    Plumbing field brief

    Plumbing calculations and code context you can defend on inspection day.

    Common field pain points

    • IPC/UPC confusion across jurisdictions.
    • Rework from wrong sizing assumptions.
    • Estimate loss when field signal drops.

    Built for inspection day

    • Drain Sizing Wizard with IPC/UPC auto-selection.

    Before you DIY plumbing

    Sewer gas, scalding hot water, frozen pipes, gas-fired water heaters, and trenching for service lines all have stop lines. Know them before you cut into a wall or drain a system.

    Emergencies — stop the damage

    Shut off water first, then power if anything electrical is wet.
