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 Glendora: What to Know
The Water
City of Glendora Water Division / Suburban Water Systems (some streets)
Most of Glendora is on city water, a blend of local basin wells, San Gabriel River surface water bought through the Covina Irrigating Company, and imported supply. Some streets are on Suburban Water Systems instead. Either way it runs hard. White crust on a two-year-old fixture is normal here, which tells you what's happening inside a heat exchanger.
The Houses
Glendora ranges from 1950s tracts near Route 66 to large custom homes up the foothill streets. The custom homes often have long pipe runs from the water heater to the far bathrooms, so recirculation comes up on almost every foothill quote. It's the difference between instant hot water and a 45-second wait.
