PROTECTION, PLANT & SERVICE CAPABILITIES

Backflow Prevention

Reduced-pressure, double-check and air-gap assemblies, test cocks, enclosures and freeze protection, with testing performed by DPOR-certified backflow workers as Virginia requires.

Water Heaters & Boilers

Commercial storage and tankless water heaters, condensing and non-condensing boilers, hydronic specialties and venting, with ASME / National Board documentation where applicable.

Service & Maintenance

Replacement parts, repair components and planned-maintenance material support for commercial plumbing and hydronic equipment.

Retrofit & Replacement

Like-for-like and efficiency-upgrade equipment replacements staged for short outage windows, with isolation, drain-down and tie-in components.

WHAT WE SUPPORT IN PROTECTION, PLANT & SERVICE

Cross-connection control: assembly selection by hazard level, installation clearances, test-port access and annual-test documentation.
Commercial water heating: storage, tankless and heat-pump water heaters, recirculation, mixing valves and thermal-expansion tanks.
Boilers & hydronic plants: heating boilers, pumps, expansion tanks, air and dirt separators, glycol feed and combustion-air / venting components.
Legionella & water quality: water-management program support, flushing and disinfection components, and temperature and chemical monitoring points.
Pressure-vessel compliance: ASME-constructed, National Board-stamped equipment registered and inspected under Virginia DOLI rules.
Planned maintenance: filters, anodes, relief valves, gaskets and wear items stocked or staged for scheduled outages.
Emergency response material: pipe, couplings, repair clamps and valves available from Newport News warehouse inventory when in stock.
Efficiency retrofits: low-flow fixture replacements, recirculation controls and condensing-boiler upgrades.

REGULATORY NOTES

Backflow testing (Virginia):must be performed by a DPOR-certified Backflow Prevention Device Worker at installation, annually and after repair or relocation.
Boilers & pressure vessels:Virginia requires ASME-constructed, National Board-stamped, DOLI-registered equipment; heating boilers generally inspected biennially, power boilers annually.
Gas piping:natural-gas and LP piping is a separate Virginia specialty (GFC) from plumbing (PLB).
Lead-free:potable water products must meet the SDWA ≤ 0.25% weighted-average lead definition.
