Whole House Water
Filtration System Installation
in Bay Area, CA

Does your tap water taste like chlorine? Do you see white scale buildup on your shower heads, faucets, and inside your dishwasher? Bay Area municipal water is treated with chloramine (a chlorine-ammonia compound) and carries 10 to 25 grains per gallon of hardness in many cities. That means every fixture, appliance, and pipe in your home is exposed to chemicals and mineral deposits every day. A whole house water filtration system treats the water at the point where it enters your home, so every tap, shower, washing machine, and water heater receives clean, filtered water.

At United Plumbing and Water Heaters, we install whole house water filtration systems including carbon filters, water softeners, sediment filters, UV disinfection systems, and multi-stage filtration setups. We serve Dublin, CA, Pleasanton, Livermore, and communities along the I-80 corridor up to Sacramento and Roseville. Our licensed plumber will test your water quality, recommend the right system for your specific contaminants, install the unit on your main water line with a proper bypass valve, and verify flow rate and pressure throughout the house after installation.

Whole House Water Filtration System Installation Bay Area

Signs You Need Whole House Water Filtration

Bay Area water is safe to drink by EPA standards, but that doesn't mean it's free of taste issues, mineral content, or trace contaminants. Chloramine is the primary disinfectant used by most Bay Area water districts, and unlike free chlorine, it doesn't dissipate by sitting in a pitcher. Hard water damages appliances, clogs aerators, and leaves scale on everything it touches. A whole house filtration system solves these problems at the source. If you notice any of the following, contact us for a free water quality consultation.

Chlorine Taste or Smell

If your tap water tastes or smells like a swimming pool, you're tasting chloramine. Bay Area water districts use chloramine because it lasts longer in the distribution system than free chlorine. A whole house activated carbon filter or catalytic carbon filter removes chloramine at the point of entry so every faucet in the house delivers clean-tasting water.

White Scale Buildup on Fixtures

White crusty deposits on shower heads, faucet aerators, and around the base of fixtures are calcium and magnesium from hard water. Hard water also coats the inside of your water heater tank, reducing efficiency and shortening its lifespan. A water softener or salt-free water conditioner installed on the main line prevents scale formation throughout the entire house.

Dry Skin and Hair After Showering

Hard water and chloramine strip natural oils from your skin and hair. If your skin feels dry or itchy after showering, or your hair is brittle and dull despite using good products, the water chemistry is the problem. Filtering chloramine and softening the water at the main line makes a noticeable difference within the first week.

Spots on Dishes and Glassware

Water spots and cloudy film on dishes, glasses, and shower doors are caused by dissolved minerals in hard water. The minerals are left behind when the water evaporates. No amount of rinse aid will eliminate the problem if the water itself is the issue. A water softener removes the calcium and magnesium before the water reaches your dishwasher.

Sediment or Particles in Water

If you see small particles, sand, or cloudiness in your water, sediment from aging municipal pipes or your own home's plumbing is making it through to your fixtures. A whole house sediment filter (typically 5 to 20 micron) installed before your other filtration catches these particles before they reach your faucets, appliances, and water heater.

Appliances Failing Prematurely

Hard water and sediment shorten the lifespan of water heaters, dishwashers, washing machines, and ice makers. Scale builds up on heating elements, clogs solenoid valves, and restricts water flow through small orifices. A whole house filtration system protects every water-connected appliance in your home and can extend their collective lifespan by years.

Frequently Asked Questions

Common questions about whole house water filtration installation in Bay Area.

