U.s. Naval Plumbing LLC

U.s. Naval Plumbing LLC, doing business as US Naval Plumbing LLC, is a woman-owned small business manufacturer of maritime plumbing components and fixtures based in Virginia Beach, Virginia, competing predominantly as a prime contractor on full-and-open Defense Logistics Agency purchase orders and delivery orders.

The vendor manufactures and supplies concrete maritime plumbing goods: elbow pipes, elbow hoses, tube reducers, water closet bowls and seats, faucets and faucet stems, shower heads, drain assemblies, traps, flush connection units, valves, coupling pipes, and related sanitary fixtures for naval vessels and military facility maintenance. Recent representative prime awards include a $203.4 million purchase order to US Pacific Fleet Forces for plumbing parts (April 2025), a $196.96 million order to DLA Troop Support for 160 water closet units (July 2025), a $100.6 million delivery order to DLA Land and Maritime for elbow pipes (June 2022), and two Naval Sea Systems Command total small business set-aside orders for shipboard piping and related material on USS New York (LPD-21) for $20.6 million (July 2025) and USS San Antonio (LPD-17) for $27.6 million (February 2026).

Customer concentration is extreme. The top two customers—Defense Logistics Agency Land and Maritime and Defense Logistics Agency Troop Support Construction and Equipment—account for approximately 95% of recent awards and approximately $4.5 million combined potential value. DLA Land and Maritime alone anchors 186 awards valued at $2.6 million; DLA Construction and Equipment delivers 181 awards valued at $1.9 million. The remaining customer base includes Naval Sea Systems Command (29 awards, $245 thousand), the Department of the Navy United States Pacific Fleet Forces (11 awards, $403 thousand), and Fleet Forces Command Atlantic (13 awards, $271 thousand). This concentration reflects the vendor's established position as a routine supplier into DLA's plumbing components procurement stream rather than pursuit of broad-market civilian or prime defense systems work.

The vendor holds four single-award Indefinite Delivery Contracts with DLA Land and Maritime, each carrying $250 thousand ceilings and expiring at staggered intervals through June 2025. These IDCs—numbered SPE7M021D60DJ, SPE7M321D60DN, SPE7M322D60CB, and the most recent awarded June 2024—serve as the primary vehicle through which DLA places recurring delivery orders for elbow pipes, elbows hoses, tube reducers, and related fittings to DLA depots worldwide.

The vendor operates as a pure prime contractor footprint; 99% of recent awards are prime contracts or IDVs, with only 6 subcontract awards over the source period. Those six subs span ship repair work: Delphinus Engineering (alteration and installation team services aboard USS Blue Ridge and USS Howard, 2025 and 2024), Valkyrie Enterprises (habitability restoration services aboard USS Preble, August 2025), Vigor Marine (mid-term availability work aboard USNS Guadalupe, October 2024), and QED Systems (shock-mount commode procurement for USS Stennis CVN-74 RCOH, December 2023). These subcontract roles involve supplying finished plumbing fixtures and components to prime ship repair contractors rather than engineering or systems integration.

Activity has fluctuated between 28 and 40 awards annually over the past five years, with 40 awards in 2022, 28 in 2023, 36 in 2024, and 33 in 2025. The three awards year-to-date (2026) reflect the early stage of the fiscal year. Combined potential value across all 449 awards stands at $5.4 million, with $4.5 million obligated (82% realization).

NAICS footprint centers on Plumbing Fixture Fitting and Trim Manufacturing (141 awards), Fabricated Pipe and Pipe Fitting Manufacturing (93 awards), and Other Metal Valve and Pipe Fitting Manufacturing (46 awards). The vendor does not hold SBA 8(a) certification, HUBZone status, or SDVOSB designation; WOSB (Woman-Owned Small Business) is the operative set-aside category, though most recent awards are full-and-open or total small business set-asides.
