Water Softeners

Hard water contains dissolved minerals that form deposits inside your heaters, washers, and other water-using appliances. These make them work harder than necessary.

Marin H2O installs water softeners that condition your water and deliver soft water throughout your home. They offer a Portable Exchange Service water softener, considered a smart, environmentally conscious way to enjoy the benefits of soft water.

Home Filters

If your water system does not have a filter, you are a filter. Let Marin H2O install a reverse osmosis home filtration system to provide you with delicious, pure drinking water. The system reduces contaminants as small as an atom. They offer environmentally preferred water filtration systems with recyclable components, reducing landfill waste and saving resources.

Drinking Water Systems

Culligan bottle-less cooler systems offer the latest advantages in technology to treat your existing water supply and provide your home or office with an endless supply of hot and cold drinking water.

Whether your system utilizes advanced carbon filtration or state-of-the-art reverse osmosis, Culligan can provide the highest quality water at the touch of a button. These systems refill automatically, so you don’t need to keep a supply of bottles on hand.

De-ionized Water

Ions from minerals such as sodium, calcium, iron, copper, chloride, or bromide are present in most tap water. De-ionization is a physical process that uses specially-manufactured ion exchange resins to bind to, filter out, and remove mineral salts from the water. Because the majority of water impurities are dissolved salts, de-ionization produces a high purity water. Our portable exchange tank provides service for high purity water applications such as spot-free rinsing for commercial service companies that wash boats and planes.

Marin H2O Plumber with sewer video equipment Waste Line/ Drain Line Management:

We can’t crawl into your pipes, but the next best thing is to survey your system using a video camera. A color camera inserted into the pipeline becomes our eyes, finding damaged or blocked sections that need to be cleared, replaced or repaired. In case of blockage, we offer full rooter service to cut away any aggressive tree roots that have invaded your sewer lines.
