Water filtration installation covers whole-house sediment and carbon filtration systems, under-sink reverse osmosis (RO) units, and multi-stage drinking water systems. Sacramento area water, while treated, can contain chloramine, sediment, and elevated TDS depending on the source. Whole-house systems protect all fixtures and appliances, while under-sink RO systems deliver purified drinking water at a single point. We install, connect, and test all filtration systems to ensure proper flow and filtration performance.

California Building Code

Whole-house filtration systems must include a bypass valve for maintenance. Reverse osmosis systems require an air gap on the drain connection per California Plumbing Code. The system must not reduce water flow below minimum fixture requirements.

Project Timeline

Water Testing & System Selection

20-30 min

Test incoming water for hardness, chloramine, TDS, and sediment levels. Confirm the filtration system is properly sized for the home's water flow rate and contaminant profile.

Installation Location Prep

30-45 min

Identify the installation point (after the main shutoff, before the water heater for whole-house systems). Mount the filter housing bracket to the wall and prepare plumbing connections.

Plumbing Connections

1-1.5 hrs

Cut into the main supply line, install the bypass valve, connect the filter system inlet and outlet, and install a pressure gauge to monitor filter condition.

Flushing, Testing & Walkthrough

20-30 min

Flush the new filters per manufacturer instructions, test water quality at multiple fixtures, verify flow rate and pressure drop, and demonstrate filter replacement to the homeowner.

Water Filtration System Installation — Frequently Asked Questions

Do I need a whole-house filter or just an under-sink system?+

A whole-house system filters all water entering the home, protecting appliances and reducing chloramine odor from showers. An under-sink RO system provides superior drinking water but only at one tap. Many NorCal homeowners install both.

How often do I need to replace filters?+

Sediment pre-filters typically last 3-6 months. Carbon filters last 6-12 months. RO membranes last 2-3 years. Sacramento's water quality means filters may need replacement on the shorter end of these ranges.

Will a whole-house filter reduce water pressure?+

A properly sized system causes only 2-5 PSI of pressure drop with clean filters. Clogged filters increase pressure drop — that's why we include a pressure gauge to tell you when it's time to change filters.

Does Sacramento water need filtration?+

Sacramento's water meets EPA standards but contains chloramine (a disinfectant), moderate sediment, and elevated TDS in groundwater areas. Filtration improves taste, removes chloramine odor, and protects appliances from sediment.
