Commercial Plumbing Projects in Indianapolis and Central Indiana
These projects show how Mission Mechanical approaches commercial plumbing work: what the building needed, what our team installed, and what the owner got out of it. Each one is a real project from the Indianapolis area, covering new construction mechanical rooms, commercial water heating plants, backflow prevention, and the code requirements that come with commercial plumbing in Marion County and the surrounding counties.
Mission Mechanical has been a commercial-first contractor since 2002, holding Indiana License CP 10200022 with full general liability and workers compensation coverage. If you are a general contractor, building owner, or facility manager planning a similar project, call 317-733-8686 or request service online.
Our Commercial Plumbing Projects
A new four-story hotel in Castleton needed its entire mechanical room plumbed from the ground up. The project called for a double meter tree, required for plumbing in Marion County, and a hot water system that could handle peak guest demand while delivering safe, consistent temperatures on every floor.
Our commercial team installed a bank of five Rinnai tankless water heaters with a storage tank, a double meter tree built to Marion County requirements with parallel Zurn reduced-pressure backflow preventers, and a master thermostatic mixing valve (TMV) that blends stored hot water down to a safe temperature before it reaches guest rooms. We coordinated with the general contractor to keep the work on the build schedule.
The hotel opened with a code-compliant, fully serviceable mechanical room, completed on schedule. The parallel meter tree lets either side be tested or serviced without shutting off water to guests, and every detail was built to keep the hotel running long after our crew left the job.
