Cibolo’s hard water and attic or garage installs are tough on water heaters. If your water heater is running out of hot water, making popping sounds, or dripping into a pan, Radiant’s licensed plumbers know exactly where to look. In newer two-story homes, heaters often sit in hot attics with long runs to upstairs baths, so scale builds fast, thermostats overwork, and dip tubes or anode rods wear out early. We start with smart basics; we check inlet temperature and water pressure, test safety controls, inspect the expansion tank, and flush sediment to restore capacity. For tankless units, we perform a full descaling and verify gas volume, venting, and condensate routing so you get steady hot water at every tap.
Local details matter, too. Neighborhoods off FM 1103 and near Cibolo Creek see soil movement that stresses supply lines – we check connections and flex lines for hidden leaks. Winter cold snaps can freeze garage lines or attic lifts, so we insulate exposed piping, confirm pan drains and T&P discharge, and add leak alarms where they make sense. If repair won’t outlast the wear, we’ll size a right-fit replacement for your family’s use, discuss efficiency options, and install clean, code-compliant systems with labeled shutoffs and neat, serviceable piping. You’ll get clear choices and up-front pricing before any work begins.
We’re San Antonio-proud and Cibolo-focused. If your tank or tankless water heater needs repair—or, you’re ready for a reliable upgrade—Radiant answers the call with transparent pricing and workmanship that lasts.
