Your water vs the tankless line

Right at the line tankless warranties draw.

Rheem, Navien and Noritz don’t cover scale damage to tankless water heaters when water is harder than 200 mg/L, about 11.7 grains per gallon. Most city water here sits just under that line, and Round Rock’s is over it. Private wells run about twice as hard.

These are published figures. Your own tap can differ, which is why we test it.

Water hardness by town, with sources
Lampasas County wells (median)

Burnet County wells (median)
21.6
Llano County wells (median)
19.2
Williamson County wells (median)

Four systems. Published prices.

Filtration that fits your water.

The test decides which you need. Many homes need only one; wells often need a sediment filter ahead of the softener.

Priced at your water test

Upkeep: A new cartridge every 3–6 months.

Your technician sizes the system from your test and gives you a written, flat-rate price before any work starts. Prices assume your home already has a softener loop. If it doesn’t, installing one needs a custom quote.

How we size a softener

Sized to your water, not the biggest tank.

  1. 1

    Your hardness

    We measure it at your tap. Iron counts too: each part per million adds about four grains to what the softener has to remove.

  2. 2

    Your household

    We count people and bathrooms. More people means more hardness removed each day, and more bathrooms means more water at once.

  3. 3

    An efficient salt setting

    We choose the resin volume and salt dose for salt efficiency, not maximum capacity. Most homes here need 1 to 2 cubic feet.

High iron, a sulfur smell or manganese needs an iron filter, which we quote separately.

Why we install Clack valves

Every softener we install runs on a Clack WS1 metered valve, so it regenerates based on the water you actually use, not a timer.

Clack valves aren’t proprietary. Parts come from any water treatment supplier and any qualified technician can service them, so you’re never tied to us. Some brands use valves only their own dealer can service.

And if you already have a softener, we service every brand.

What the test checks

From booking to your results.

01

Book your free test

Pick a time online or give us a call. About 30 minutes, no obligation.

02

We test at your tap

Hardness, pH, Alkalinity, Total dissolved solids (TDS), Iron and Manganese. We also note water pressure, clarity and any staining.

03

You choose

We explain the results, recommend a system if you need one and give you a written price. Nothing is installed unless you approve it.

It’s a screening test for what treatment fixes, not a lab safety test. Hardness isn’t a health concern. If you’re on a well and want a bacteria or nitrate test, use a certified lab, and we’ll point you to one.

Upkeep

Know the care your system needs.

Every system needs a little attention. Brandenburg One members can hand it to us for a monthly add-on.

Softener

Salt every one to three months, and a yearly service.

Softener Brine Tank Service$10/month

Reverse osmosis

Filters every 6–12 months, membrane every 2–3 years.

Good questions, clear answers

Before your water test.

Have a question about your water or your current system? Call us at (512) 756-9847.

Is the water test really free?

Yes. There’s no charge and no obligation. Your technician tests the water at your tap, explains the results, and if you want a system, sizes it and gives you a written price before any work starts.

Is the test a safety test?

No. It’s a screening test for what treatment fixes: hardness, pH, alkalinity, dissolved solids, iron and manganese. It can’t tell you whether your water is safe to drink. If you’re on a well and want a bacteria or nitrate test, use a certified lab, and we’ll point you to one.

What does the monthly softener payment cover?

The installed softener at its flat-rate price, the same whether you pay up front or finance it, split into 24 monthly payments at 0% APR with $0 down, subject to credit approval. Prices assume your home already has a softener loop. If it doesn’t, installing one needs a custom quote.

Can someone else service my softener later?

Yes. We install Clack valves, which aren’t proprietary: parts come from any water treatment supplier, and any qualified technician can service them. We also service every brand.

What are the signs I have hard water?

Common signs include white or chalky buildup on faucets and showerheads, spots on dishes and glassware, soap that doesn't lather well, dry or itchy skin after showering, dull or stiff laundry, and reduced water pressure. You may also notice your water heater and appliances failing prematurely due to scale buildup.

What's the difference between a water softener and a water filter?

Water softeners remove hardness minerals (calcium and magnesium) to prevent scale buildup and improve water feel. Water filters remove contaminants like chlorine, sediment, bacteria, and chemicals to improve taste, odor, and safety. Many homes benefit from both systems working together—a softener for the whole house and additional filtration for drinking water.

Do I need a whole-house filter or just a drinking water filter?

It depends on your water quality and concerns. If your municipal water has chlorine taste/odor or you have sediment issues, a whole-house filter improves water throughout your home for bathing and laundry. For drinking water safety and taste, an under-sink reverse osmosis (RO) system provides the highest level of filtration. We can test your water and recommend the right solution.

Will a water softener make my water taste salty?

No. While water softeners use salt for regeneration, the amount of sodium added to softened water is minimal and typically unnoticeable. If you're on a strict low-sodium diet, you can install a reverse osmosis system at your kitchen sink for drinking and cooking water, or opt for a potassium-based softener instead of sodium.
