, check your gas meter capacity, and quote a clean install with the gas, water, and venting all to code. Most homes can be converted in one day.

Tankless Water Heater FAQs for East Whittier
