That is exactly the range where scale starts coating tankless heat exchangers

For readers comparing the Best Water Softener San Jose, CA options, that distinction matters because the city’s supply is treated to meet EPA health standards, yet many neighborhoods still receive moderately hard to hard water that leaves scale on fixtures, shortens appliance life, and makes soaps work harder.

In this city, a blend of imported Sierra and Delta surface water, local reservoir supplies, and groundwater delivered through Valley Water and retail utilities such as San Jose Water can still leave enough dissolved calcium and magnesium to create scale, spot glassware, and shorten appliance life. That is why the search for the B

San Jose water rarely shocks people at the tap, but it often surprises them inside the house. Based on recent San Jose Water quality reporting, hardness can range from roughly 100 to 240 mg/L as CaCO3 , which converts to about 5.8 to 14.0 grains per gallon (GPG) by dividing by 17.1.
