"Dallas and Jesus were knowledgeable and professional. They did the work quickly yet thoroughly and were sure to clean up afterwards. The cost was competitive with other plumbing busineses without being overpriced. For my toilet installation, they charged slightly more than Home Depot, the difference being that Home Depot could not provide same day service nor take the time to answer all of my questions (Coast Mechanical did those and more) I will call Coast Mechanical for my future plumbing needs."

"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."

Water treatment & purification system installations and replacements FAQs

In a reverse osmosis system, water from your main line—or from a designated faucet—is pushed through a semipermeable membrane under pressure. The membrane’s microscopic pores trap dissolved solids, heavy metals, and other contaminants, while clean water passes into a storage tank or straight to the tap. The leftover concentrated water simply drains away. The result is clear, great‑tasting water delivered right where you need it.

A plumber can set up a point‑of‑use unit in one to two hours. A whole‑house system is more involved and often takes one to two days because it ties into the main supply line and may need extra plumbing. During installation, the pro mounts the unit, connects the pipes, checks for leaks, and tests performance so you’re ready to pour a glass as soon as they leave.

Reverse osmosis removes dissolved solids, heavy metals, and many microorganisms, giving you water that tastes cleaner and protects your family. Softer water also helps appliances, faucets, and ice makers last longer. Because you’re filling reusable bottles instead of buying single‑use plastic, most homeowners save money and cut waste. In short, you get better‑tasting water, longer‑lasting appliances, and a smaller environmental footprint from one straightforward system.
