Plumbing for Macedonia Warehouse, Flex and Light Industrial Spaces

Typical Scope in a Flex or Warehouse Building

Most of these buildings start as an open shell with a water service, a sewer stub and a gas service at one wall. The tenant's plan determines what gets built from there. Common items include:

• Men's and women's restrooms, or single-user accessible restrooms, in the office area
• A break room with a sink, dishwasher and refrigerator water line
• A mop sink or service basin for the warehouse floor
• An emergency eyewash or shower where the tenant's operations require one
• Hose bibs and wash-down connections for the shop floor
• Gas piping to unit heaters, radiant heaters or rooftop units
• A water heater sized for the restroom and break room load

Cutting Slab for New Restrooms

Warehouse floors are thick, and the sewer stub is often far from where the tenant wants the restrooms. Adding them means saw-cutting a trench, excavating, laying drain pipe at the correct slope back to the stub, testing it and having it inspected before the concrete is patched. Long runs require careful grade planning, because the drain has to keep falling the entire way.

We walk the space early to locate the stub and measure its depth. That one detail can decide where the restrooms should go, and putting them close to the stub can save a lot of concrete work.

Backflow Protection and the Water Service

Commercial and industrial tenants frequently need backflow prevention, either at the building's water service or at specific equipment, depending on what the space will be used for and what the water provider requires. Process equipment, boiler feeds, irrigation and chemical dispensing are common triggers. We install the devices the approved plans call for and make room for annual testing access.

If a previous tenant left plumbing that does not meet current requirements, such as missing backflow devices or improper connections, it is easiest to correct during the build-out. See our code violation repairs page for more.

Heating and Hot Water in Large Open Spaces

Warehouse heating often runs on gas: hanging unit heaters, infrared tube heaters or rooftop units. Those appliances can draw a lot of gas, and the piping runs along high walls or roof structure. We size the system for the full heater load and coordinate with the HVAC contractor on connection points. Our gas line installation page explains how sizing works. For the restroom and break room, a small tank or tankless heater is usually enough; see our water heater page.

Working on a Project at a Distance

Macedonia is near the northern edge of our service area, so we plan these jobs carefully. We batch work into full days on site, confirm with the GC that the space is ready before each phase, and line up inspection dates in advance so a trip is never wasted. For new buildings rather than tenant improvements, see our new plumbing installation page, and our general construction approach is described on our construction services overview.
