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 West Covina: What to Know
The Water
Suburban Water Systems
Suburban Water Systems supplies most of West Covina with a blend of Main San Gabriel Basin groundwater and imported water, and the groundwater side runs 16 to 18 grains per gallon. If your shower doors spot within a day of cleaning, that's the mineral load a tankless heat exchanger lives with full time.
The Houses
West Covina was one of the fastest-growing cities in America in the 1950s, and its housing shows it: tract ranches whose water heaters have been swapped like-for-like three times since. A conversion here is the chance to finally fix the venting and gas sizing properly.
