Water Filtration FAQs

What is the hardness of LA water?
Los Angeles water typically measures 275-400 mg/L (16-23 grains per gallon), classified as very hard. This accelerates scale buildup in pipes, water heaters, dishwashers, and fixtures.
Do I need a water softener or a filter?
Water softeners address hardness (calcium and magnesium). Filters address chlorine, sediment, taste, and odor. Many LA homeowners benefit from both — a whole-home softener plus a carbon filter or reverse osmosis drinking system.
How long does installation take?
Most under-sink filters take 1-2 hours. Water softener installation typically takes 2-4 hours. Whole-home systems may take a half or full day depending on your plumbing configuration.
Will a water softener affect my water pressure?
A properly sized and installed softener has minimal impact on water pressure. We assess your home's flow rate before recommending system size to ensure no pressure loss.
How often do filters need to be replaced?
Under-sink filter cartridges typically last 6-12 months. Whole-home carbon filters last 1-3 years. RO membranes last 2-5 years. Water softener salt should be refilled every 1-3 months depending on household size.
