Sanitary Drainage Installation and Pre-Cover Record

Use this record for

Ordinary building sanitary plumbing/drainage installation records for defined pipe segments, connections and inspection before concealment/backfill where applicable.

Outside this record: Design sizing or gradients, universal levels or test criteria, on-site wastewater treatment, trade waste systems, industrial/process piping, gas, fire and public utility networks unless separately scoped and sourced.

No gradient, invert tolerance, test method, pressure/head, duration or witness/release rule is prefilled. Confirm the jurisdiction, current approved drawings, project-adopted standard and inspection notice before covering work. WA Bulletin 133 is WA-specific guidance only.

Collect these project inputs first

Approved sanitary drainage plans and schedules: Identify current segment layout, nodes, sizes, levels, interfaces and revision.
Project material and joint submittals: Defines approved components, joint systems and installation requirements.
Project test specification and adopted standard: Supplies local method, acceptance criteria and any required test record; the form has no universal test settings.
Inspection, backfill and notification schedule: Assigns pre-cover checks, notice periods, witness role and any external notification/release.
As-built and nonconformance workflow: Defines required marked-up drawings, photo evidence, repair records and disposition.

How to use the checklist

Use a separate record for each identifiable segment or project-defined inspection lot; keep different systems and criteria separate.
Check current drainage drawing and node-to-node identity, then record actual observed geometry and interfaces against project references.
Record test method, values and outcome only from the approved procedure and actual test report; attach the source evidence.
Before backfill/concealment, link required inspection/notice, test, repairs, photos and as-built markups.
Leave any unclear criterion, missing test or covered uninspected extent open for project disposition.

Checks and the records they need

Fill project criteria from approved documents before inspection. The fields below show what the downloaded form asks you to record; the web page does not save or approve site results.

The files provide 8 blank entry rows. Continue on another blank copy as needed; the web page does not record site entries.

SD-01 · Drainage section identity and approved geometry

Drain line/branch ID, upstream/downstream nodes, drawing revision, pipe material/size, design direction and segment limits.

How to check: Trace the installed segment between identified connection points against approved drainage layout and schedule; record design references for any checked levels/grade.
What defines acceptance: Each observation belongs to a defined segment and current drawing; geometry and any numerical criteria are assessed only against project-approved design documents.
Project document to cite: Current approved project drawings, specification, adopted service standard and inspection/test plan; record exact document, revision, clause/detail and affected segment.

If a discrepancy is found: Identify affected segment and resolve drawing/revision or alignment conflict before concealment or acceptance.

SD-BED · Exposed trench, bedding and pipe support

Record trench condition, installed bedding and pipe support before they are concealed, where below-ground work is included.

How to check: Compare exposed work with the approved trench, bedding and embedment detail and relevant product instructions. Identify unstable formation, voids, debris, pipe movement and civil-work interfaces for project disposition.
What defines acceptance: Observed trench support, bedding and embedment correspond to the approved project detail. Material, thickness, cover and compaction requirements come from the actual applicable sources; this record supplies no default value.
Project document to cite: Enter approved drawing/detail and revision, applicable civil or geotechnical specification, and product installation instruction.

If a discrepancy is found: Keep the affected location identifiable, document the discrepancy and obtain the project-assigned disposition and reinspection before covering.

SD-02 · Pipe, joint and connection workmanship

Pipe/fitting identity, joint type and visible condition, connection orientation, damage, contamination and transition to fixtures or other drains.

How to check: Inspect accessible work and compare joints/fittings with approved product submittal, installation details and method; capture photographs or location references where useful.
What defines acceptance: Installed components and observable joints correspond to the approved project system and are free of unresolved visible damage/defects; this blank form sets no dimensional or joint acceptance limit.
Project document to cite: Current approved project drawings, specification, adopted service standard and inspection/test plan; record exact document, revision, clause/detail and affected segment.

If a discrepancy is found: Record exact location and item, protect/segregate as required by project process, and obtain disposition before concealment.

SD-03 · Access, support and service separation

Inspection/cleaning access, supports/restraints where visible, penetrations and separation from stormwater or other systems at interfaces.

How to check: Compare accessible installation with approved coordination/service drawings and manufacturer/project details; identify access points and cross-system interfaces.
What defines acceptance: Required access and interfaces are identifiable and installed to current project details; keep stormwater and sanitary service identities distinct; any proposed cross-system connection needs verified design and applicable authority approval.
Project document to cite: Current approved project drawings, specification, adopted service standard and inspection/test plan; record exact document, revision, clause/detail and affected segment.

If a discrepancy is found: Document the interface and obtain project/design direction for missing access, unapproved cross-connection or unresolved coordination issue.
