Count fixtures
Organize connected fixtures and the applicable fixture-unit values for the project or system branch.
Plumbing design software
Plumbing design software for fixture-unit demand and pipe sizing
MEPFlow supports commercial domestic-water workflows from plumbing fixtures and fixture units through demand and pipe sizing, with Canadian engineering practice in mind.
Free to start. Built for mechanical design workflows in Canada and the United States.
Move from isolated calculations to a connected workflow
Domestic-water design becomes slow and error-prone when fixture schedules, demand conversions and pipe sizing live in separate sheets. MEPFlow brings those steps into a repeatable workflow so designers can review the inputs, calculated demand and selected pipe sizes together.
Build demand from fixture counts and fixture-unit values.
Carry diversified demand into domestic-water pipe sizing.
Use a workflow designed with Canadian mechanical projects in mind.
Preserve engineering review for pressure, velocity, code and authority requirements.
A connected domestic-water sizing process
Calculate demand
Convert fixture-unit totals into a diversified flow basis using the selected project method.
Select pipe sizes
Review pipe size, velocity, pressure loss and project constraints before finalizing the design.
Plumbing workflows MEPFlow can support
Canadian mechanical consultants sizing commercial domestic-water systems.
Designers that want to replace fragile fixture-unit spreadsheets with a consistent workflow.
Teams reviewing fixture schedules, branch demand and pipe sizes across a project.
Small firms that need accessible tools without a complex desktop deployment.

ExploreFrequently asked questions
What are plumbing fixture units?
Fixture units are relative load values used to represent the probable demand created by plumbing fixtures. They are converted to a diversified flow using the method required for the project.
Does MEPFlow replace the plumbing code?
No. MEPFlow helps structure calculations, but the designer must apply the code edition, provincial amendments, local requirements and authority interpretations that govern the project.
Is this useful for Canadian plumbing design?
MEPFlow is developed in Canada and its plumbing workflow is intended to support Canadian fixture-unit practice. Always confirm the exact method and code requirements for the project jurisdiction.
Does pipe sizing include every design constraint?
Pipe sizing must consider available pressure, elevation, equipment losses, velocity, noise, water temperature and code limits. Software results are an engineering aid, not automatic approval.
