Types of Water Filtration Systems We Install
Different homes require different solutions. Crown Plumbing installs a wide range of water filtration and purification systems to match your specific needs.
Whole-House Water Filtration System Installation
A whole-house water filtration system installation treats all the water entering your home at the source. Every faucet, shower, dishwasher, and appliance benefits from filtered water — including the fixtures your family uses most.
Whole-house water filters help:
- Improve water taste and clarity
- Reduce sediment and contaminants
- Protect plumbing and appliances from buildup
Water Purifier Installation (Reverse Osmosis)
Reverse osmosis systems and water purifier installations provide high-quality drinking water by removing contaminants at a specific point of use, typically under the kitchen sink. Our team ensures proper installation by:
- Configuring drain connections and storage tanks
- Balancing pressure for consistent output
- Carefully routing connections to avoid interference with the garbage disposal and nearby fixtures
- Integrating the system without disrupting your existing plumbing setup
Water Softener Installation
Hard water can cause scale buildup in pipes, fixtures, and appliances. Water softeners remove minerals that lead to these issues.
Benefits include:
- Reduced buildup in plumbing
- Improved appliance efficiency
- Better water quality for daily use
Sediment and Carbon Filtration Systems
These systems target specific water issues such as chlorine, odor, or visible particles.
They are ideal for:
- Improving taste and smell
- Removing visible debris
- Reducing chemical content in water

Crown Plumbing evaluates:

Frequently Asked Questions
Is San Jose tap water safe to drink?
San Jose’s tap water contains chloramine, which local treatment facilities use for sanitization, but which can affect taste, smell, and skin and eye irritation at higher concentrations. A properly installed filtration system removes these contaminants before the water reaches your tap.
Does San Jose have a hard water problem?
San Jose’s water supply ranks among the hardest in California, with groundwater sources testing between 183 and 440 mg/L of calcium carbonate — well above the 120 mg/L threshold that defines hard water. That mineral content damages water heaters, leaves scale buildup on fixtures, and shortens the lifespan of every appliance in your home that uses water.
Do I need a water test before choosing a filtration system?
Water testing ensures the filtration system matches your specific water quality needs. Our team assesses your home’s water supply before recommending a system — whole-home, under-sink, or point-of-entry — so you get the right solution for your situation.
How often do filters need to be replaced?
Filter replacement depends on the system type and usage, but commonly occurs every six to twelve months. Our team provides maintenance guidance after every installation so your system continues performing at its best.
Can I install a water filtration system myself?
While some water filtration systems may be manageable for homeowners to install independently, many require a certain degree of expertise for accurate installation — including the right tools and knowledge of your existing plumbing setup. Improper installation can affect water pressure, connection integrity, and overall system performance.
