Commercial Plumbing & Backflow Testing
in Saint John, NB
Bates Plumbing & Heating serves Saint John's commercial and industrial sector, large-scale mechanical projects, backflow prevention programs, and complex plumbing work for the port city's demanding built environment.
Industrial-Grade Plumbing for Saint John's Commercial Base
Saint John is one of Atlantic Canada's most active industrial and commercial centres. The port, the oil refinery, manufacturing facilities, heritage commercial buildings in Uptown, and a growing hospitality sector all create demand for a plumbing contractor that can work at scale, not just change a fixture or clear a drain.
Bates travels to Saint John for larger scopes: full mechanical rough-ins on new commercial builds, multi-system retrofits in heritage properties, industrial drain and waste systems, and backflow prevention programs for facilities that require annual certified testing. These are the projects where experience, licensing, and proper documentation matter most.
Saint John's older building stock, particularly in the Uptown core, presents unique challenges: aging cast-iron waste systems, lead service connections flagged for replacement, and infrastructure that predates modern plumbing codes. We've seen it all over 50+ years in the trade, and we know how to bring these buildings into compliance without tearing them apart unnecessarily.

Backflow Prevention for Industrial & Commercial Facilities
Industrial and commercial operations in Saint John face some of the strictest backflow requirements in the province. Any facility with cross-connections between potable and non-potable systems, including cooling towers, process lines, irrigation, and fire suppression, must have certified backflow preventers tested annually by a qualified tester. Bates holds that certification and provides the documentation your facility and the municipality require.
