If your shower runs cold after the first person, your tank rumbles, or the tap never quite gets hot, chances are, you’re feeling the reality of Round Rock’s hard water. Mineral buildup inside your equipment can steal heat and shorten the life of your water heater, especially in two-story homes with long pipe runs to upstairs baths. Add our quick winter cold snaps and you get surprises at the worst times, like before a game at Dell Diamond or after a long afternoon at Old Settlers Park. Radiant keeps it simple; we arrive on time, explain everything in plain language, and give you clear pricing before any work begins.
On a typical visit, we clear out sediment that’s slowing your hot water, replace worn parts that cause temperature ups and downs, track down small leaks before they spread, and set the temperature for comfort and safety. For tankless models, we handle error messages, remove mineral buildup, and make sure multiple taps can run at once without going lukewarm. If your water heater is nearing the end, we’ll lay out straightforward repair vs. replace options and show you how to protect a new system from Round Rock’s hard water for optimal longevity, such as routine flushing and water treatment solutions sized for your home and use.
