Water Softener Installation in Round Rock & Austin
Round Rock's municipal water averages 14.5 grains per gallon (GPG) — nearly four times the threshold for "hard" water. That means every gallon running through your pipes, appliances, and fixtures carries a heavy load of dissolved calcium and magnesium. Over time, those minerals leave their mark: white scale on fixtures, cloudy dishes, shortened water heater life, and that slight film you can't quite rinse off in the shower.
A whole-home water softener solves all of it at the source. Koala Cooling & Plumbing installs Gemline and Halo water conditioning systems sized for Central Texas homes — with upfront pricing, licensed plumbers, and our 100% Satisfaction Guarantee on every job.
Round Rock Has Some of the Hardest Water in Central Texas
According to the City of Round Rock’s 2024 Consumer Confidence Report, the municipal water supply tests at an average of 14.5 grains per gallon. The EPA considers anything above 3.5 GPG “hard” and anything above 10.5 GPG “very hard.” Round Rock water isn’t just hard — it’s in the top tier.
What that means for your home:
- Water heaters scale up faster, reducing efficiency and shortening lifespan
- Pipes accumulate mineral deposits that gradually restrict flow
- Dishwashers and washing machines work harder and wear out sooner
- Fixtures and glass shower doors develop stubborn white buildup
- Soaps and shampoos don’t lather well, leaving skin feeling dry
If you’re already noticing any of these signs, a properly sized water softener will make an immediate and noticeable difference.
Water Softener Systems We Install
We install two primary product lines — Gemline (traditional salt-based) and Halo (salt-free conditioning) — and we’ll help you choose the right one based on your household size, water usage, and preferences.
Gemline ExStream — Traditional Salt-Based Softener
Gemline ExStream systems are manufactured for Morrison Supply (our distribution partner) and use proven ion exchange technology. Hard water passes through a resin bed where calcium and magnesium ions are swapped out for sodium, delivering genuinely soft water throughout your home.
Gemline benefits:
- Full mineral removal — the classic “soft” water feel in the shower
- Full-flow control valves maintain consistent water pressure
- Sized by grain capacity to match your household’s daily usage
- Lower upfront cost than salt-free systems
- Reliable, field-proven technology
Salt refills: For a typical Round Rock household at 14.5 GPG, plan on refilling the brine tank every 6–8 weeks. We’ll show you how when we complete the installation.
Halo 5 ION — Salt-Free Water Conditioner
The Halo 5 ION uses Template Assisted Crystallization (TAC) to convert dissolved minerals into microscopic crystals that stay suspended in the water rather than sticking to pipes and surfaces. The minerals remain in your water (no ion exchange), but they can’t form scale.
Important: Halo is technically a water conditioner, not a softener. The water won’t feel the same as a salt-based system — but pipes stay clean, appliances run efficiently, and there’s zero salt or maintenance. Many homeowners with concerns about sodium intake or who simply don’t want to manage salt prefer this option.
Halo benefits:
- Zero salt, zero chemicals, zero maintenance
- Whole-home scale prevention
- Available as a combo system with multi-stage filtration (Halo 5 Stage)
- Environmentally friendly — no brine discharge
- Longer system lifespan
⌘ NOTE: We’ll walk you through both options after we test your water and assess your household usage.
Water Softener Pricing — Installed
|
Prices include equipment, installation labor, and connection to your main supply line. We’ll assess your home’s plumbing configuration and confirm the exact price before any work begins. Pricing above assumes the presence of a softener loop and drain. If that doesn't currently exist, more work will be required to install that, and the cost will be higher.
Salt-Based vs. Salt-Free: Which Is Right for You?
Feature | Salt-Based (Gemline) | Salt-Free (Halo 5) |
Removes minerals? | Yes — full ion exchange | No — prevents scale via TAC crystals |
Water “feel” | Silky, classic soft water | Slightly different; scale-free but minerals stay |
Salt required? | Yes — refill every 6–8 weeks | No — maintenance-free |
Best for hard water? | Best for 14+ GPG like Round Rock | Good for moderate-to-hard water |
Adds sodium? | Small amount (typically negligible) | No |
Upfront cost | $3,986 - $4,994 | $6,518 |
Long-term cost | Salt refills ~$10–20/month | Near zero maintenance cost |

How the Installation Works
Scheduling is easy — most installations are completed in a single visit, typically 3–5 hours. Here's what the day looks like:
We start with a quick water test to confirm your hardness level and discuss any other water quality concerns. From there, we size the system to your household's daily usage and give you an exact installed price before any work begins.
Installation happens at your main water supply line, usually in the utility room or garage near your water heater. We shut off the water supply briefly, cut into the water softener loop, and install the softener in-line so every faucet, fixture, and appliance in the home gets treated water. For salt-based systems, we also connect the brine tank and attach to the drain line. The whole footprint is compact — roughly the size of a tall water heater.
Once it's plumbed in, we configure the regeneration cycle for Round Rock's 14.5 GPG hardness level, run the system through its first cycle, and test the output water before we leave. We'll show you how to monitor the salt level, what a normal regeneration sounds like, and how to reach us if anything comes up.
You'll notice the difference the first time you shower.
We're licensed plumbers — not contractors who sub out the work. The same team that quotes the job installs it.
What Our Customers Say About Us
Faq
The most common signs: white scale buildup on faucets or in your shower, cloudy dishes coming out of the dishwasher, dry skin or hair after showering, reduced lather from soap or shampoo, and spotty residue on glass. If you’re on Round Rock city water, you almost certainly have water hard enough to benefit from softening.
Most residential water softener installations take 3–5 hours. We connect to your main water supply line, configure the system settings for your water hardness level, and verify everything is cycling correctly before we leave.
A water softener (like our Gemline systems) actually removes calcium and magnesium through ion exchange, delivering water that feels noticeably “soft.” A water conditioner (like the Halo 5 ION) keeps the minerals in the water but changes their structure so they can’t form scale. Both protect your pipes and appliances. We’ll walk you through both after testing your water.
For an average Round Rock household at 14.5 GPG, plan on refilling salt every 6–8 weeks. Higher water usage means more frequent regeneration cycles. We’ll show you how to check the brine tank and what to look for when we complete the installation.
No — a properly sized and installed system should have no noticeable effect on water pressure. Gemline and Halo systems both use full-flow control valves designed to maintain consistent pressure throughout the home. If your pressure is already low, we’ll flag that during the assessment.
Yes — call us at (512) 759-8800 and we’ll assess your existing system. Whether it needs a repair, a settings adjustment, a resin replacement, or you’re ready to upgrade, our licensed plumbers can help.
