Clean Water From Your Kitchen Faucet

Professional reverse osmosis system installation for homeowners in Marble Falls, Texas.

When you fill a glass of water in your Marble Falls home, you want it to taste clean and look clear without any odd smell lingering after each sip. A reverse osmosis system gives you that result by filtering your tap water through a multi-stage process right under your kitchen sink, removing the dissolved solids and contaminants that affect flavor and odor before the water reaches your glass.


Marble Falls Plumbing LLC installs point-of-use reverse osmosis systems designed to fit beneath a standard kitchen sink without taking up excessive cabinet space. The system connects directly to your cold water line and includes a dedicated faucet installed on your countertop or sink deck. Water passes through several filter stages and a semi-permeable membrane that separates contaminants from the purified water, which is then stored in a small pressurized tank until you open the dedicated faucet. The filtered wastewater drains into your sink's drain line as part of the normal operation.

What Happens During the Installation

Your installation begins with a full assessment of the cold water supply line under your sink and the available cabinet space for the storage tank and filter housing. We shut off the water supply, cut into the cold line with a saddle valve or compression fitting, and run a dedicated feed line to the reverse osmosis unit. The system is mounted securely to the inside wall of the cabinet, and we drill a hole through your sink deck or countertop to install the filtered water faucet if one is not already present.


Once the system is connected and pressurized, you will notice that the water from the dedicated faucet tastes noticeably cleaner, has no chlorine smell, and appears clearer than what comes from your regular tap. The system reduces common contaminants including dissolved minerals, chlorine byproducts, and sediment that affect taste and clarity.


We connect the drain line from the system to your sink's drain pipe using an air gap or direct fitting depending on local code requirements in Marble Falls. The system needs periodic filter replacements, typically every six to twelve months depending on your water usage and source water quality. The membrane itself may last two to three years before replacement is needed. We do not include ongoing filter changes in the installation, but we can walk you through the replacement process or schedule maintenance visits.

Questions You Might Have About This System

Homeowners often want to know how the system will fit into their daily routine and what kind of maintenance they should expect after installation.


  • What contaminants does reverse osmosis remove? The system reduces dissolved solids such as calcium, magnesium, sodium, chlorine, fluoride, lead, and arsenic, along with sediment and particles that affect taste and clarity. It does not remove all bacteria or viruses unless paired with an additional UV filter.
  • How much water does the system waste? For every gallon of purified water produced, the system sends roughly three to four gallons of reject water down the drain. This is normal operation and ensures the membrane stays clean and functional.
  • How long does installation take? Most installations in Marble Falls take two to three hours depending on the complexity of your plumbing layout and whether we need to drill a new faucet hole. We complete all connections, test the system, and flush the filters before finishing.
  • What happens if I run out of filtered water? The storage tank holds between two and four gallons of purified water depending on the model. If you empty the tank, you will need to wait about an hour for it to refill as the system produces water slowly. The flow rate from the faucet will drop noticeably when the tank is low.
  • When should I replace the filters? Pre-filters and post-filters typically need replacement every six to twelve months based on your household water usage and source water quality. The reverse osmosis membrane usually lasts two to three years before performance declines and replacement is needed.
