Weinstein Supply

Weinstein Supply operates as a plumbing-parts specialty distributor from 303 E. 30th Street in Wilmington, Delaware, holding a 4.8-star average across 21 verified customer reviews. The business serves trade professionals and homeowners across much of the Mid-Atlantic, with location listings indicating strong market presence in nearby Pennsylvania communities including Lansdowne, Norristown, and Philadelphia, plus New Jersey branches in Collingswood, Pennsauken, and Vineland. Open Monday through Friday from 6:30 AM to 4 PM, the company facilitates both will-call warehouse pickup and online ordering for registered accounts.

Unlike big-box retailers that stock only common items, Weinstein Supply maintains what multiple reviewers describe as massive inventory, including odd and uncommon parts that other suppliers cannot locate. The counter staff consistently earn praise not just for product availability but for sharing technical knowledge, reviewers note they sell parts AND knowledge, a rare combination in the supply trade. This expertise proves especially valuable when customers need guidance on older systems or nonstandard configurations.

Customer stories from reviews illustrate this expertise in action. Joseph McCormack described needing a shower valve gasket for a 1950s model Speakman, equipment more than seven decades old, and reported the counter team fixed him up with the correct part while offering installation pointers. Sean McGonegal specifically credits the staff for locating odd and uncommon parts for his projects, noting they have consistently solved sourcing challenges that left other suppliers empty-handed.
