Plumbing specs name specific pipe, fixture, and equipment manufacturers. Look for: - Pipe manufacturer substitutions (Charlotte Pipe, JM Eagle, Viega, Watts, Nibco) - Fixture manufacturer substitutions (American Standard, Kohler, Sloan, Zurn, Chicago Faucets, Elkay, Moen, Delta Commercial, T&S Brass) - Water heater manufacturer substitutions (A.O. Smith, Bradford White, Rheem, Lochinvar, PVI) - Valve manufacturer substitutions (Watts, Nibco, Apollo, Milwaukee Valve) - Water cooler/fountain manufacturer substitutions (Elkay, Halsey Taylor, Oasis, Haws) - Backflow preventer manufacturer substitutions (Watts, Zurn Wilkins, Apollo, Febco) - Grease interceptor manufacturer substitutions (Zurn, Jay R. Smith, Watts, Schier) - Pump manufacturer substitutions (Grundfos, Bell & Gossett/Xylem, Armstrong, Taco) Full guide: https://deviationcheck.com/divisions/22-plumbing/manufacturer-substitution/ ### Performance Specification Gap (default grade: Blocker) A measurable performance property in the submittal (rating, capacity, tolerance, efficiency) does not meet what the spec requires. Key performance parameters in plumbing submittals: - **Pipe pressure rating** (SDR rating, schedule number, psi working pressure) - **Pipe material specification** (Type L vs Type M copper, Schedule 40 vs 80 steel/PVC, CPVC, PEX class) - **Flow rate (GPM)** at design conditions for water heaters and fixtures - **Temperature rise** (degrees F at rated flow for water heaters) - **Thermal efficiency** (%) for water heaters (condensing vs non-condensing) - **First-hour rating** and recovery rate (GPH) for storage water heaters - **Input capacity** (BTU/hr for gas, kW for electric water heaters) - **Storage capacity** (gallons) - **Fixture water consumption** (GPF for water closets and urinals per EPA WaterSense, GPM for lavatory faucets and showerheads) - **Backflow preventer rating** (ASSE 1012, 1013, 1015, 1024 per hazard classification) - **Grease interceptor capacity** (GPM flow rate, grease retention in lbs) - **Roof drain flow capacity** (GPM at design head) - **Expansion tank volume** (gallons, acceptance volume at operating pressure) - **Insulation thickness** for hot water piping (per ASHRAE 90.1 Table 6.8.3) - **Pipe velocity limits** (fps for copper, steel, plastic per manufacturer/code) Full guide: https://deviationcheck.com/divisions/22-plumbing/performance-specification-gap/ ### Missing Certification or Compliance Documentation (default grade: Fix and Resubmit) A required listing, test report, certification, or compliance document is absent from the submittal package. Required certifications in plumbing submittals: - **NSF/ANSI 61** certification (drinking water system components - required for all products contacting potable water) - **NSF/ANSI 372** compliance (lead-free per Federal Safe Drinking Water Act, 2014) - **ASSE standards** for backflow preventers and safety devices (1012, 1013, 1015, 1017, 1024, 1047, 1048, 1070) - **ASME certification** for water heaters and storage tanks - **UPC (Uniform Plumbing Code)** or **IPC (International Plumbing Code)** compliance - **UL listing** for electric water heaters (UL 174 / UL 1453) - **CSA certification** for gas water heaters (ANSI Z21.10) - **EPA WaterSense** certification for water-efficient fixtures - **IAPMO listing** (cUPC mark) for plumbing products - **ADA compliance** documentation for accessible fixtures (ANSI A117.1) - **LEED water efficiency** documentation (fixture flow rates, WaterSense compliance) - **Seismic certification** for water heaters and equipment anchorage (IBC/ASCE 7) - **Buy America** compliance (for federally funded projects, ARRA) - **Scald protection certification** (ASSE 1016, 1017, 1070 for mixing valves and thermostatic valves) Full guide: https://deviationcheck.com/divisions/22-plumbing/missing-certification/ ### Aesthetic Deviation (default grade: Fix and Resubmit) A visible attribute (color, finish, texture, profile) differs from the spec or the architect-approved sample. - Fixture color (white, bone, biscuit, black per manufacturer line) - Faucet finish (polished chrome, brushed nickel, satin stainless, matte black) - Fixture style and model appearance (ADA-compliant vs standard, wall-hung vs floor-mount) - Water cooler/fountain finish and configuration (wall-mount, bi-level, bottle filler) - Exposed piping finish (chrome-plated, stainless steel) in accessible areas - Access panel finish and type Full guide: https://deviationcheck.com/divisions/22-plumbing/aesthetic-deviation/ ### Detail or Installation Mismatch (default grade: Fix and Resubmit) The submitted detail, dimension, anchorage, or installation method differs from what the spec or drawings require. - **Pipe material** mismatch (Type L vs Type M copper, cast iron vs PVC for DWV, CPVC vs PEX for domestic water) - **Joining method** differs (solder vs press-fit/ProPress vs brazed for copper; hub vs no-hub for cast iron; solvent weld vs mechanical for PVC) - **Pipe size** differs from design drawings - **Water heater vent type** (direct vent vs power vent vs atmospheric draft) - **Trap size** differs from code minimum - **Fixture rough-in dimensions** differ (affects coordination with walls and structure) - **Valve type** differs (gate vs ball vs butterfly, full port vs standard) - **Expansion tank** size or pre-charge pressure differs - **Insulation type or thickness** for hot water piping differs - **Floor drain body type** (adjustable vs fixed, sediment bucket vs open) - **Water hammer arrestor** location or sizing differs - **Mixing valve type** (thermostatic vs pressure-balancing vs combination) - **Domestic water booster pump** type or capacity differs Full guide: https://deviationcheck.com/divisions/22-plumbing/detail-installation-mismatch/ ### Submittal Package Incompleteness (default grade: Fix and Resubmit) A required submittal element (cut sheet, schedule, calculation, sample) is missing, leaving the package unreviewable as submitted. Commonly required items in Div 22 specs: - Plumbing riser diagrams - Isometric drawings for waste/vent systems - Fixture schedule with rough-in data and GPM/GPF ratings - Water heater performance data at design conditions (input, output, recovery, efficiency) - Backflow preventer product data and test certification - Pipe material and fitting schedule - Valve schedule with size, type, and service - Insulation schedule for piping - Seismic bracing calculations and anchorage details - O&M manuals for equipment - Warranty documentation - Grease interceptor sizing calculations - Domestic hot water demand calculations - Expansion tank sizing calculations - Plumbing fixture spec sheets showing code compliance (ADA, WaterSense) --- Full guide: https://deviationcheck.com/divisions/22-plumbing/submittal-package-incompleteness/ ## How Division 22 deviations are graded - **Pipe material below spec pressure rating:** BLOCKER (burst risk, property damage, injury) - **Missing NSF/ANSI 61 for potable water components:** BLOCKER (health code, Safe Drinking Water Act) - **Lead-free non-compliance (NSF 372):** BLOCKER (Federal law, Safe Drinking Water Act 2014) - **Water heater capacity below design load:** BLOCKER (will not meet demand) - **Backflow preventer grade below code/hazard requirement:** BLOCKER (cross-contamination, health risk) - **Fixture water consumption exceeding code maximum:** BLOCKER (plumbing code violation) - **Missing ADA compliance for accessible fixtures:** BLOCKER (ADA/ANSI A117.1 requirement) - **Missing seismic anchorage for water heaters where required:** BLOCKER (IBC, California Health & Safety Code) - **Missing scald protection (ASSE 1016/1017) where spec requires:** BLOCKER (injury risk) - **Pipe material mismatch (lower grade):** BLOCKER if pressure-rated service, FIX_AND_RESUBMIT if gravity drain - **Fixture color mismatch:** FIX_AND_RESUBMIT (aesthetic) - **Missing WaterSense certification where spec requires:** FIX_AND_RESUBMIT (LEED/code compliance) - **Insulation thickness below ASHRAE 90.1 minimum:** FIX_AND_RESUBMIT (energy code)
