Commercial plumbing equipment

Domestic water, water heating, fixtures, drainage and backflow equipment for commercial buildings. Find sourced companies and the roles that specify, supply, install and service them.

Equipment scope

Commercial plumbing covers domestic hot and cold water, water heaters, booster systems, fixtures, drainage, backflow prevention and water treatment. Code requirements, licensing and testing rules vary by jurisdiction. A company listed under plumbing does not necessarily make or carry every product type.

Plumbing company directory

Independent public reference directory, not a Gulfstream client list. Listings do not imply affiliation, endorsement or current hiring. US research is expanding in verified batches; this is not a complete census. Territories vary by product line; confirm coverage with the company.

Manufacturers design, build and test equipment. Distributors supply equipment, quotations, parts and order support. Manufacturer reps support selections, specifications and represented product lines; some also distribute. Categories overlap only where supported by official sources.
