Water touches every aspect of your daily life — from the coffee you drink in the morning to the shower you take before bed. At JustUs Plumbing, we believe your family deserves water that’s clean, safe, and tastes great at every faucet. Unfortunately, in many Round Rock, TX homes, water from the tap can contain sediment, chlorine, heavy metals, and other impurities that affect health, comfort, and plumbing performance.
That’s where a whole house filter comes in. Installed directly at your main water line, it ensures every drop of water that flows into your home is filtered and ready for safe use — whether you’re cooking, showering, or doing laundry.
What Is a Whole House Filter?
A whole house water filter is a point-of-entry filtration system that cleans all the water entering your home. Unlike under-sink or countertop units that filter only one location, a whole house system treats every water source — sinks, showers, washing machines, and outdoor spigots. This ensures your family enjoys cleaner, better-tasting water throughout your home.
Why Homeowners in Round Rock, TX Need Whole House Filters
Even if your water comes from the city supply, it may still carry contaminants. Municipal water treatment removes harmful bacteria, but chlorine, sediment, and dissolved minerals often remain. These can cause:
- Scale buildup in pipes and appliances.
- Unpleasant odors or metallic tastes.
- Irritated skin and brittle hair after showering.
- Staining on fixtures, dishes, or clothing.
- Reduced appliance efficiency and lifespan.
For homes on private wells, additional concerns include bacteria, iron, manganese, and agricultural runoff. A professionally installed whole home water filtration system offers peace of mind and a healthier living environment.
Key Benefits of a Whole House Water Filtration System
When you choose JustUs Plumbing for whole house filter installation, you’re investing in more than just water quality. You’re protecting your home, your health, and your plumbing system.
1. Healthy, Great-Tasting Water Everywhere
Whether you’re filling a glass at the kitchen sink or rinsing vegetables, you’ll enjoy water free from unpleasant tastes and odors.
2. Protection for Plumbing & Appliances
Hard minerals and sediment can clog pipes and damage water heaters, dishwashers, and washing machines. Filtration reduces wear and tear.
3. Cleaner Showers & Softer Skin
Removing chlorine and other harsh chemicals helps improve skin hydration and hair texture.
4. Longer Appliance Lifespan
Filtered water reduces scale buildup in appliances, meaning fewer repairs and replacements.
5. Consistent Filtration for the Whole Home
Unlike single-point systems, every tap benefits from the same water quality.

People Also Ask: Your Questions, Answered
How long do whole house water filters last?
Most filter cartridges last 6–12 months, but high-capacity or specialty systems may last up to 5 years. Lifespan depends on water usage and local water quality.
Is a whole house water filter worth it?
Yes. It protects your family’s health, safeguards plumbing, extends appliance life, and improves taste and odor — often saving money over time on repairs and bottled water.
Where should a whole house water filter be installed?
Typically, it’s placed near your home’s main water shut-off valve so that all water entering your home passes through the filter before reaching fixtures.

Standard filters do not remove hardness. For hard water, we recommend a water softener and whole house filter combination.

Regular maintenance includes replacing filter cartridges on schedule and having your system inspected annually by a licensed plumber.

Can I install a whole house water filter myself?
