The only factory-certified Weil-McLain provider in upstate New York

Weil-McLain recognizes one contractor in upstate New York as its factory-certified startup and service provider: Trinity Plumbing & Drains, the operating company behind Trinity Plumbing NY. New Weil-McLain commercial boilers across the territory are fired, set up and signed off by our technicians, following Weil-McLain’s own startup procedure.
The certification covers every Weil-McLain model, condensing or cast iron, hot water or steam, and it includes warranty work. A warranty claim is handled by the same crew that put the boiler into service, working from the startup readings they recorded.
Factory startup
Before first fire we check the gas supply, venting, condensate disposal, system piping and water quality against Weil-McLain’s installation requirements. Then we light the boiler, set combustion with a calibrated analyzer, confirm gas pressures and prove each limit and safety device. The readings go on a startup report for the owner’s records.
Commissioning
We set the controls up for the building: supply setpoints, outdoor reset, and staging and lead/lag rotation on multiple-boiler plants. When a building automation system will run the plant, we work through the interface with the controls contractor. Facility staff get a walkthrough before we sign off.
Service & warranty
After handover we can stay on as the plant’s service contractor: scheduled maintenance, combustion testing, diagnostics and repairs, plus Weil-McLain warranty work, on every model in the line.

Weil-McLain Commercial — Common Questions
We can, and we are the only contractor in the territory who does. Trinity Plumbing & Drains, the company behind Trinity Plumbing NY, is Weil-McLain's factory-certified startup and service provider for upstate New York, covering every Weil-McLain model.
Yes. Much of our startup work is for mechanical contractors who handle the installation themselves. Tell us when gas, venting, water and power are complete. We confirm the installation is ready, fire the boiler, set it up and complete the startup report. If something has to be corrected first, we write it up so your crew can take care of it.
Both. We maintain and repair Weil-McLain boilers of every age and model, including the cast iron water and steam boilers still heating many upstate buildings, and we handle Weil-McLain warranty work.
