"Exemplary Service and Impeccable Results: A Stellar Experience with Clear Water Source I recently had the pleasure of working with Clear Water Source,, for the installation of a water softener system and reverse osmosis in my home, and I am thrilled to say that my experience was nothing short of exceptional. From start to finish, Clear Water Source demonstrated their professionalism, punctuality, and commitment to delivering an outstanding final product. Right from the initial consultation, Mark and his team at Clear Water Source impressed me with their knowledge and expertise. They took the time to understand my specific needs and concerns, patiently addressing all my questions and offering valuable insights into the benefits of a water softener system. Their level of professionalism and dedication to customer satisfaction was evident from the very beginning. On the day of installation, Pedro, the skilled installer from Clear Water Source, arrived right on time, ready to get to work. Pedro was polite, courteous, and respectful of my home, ensuring minimal disruption during the entire process. He was well-prepared and equipped with all the necessary tools and materials, displaying a high level of efficiency and expertise. The installation process itself was carried out with meticulous attention to detail. Pedro worked diligently, ensuring that every component was properly installed and that the system was functioning optimally. He went above and beyond to address any challenges that arose during the installation, displaying his problem-solving skills and commitment to delivering a flawless final product. Once the installation was complete, Mark and Pedro took the time to explain the system's operation, its maintenance requirements, and provided me with useful tips to maximize its efficiency. Their dedication to customer satisfaction was evident throughout the entire process, and I felt confident that I was in capable hands. The end result was truly remarkable. The water softener system installed by Clear Water Source has made a significant difference in the quality of water in my home. I noticed an immediate improvement in the taste and texture of the water, and the reduction in mineral buildup on fixtures and appliances has been remarkable. I am incredibly satisfied with the final product and the overall performance of the system. In conclusion, I cannot recommend Clear Water Source, led by Mark and installer Pedro, highly enough. Their professionalism, punctuality, and dedication to providing an excellent customer experience are truly commendable. If you are looking for a water softener company that goes above and beyond to deliver outstanding results, Clear Water Source is the clear choice. I would highly recommend them and I would not hesitate to work with them again in the future. Thank you, Clear Water Source, Mark, and Pedro, for your exemplary work and for transforming the water quality in my home."

"I had another plumber come out and said he'd need to remove the entire bathtub and refused to look at it further. Andre came out and knew exactly what to do; he was courteous, punctual and most of all he got me going for an extremely reasonable price in about an hour. I've been draining my tub with a bucket for three weeks; now I can finally take a shower again (I guess you can say this was on my bucket list!). I can't praise Andre and Quality Plumbing highly enough! He's got a big thumbs up from me :-)!"

FAQs for water treatment & purification system installation and replacement projects in San Jose, CA
A whole-house water filtration system is ideal if you want all the water in your home to be filtered, improving water quality and protecting your plumbing. This system can enhance your home's value. If you only need filtered water for drinking or cooking, a point-of-use filter might be a suitable alternative. Each filtration option is designed to remove specific contaminants.
Maintaining your whole‑house water filtration system is essential for uninterrupted performance and clean water. The annual expense, which ranges between $50 and $300, covers filter replacements, complete system inspections, and any required repair work. Regular maintenance keeps the system operating at peak efficiency and guarantees the highest water quality for every home use.
Installing a whole‑house water filtration system is a streamlined process that a professional can complete in one day. Multistage systems require additional time to secure proper plumbing connections and calibrate the system accurately. In contrast, point‑of‑use filters are installed within a few hours, ensuring efficient and precise integration in your home.
Most whole-house filtration systems last 10 to 20 years with proper care. Reverse osmosis units typically serve 10 to 15 years, while water distillers can exceed two decades. Lifespan depends on build quality, water chemistry, and whether filters, lamps, or membranes are changed on schedule. Regular professional inspections help you catch minor issues before they shorten the system’s life. Budget for planned component replacements to reach the upper end of that range.
Fast clogging usually points to high sediment levels, heavy water use, or both. When more dirt and minerals flow through the system, filters load up sooner and performance drops. Schedule a water test to confirm what’s in your supply, add a sediment pre-filter if needed, and follow the manufacturer’s replacement timeline to keep water pressure and quality where they belong.
