Get Your Duarte Quote — (626) 602-9308🛑 Read this before you buy a tankless in the SGV: San Gabriel Valley groundwater features exceptionally high mineral hardness ratings. Running a high-efficiency tankless system across local infrastructure without a dedicated scale-inhibitor filter or an annual system flushing schedule will cause mineral scaling, reducing output and potentially voiding manufacturer warranties.

Installing in Duarte: What to Know
The Water
California American Water
California American Water serves Duarte entirely from Main San Gabriel Basin groundwater. Basin water in this part of the valley is very hard, typically testing in the mid-to-high teens for grains per gallon. No installer in our network will put a tankless in Duarte without a scale inhibitor, full stop.
The Houses
Duarte's housing stock is mostly compact postwar homes along the old Route 66 corridor, where the water heater shares a small garage or an outdoor closet. A tankless unit frees up that space entirely. Wall-hung outdoor models are a popular pick here.
