Reverse Osmosis Systems for Austin and the Highland Lakes & Hill Country

A reverse osmosis (RO) system gives you cleaner, better-tasting drinking water by forcing it through a fine membrane that removes contaminants other filters leave behind. Lantz Home Services installs and services both under-sink (point-of-use) and whole-home RO systems for homeowners across the Highland Lakes, the Hill Country, and the greater Austin metro. Our licensed plumbers size the system to your water, install it right the first time, and stand behind the work.

Why Local Water Makes RO Worth It Here

Water on this side of Central Texas is hard, and a lot of it comes from private wells, lake-fed supplies, and small rural systems rather than a single big-city utility. Homes pulling from the Highland Lakes chain, Lake LBJ, Lake Marble Falls, Lake Travis, Lake Buchanan, and well water around Spicewood, Horseshoe Bay, and Granite Shoals routinely deal with high mineral content, sediment, and taste and odor issues that a basic pitcher filter never touches. We have spent 50-plus years working on water in exactly these communities, so we size and place RO systems around the realities of local water instead of a generic spec sheet.

A reverse osmosis system is the most effective point-of-use option for drinking and cooking water because it reduces dissolved solids down to the microscopic level, the minerals, salts, and contaminants that survive a standard whole-home filter or softener.

What a Reverse Osmosis System Removes

RO systems use a multi-stage process to reduce a wide range of contaminants commonly found in Central Texas water:

• Dissolved solids (TDS) — the mineral load behind that flat or metallic taste
• Sediment and rust from older lines and well systems
• Chlorine and chloramine taste and odor
• Arsenic and fluoride
• PFAS ("forever chemicals")
• Microplastics
• Herbicides and pesticides — relevant for rural and well-fed properties
• Heavy metals such as lead
• Many other dissolved contaminants

A typical residential RO system runs water through at least three stages: a prefilter that strips sediment and chlorine before they can damage the membrane, the RO membrane itself that removes dissolved solids, and a postfilter that polishes the water on its way to a dedicated faucet.

Why Homeowners in the Highland Lakes Choose RO

• Cleaner drinking and cooking water. RO removes the dissolved contaminants that softeners and whole-home filters are not built to catch.
• Better taste, every glass. No more buying bottled water by the case, your tap becomes the source.
• Protection for fixtures and appliances. Cleaner water means less buildup affecting faucets, ice makers, and connected appliances.
• Right-sized for your home. We match point-of-use vs. whole-home RO to how your household actually uses water.

Reverse Osmosis Installation Done Right

Installing an RO system is more than connecting a couple of lines under the sink. It takes correct placement, secure and sealed fittings, and proper attention to drainage and water pressure so the system performs for years. A bad DIY or handyman install is one of the most common reasons we get called out, leaks inside the cabinet, low flow at the faucet, or a membrane that fails early.

Our licensed plumbers handle every detail, from sizing and placement through final testing, and we often complete installs same day. Whether you are adding a new under-sink drinking water system or upgrading an aging setup, we make sure it is leak-free and dialed in before we leave.

Service, Support, and Filter Maintenance

RO systems need routine care to keep working well, mainly filter and membrane replacements on a schedule set by your water quality and usage. Hard, mineral-heavy Highland Lakes water tends to load filters faster, so the right interval here is often shorter than a manufacturer's generic estimate. We handle filter changes, membrane swaps, and annual check-ups for whole-home systems, and we can build RO maintenance into a regular service plan so you never have to track it yourself.