How much does a whole house water filtration system cost?
A basic whole house carbon filter for chloramine and taste removal costs $1,000 to $2,000 installed. A water softener costs $2,000 to $7,000 installed. A multi-stage system combining sediment filtration, carbon filtration, and water softening costs $2,500 to $5,000. A whole house reverse osmosis system costs $4,800 to $8,000 installed. The total depends on your water quality issues, home size, flow rate requirements, and the complexity of the plumbing at the installation point. Contact United Plumbing and Water Heaters for an accurate estimate.
How long does whole house water filtration installation take?
A single-stage carbon filter or sediment filter on accessible main line plumbing takes 2 to 3 hours. A multi-stage system with a softener, carbon filter, and bypass valve takes 4 to 6 hours. If the plumber needs to reroute piping, add a drain line for the softener, or install an electrical outlet for a UV system, the job can take a full day. We complete most installations same-day.
What type of water filtration system do I need?
The right system depends on what is in your water. For chloramine taste and odor on Bay Area municipal water, a catalytic carbon filter is the most effective option. Standard activated carbon removes free chlorine but does not remove chloramine efficiently. For hard water scale, you need a water softener (salt-based ion exchange) or a salt-free water conditioner. For sediment and particles, a 5-micron sediment pre-filter protects your other equipment. For bacterial concerns on well water, a UV disinfection system is the standard solution. Our plumber tests your water and recommends the right combination based on the actual contaminants present.
Does a whole house water filter reduce water pressure?
A properly sized whole house filtration system should not cause a noticeable drop in water pressure. The key is matching the system's flow rate capacity to your home's demand. A system rated for 10 to 15 GPM handles most residential homes comfortably. If the system is undersized, or if the filter cartridge is clogged and overdue for replacement, you will notice pressure loss. A bypass valve lets you isolate the system instantly if you ever need to troubleshoot a pressure issue.
How often do whole house water filters need to be replaced?
Sediment pre-filters should be replaced every 3 to 6 months depending on sediment levels. Carbon filter cartridges last 6 to 12 months for cartridge-based systems. Catalytic carbon media tanks with a backwashing valve last 5 to 10 years before the media needs to be replaced. Water softener resin lasts 10 to 15 years but requires regular salt replenishment every 4 to 8 weeks. UV bulbs should be replaced annually. Your system's manual specifies the schedule, and we can set up a maintenance reminder for you.
What is the difference between a water softener and a water filter?
A water filter removes contaminants like chloramine, sediment, VOCs (volatile organic compounds), and other chemicals from the water as it passes through a filtration media. A water softener removes hardness minerals, specifically calcium and magnesium, using ion exchange resin. The resin swaps calcium and magnesium ions for sodium ions. A softener does not filter contaminants, and a filter does not remove hardness. Many Bay Area homes benefit from both, installed in sequence: sediment filter first, then carbon filter, then water softener.
Is Bay Area water hard?
Yes. Water hardness in the Bay Area varies by city and water district but typically ranges from 8 to 25 grains per gallon (GPG). Anything above 7 GPG is considered hard. Dublin, Pleasanton, and Livermore tend to have moderately hard to hard water at 10 to 20 GPG. San Francisco water from the Hetch Hetchy reservoir is softer at 1 to 3 GPG. Cities that blend multiple water sources may have hardness that fluctuates seasonally. Our plumber tests your water on-site so the system is sized for your actual hardness level.
Can I install a whole house water filter myself?
A basic single-cartridge filter housing on accessible copper or PEX pipe is a manageable DIY project if you are comfortable cutting into your main water line and soldering or using push-fit fittings. A multi-stage system with a softener, drain connection, bypass valve, and backwashing controller is significantly more complex. Improper installation can void the manufacturer's certification, cause pressure loss, or create leaks at the point of entry where your main line carries the highest volume. For most homeowners the cost of professional installation is well worth the guarantee that the system is set up correctly.
Does a whole house water filter remove PFAS?
Standard activated carbon and catalytic carbon filters reduce some PFAS compounds but do not remove them completely. A whole house reverse osmosis system or a specialized PFAS filtration media is required for effective PFAS removal. Under-sink reverse osmosis units rated to NSF/ANSI 58 are the most common residential solution for PFAS at the drinking water tap. If PFAS is your primary concern, we can recommend the right combination of whole house filtration for general water quality plus a point-of-use RO system for drinking water.
What brands of water filtration systems do you install?
We install systems from all major manufacturers including Pentair, Aquasana, Culligan, SpringWell, 3M, and Watts. We also install media tanks from specialty suppliers for custom configurations. We can install a system you've already purchased or help you select the right equipment based on your water test results, household size, flow rate needs, and budget.
