What Does Reverse Osmosis Installation Include in Round Rock, TX?
Reverse osmosis installation covers five topics: how RO systems work, under sink installation, whole house systems, membrane replacement and pairing RO with a water softener.
How Reverse Osmosis Systems Work
Reverse osmosis (RO) pushes water under pressure through a semi-permeable membrane that rejects dissolved solids. Clean water passes through to a storage tank and a dedicated faucet, and the rejected water goes to the drain. A typical under-sink system has four stages: a sediment filter, a carbon filter, the RO membrane and a final polishing filter. RO reduces a wide range of dissolved substances, including salts, many metals and fluoride.
Under Sink RO Installation
An under-sink RO system treats the water for one tap, usually the kitchen. It installs in the cabinet, adds a small faucet and a storage tank and connects to the drain. It is the most common home RO setup and gives high-quality drinking and cooking water without treating the whole house.
Whole House RO Systems
A whole house RO system treats all the water entering the home. It needs a larger membrane array, a storage tank and a booster pump, and it sends more water to the drain. It suits homes with a serious dissolved-solids problem. Most homes get better value from a softener for the whole house and RO at the kitchen tap.
RO Membrane Replacement
The membrane wears out as it loads with minerals. Membranes commonly last two to three years, depending on water quality and use, and sediment and carbon filters need changing more often. As a typical schedule, replace pre-filter cartridges every 6 to 12 months and the membrane every 2 to 3 years. We replace the membrane, change the filters and sanitize the system.
RO and Water Softener Combination
Hard water scales an RO membrane and shortens its life. A water softener ahead of RO protects the membrane. Round Rock’s supply is surface water from Lake Georgetown and Lake Travis plus Edwards Aquifer groundwater, so the pairing makes sense for many local homes. The City’s 2025 water quality report put average hardness at 249 mg/L, about 14.6 grains per gallon, which the U.S. Geological Survey rates as very hard.
Reverse Osmosis Cost in Round Rock
Cost depends on system size, number of stages, storage capacity and installation work. Ongoing cost includes filter and membrane replacement. Our estimate is free and itemized.
Not a good fit if… you want mineral-rich water, since RO removes beneficial minerals along with the rest, or you cannot spare space under the sink.
Is reverse osmosis right for your water?
RO is right when you want the cleanest drinking water or need to reduce a specific dissolved contaminant. A water test and a short conversation tell you whether a simpler filter will do.

Frequently Asked Questions
Does reverse osmosis remove hard water minerals?
Yes, RO removes most dissolved minerals from the water it treats, but hard water scales the membrane, so pairing RO with a softener is best.
How much water does an RO system waste?
RO sends reject water to the drain. The ratio depends on the system and water pressure. Most traditional systems send about 3 to 4 gallons of water to the drain for every gallon of purified water, while high-efficiency models get closer to 2 to 1.
How often do I change RO filters?
Sediment and carbon filters usually change every six to twelve months, and the membrane every two to five years. Follow your system’s guidance.
Does RO make water taste different?
Yes. RO water tastes cleaner and flatter because minerals are removed.
Can you install RO in my kitchen?
Yes, under-sink installation is our most common RO job.
