AI drawing review for plumbing contractors
Detect pipe routing conflicts, verify fixture rough-in dimensions, and coordinate riser diagrams automatically, all from your PDF drawing set.
What slows down plumbing contractors
The drawing problems that quietly drive plumbing rework and change orders.
Pipe Routing Conflicts
Waste, vent, and supply lines clash with structural elements, ductwork, and other trades in wall cavities and ceiling spaces.
Fixture Rough-In Errors
Rough-in dimensions from architectural plans often conflict with manufacturer specifications and accessibility requirements.
Riser Coordination Gaps
Riser diagrams frequently do not match floor plan layouts, leading to pipe sizing errors and missing connections.
How Helonic helps
Plumbing-specific drawing review across waste, vent, supply, and gas systems.
Waste and Vent Coordination
Verify that waste and vent piping routes clear structural beams, ductwork, and other obstructions while maintaining required slopes and code-compliant configurations.
Water Heater Sizing Verification
Cross-reference water heater capacity against fixture count, hot water demand calculations, and piping layout to ensure adequate supply for the building.
Fixture Count vs Pipe Sizing
Automatically calculate fixture unit loads and verify that pipe sizing on riser diagrams and floor plans supports the total demand at each branch and main.
Riser Diagram vs Plan Matching
Compare plumbing riser diagrams against floor plans to catch missing connections, mismatched pipe sizes, and inconsistent floor-to-floor routing.
Gas Piping Coordination
Review gas piping routes for clearance from electrical panels, air intakes, and operable windows while verifying sizing against connected BTU loads.
Common issues we catch
The plumbing conflicts and code gaps Helonic surfaces on every drawing set.
Piping & Fixtures
- Pipe slope violations below minimum code requirements
- Missing cleanout access at required locations
- Fixture unit miscounts affecting pipe sizing
- Inadequate venting causing drainage problems
Safety & Coordination
- Cross-connection risks between potable and non-potable systems
- Missing backflow prevention at required locations
- Gas piping clearance violations near ignition sources
- Storm drain connections missing or undersized
