Drinking water & RO · Buda, Kyle & San Marcos
Drinking water worth filling a glass with
A reverse osmosis system filters your drinking water through a membrane fine enough to remove most dissolved solids, then serves it chilled-pitcher clean from its own faucet at the sink. It treats the water you drink and cook with, where taste matters most.
Why does tap water taste off here?
Limestone water carries a heavy load of dissolved minerals, and the disinfectant that keeps it safe adds its own note on top. Neither is a safety problem. Together they're why so many local kitchens run on bottled water and fridge pitchers.
Buying your drinking water back one case at a time gets old, and it costs more per year than most people guess. Treating the one tap you drink from is the direct fix.
How it works
How does reverse osmosis work?
Three stages fit under one sink. The water you pour took this path.
Carbon protects the membrane
A carbon pre-filter takes out chlorine and grit first, because chlorine shortens a membrane's life. It's cheap insurance for the expensive part.
The membrane does the real work
Water is pushed through a membrane with pores fine enough to reject most dissolved solids: the minerals, salts, and metals that flavor tap water. What's rejected rinses down the drain.
Stored and served at its own faucet
Clean water waits in a small tank under the sink and pours from a dedicated faucet, so drinking and cooking water is always ready without running the system on demand.

What changes
What RO changes in your kitchen
It's a small system that makes a big difference in the kitchen.
Water you drink because you want to
The most common thing we hear after an RO install is that the family just drinks more water. It's right there and it tastes clean.
The bottled water run ends
You stop hauling, storing, and recycling flats of bottles. The per-gallon cost of RO water is a small fraction of bottled.
Cooking tastes cleaner
Rice, beans, stock, and anything that simmers absorbs the water it cooks in. Starting clean is a real, tasteable difference.
Clear ice, clean fridge water
Add the fridge line and the ice maker feeds from the same system, so ice stops carrying the tap's minerals and off-tastes.
Straight talk
Yes, RO sends water down the drain
Every RO system rinses its rejected minerals away with some water. That's not a defect. It's how the membrane stays clean, and you should know it before you buy. Modern systems reject far less than the old ones, and for drinking and cooking volumes the difference on a water bill is small.
We'll tell you the actual ratio of the system we recommend and what it means in gallons for your household.
Questions
Questions we get about RO
Is reverse osmosis water safe to drink long-term?
Yes. RO water is simply water with most of the dissolved solids removed. You get the minerals your body uses from food, not meaningfully from tap water. If you prefer a mineral taste, a remineralization stage adds a measured amount back, and we can include one.
Does RO waste water?
Yes, it sends some water down the drain. That's how the rejected minerals leave. Older systems drained several gallons per clean gallon. Current systems are considerably better. For a family's drinking and cooking water, the drain-side volume is small next to everyday uses like laundry or lawn watering. We'll show you the ratio for the system we quote, honestly.
Why not filter the whole house with RO?
Because you'd be paying to purify shower and lawn water, and RO's slow, storage-based flow isn't built for that. The right pattern for most homes is RO at the kitchen for what you drink, and a softener or carbon filtration for everything else.
How often does it need service?
Pre- and post-filters typically change once a year, and the membrane runs for several years when the pre-filters are kept up. We service what we install and track the schedule for you.
Will it fit under my sink?
Almost always. The tank and filter set are sized for a standard cabinet, and we'll confirm fit during the consultation, including the fridge line if you want ice and fridge water on the system.
Do I need RO if I already have a softener?
They do different jobs. A softener fixes hardness house-wide, but it doesn't remove the dissolved solids that affect taste at the glass. Plenty of homes run both, with soft water everywhere and RO at the sink. The free test shows whether your drinking water would actually benefit.
Taste is measurable. Let's measure it.
The free test includes total dissolved solids at your kitchen tap, the number behind most taste complaints. A 30-minute test gives you the information to make an informed decision about your drinking water.
