"Custom H2O does a significant amount of large commercial projects and rely mostly on word of mouth. Many of their clients include hospitals, so the equipment they sell is very high performance. I spoke with the president, Chris over the phone about initial details on what I am looking for in a water softener. After that, Chris made a point to schedule a visit to see the house and plumbing before proceeding. He looked over the overall layout, checked the water pressure, and took detailed measurements before advising us on our installation options and products. The discussion focused on key concepts like different substances carbon and resin filter out, not about sales gimmicks or overselling. After the initial quote, Chris actually called to hold off the installation for a week to take advantage of an upcoming manufacturer rebate. Their knowledge, experience, and integrity speak volumes."

"I need to share my experience with Clear All Rooter. I called them a few weeks ago to replace my 14 yr old water heater. I told them I wanted to use a water heater by Bradford and White. He quoted my $2800.00 for a 50 gallon water. I did not do my due diligence and just said go ahead and replace it. I was kind of stressed at the time. Only later did I realize that the heater cost $1020.00 and I ended up paying $1800.00 for installation which I consider a massive rip off. It is all my fault for not asking upfront about product cost and labor. Dont make the same mistake. I ended up making a home improvement loan to pay it off over the next two years. They did a great job of installation but I dont think it was worth $1800.00. I am a veteran who lives a modest lifestyle and I dont appreciate this type of treatment. Please beware when you use Clear All Rooter. This could happen to you."

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.
