Real Problems. Scientific Solutions.

Full 3-day PEX-A expansion repipe. Acoustic pipe mapping identified 14 hidden branch points without opening plaster walls unnecessarily. All historical fixtures retained original positions. Post-repipe water lead testing was 100% clear on day 4.

Ultrasonic acoustic leak detection and infrared thermal imaging pinpointed the concrete fracture location to within 6 inches. Targeted concrete core drilling (14" diameter) enabled a trenchless epoxy repair without closing business operations.

Emergency dispatch arrived in 18 minutes. The technician applied a cryogenic liquid CO2 pipe-freeze kit to isolate the active burst line without city water shutoff. Replaced the 6ft compromised copper segment with freeze-tolerant PEX tubing by 5:30 AM.

Cured-In-Place Pipe (CIPP) epoxy relining. High-pressure hydro-jetting cleared root masses, continuous HD video verified line geometry, and an 8-inch resin-impregnated felt liner was inverted and UV-cured in 4 hours with zero surface disruption.

Engineered and installed a cascade array of 2× Navien condensing tankless units with a dedicated return recirculation loop. Units modulate dynamically between 19,900 and 199,900 BTU to meet peak dishwasher demand without standby standby loss.

Full safety audit per NFPA 54 / ANSI Z223.1. Replaced all substandard CSST connections with heavy Schedule 40 black iron pipe. Installed code-compliant equipotential ground bonding per NFPA 70 and completed a 1.5× working pressure test holding 10 PSI for 60 minutes.
