Plumbing in Morgan Hill
One water supply, and it is hard
Many cities in the county blend imported water with groundwater. Morgan Hill relies on groundwater alone, and the minerals in it come out as white scale wherever water is heated or left to dry. Tank heaters fill with sediment, tankless heat exchangers scale up, and faucet aerators clog.
None of that is dangerous, but it is expensive over time. A softener protects the whole house, while regular flushing protects a heater on its own. We help you choose based on how much scale you are seeing and how long you plan to stay.
Water and pipes
How hard Morgan Hill water is
Morgan Hill runs entirely on groundwater from its own wells, and its hardness averages about 267 mg/L, which is in the very hard range. Homes here see scale faster than homes on imported supply elsewhere in the valley. Tankless units usually need descaling at least once a year, and tank heaters benefit from regular flushing to clear the sediment that settles at the bottom.
Houses and pipes
Morgan Hill houses
Much of Morgan Hill was built in later decades than central San Jose, so plastic and copper supply lines are common and galvanized pipe is less of an issue. The calls here lean toward water treatment, water heaters and fixtures rather than repipes.
Larger lots on the edges of town can have long service lines and outdoor plumbing, which adds irrigation backflow devices and main line leaks to the list.
