Common Questions

The questions every homeowner asks

Most of SoCal runs between 11 and 28 grains per gallon (gpg). Anything above 7 gpg is classified as hard. Inland areas like Thousand Oaks, Riverside, and Palm Springs regularly test in the 18 to 28 gpg range, which the EPA classifies as Extremely Hard.
