PLIMPTON & HILLS CORP

What PLIMPTON & HILLS CORP does

Plimpton & Hills Corp is a wholesale distributor of plumbing and HVAC supplies founded in 1902 and headquartered in West Hartford, Connecticut. The company sells a comprehensive range of products spanning six core categories: Plumbing Supplies (faucets, pipes, valves, water heaters, well tanks, plumbing parts and tools), HVAC & Air Quality (furnaces, condensers, mini split heat pumps, air handlers, thermostats, filters), Hydronic Heating (boilers, baseboards, zone manifolds, oil burners), Valves & Fittings, Bathroom fixtures, and Kitchen products. Its technology stack is intentionally minimal — a standard contractor-facing e-commerce login portal for orders and invoices, with no proprietary software product — and competitive differentiation rests on physical distribution breadth rather than software.

The company generates revenue primarily through B2B wholesale product sales to plumbing contractors, HVAC contractors, builders, and trade technicians, with pricing structured on a quote/login-gated basis for trade accounts. A secondary consumer-facing revenue stream comes through its 9 Waterware retail showrooms, 2 of which are Connecticut's only Kohler Signature Stores. Plimpton & Hills operates 17 branch locations across Connecticut, Western Massachusetts, and upstate New York, supported by a massive local inventory of thousands of SKUs including commercial boilers, PVF, and niche repair parts, with rapid jobsite delivery and after-hours emergency stock availability as core functional benefits.

The business is privately held and is part of Hills Distribution, a multi-brand distribution platform that also includes Bender Plumbing Supplies, R. Murray and Companies, and Coastal Supply Group. The company targets primary customer segments of plumbing contractors and HVAC contractors, with builders and technicians as secondary segments. Its go-to-market combines enterprise field sales and inside-sales channels serving trade professionals with a direct-to-consumer retail showroom motion under the Waterware sub-brand.
