Post-Repair
Verification Inspection
A sewer repair is only as good as what the camera shows after it’s done. Bison Plumbing’s post-repair verification inspection documents liner cure, joint integrity, void absence, and restored flow with Picote HD camera footage — producing a written report that confirms the work meets specification. ASTM F1743 compliance for CIPP lining. Independent inspection available for repairs completed by any contractor.
A post-repair verification inspection uses the Picote Solutions HD camera to document that a sewer repair was completed correctly — confirming liner cure, sealed joints, no voids, and restored flow after CIPP lining; or confirming proper installation after pipe bursting or sewer replacement. ASTM F1743 post-installation compliance documentation for CIPP work. Written report and HD footage provided. Also used for independent real estate transaction verification when a seller completes a repair before closing. Part of Bison’s Sewer Camera Inspection services. $150–$350.
The repair itself isn’t the last step — verification is. For CIPP pipe lining, ASTM F1743 specifically includes post-installation inspection as part of the installation process: the liner must be visually confirmed to have fully cured against the pipe wall without voids before the work is considered complete. For any trenchless repair, the camera run after the job is the only objective confirmation that what was installed matches what was specified.
For Birmingham, Troy, and Rochester Hills homeowners investing in premium sewer rehabilitation on properties worth $400,000–$1M+, documentation of the completed work is not optional — it is expected. The post-repair verification report and HD footage become part of the property record, available for future buyers, insurance adjusters, or re-inspection at any point in the home’s lifecycle.
What a Post-Repair Inspection Verifies
Full Liner Cure — No Voids
The camera confirms the liner has fully cured against the host pipe wall along the full lateral length. Voids — areas where the liner has separated from the pipe wall during curing — are identified by position and size. A void in a cured CIPP liner is a structural and infiltration defect that must be documented and addressed before the installation is accepted.
Liner Surface Quality — No Wrinkles
The finished liner interior should present a smooth, continuous surface. Wrinkles in the cured liner — caused by installation technique or inconsistent pressure during curing — create turbulence points that accelerate debris accumulation and reduce flow performance. ASTM F1743 specifies liner surface quality requirements that the post-installation camera run confirms.
Joint Integrity — Sealed Connections
The camera confirms that all joint connections — lateral reinstatements, cleanout connections, and the municipal wye connection — are properly sealed. Improperly reinstated laterals after CIPP lining are a common installation defect; the camera confirms each lateral connection is open and seated correctly in the liner surface.
Restored Flow Diameter
The post-repair camera confirms the full flow diameter has been restored — the liner or new pipe does not have sections where debris, incomplete installation, or material intrusion reduces the available diameter below specification. For CIPP lining, the finished inside diameter is confirmed against the liner specification submitted before installation.
Grade and Alignment
For pipe bursting and sewer replacement, the post-installation camera confirms proper pipe grade — the consistent downward slope that allows gravity drainage. Grade problems in a new pipe installation create low spots where solids accumulate and future blockages form. The camera footage documents grade continuity from cleanout to municipal connection.
No Adjacent Issues Left Unaddressed
The post-repair camera run also confirms the scope of the completed repair — that the work addressed the full defect identified in the pre-repair assessment rather than only a portion of it, and that no new defects were introduced during the installation process. This is the final quality check before the job is documented as complete.
ASTM F1743 — Why Post-Installation Inspection Is a Standard Requirement
🔨 ASTM F1743 and the Post-Installation Camera Requirement
ASTM F1743 is the Standard Specification for Rehabilitation of Existing Pipelines and Conduits by Pulled-in-Place Installation of Cured-in-Place Thermosetting Resin Pipe — the governing specification for CIPP pipe lining installed by pulled-in-place method. It defines the liner material requirements, installation procedure requirements, curing requirements, and post-installation inspection requirements that constitute a compliant CIPP installation.
The post-installation inspection requirement in ASTM F1743 exists because liner cure cannot be verified visually from outside the pipe — it must be confirmed by camera inspection of the cured liner interior. A liner that appears installed from the access point may have voids, wrinkles, or incomplete cure in sections that cannot be detected without a camera run. ASTM F1743 compliance means the installation is not complete until the post-installation camera confirms the liner meets spec.
What ASTM F1743 Requires Post-Installation
Visual camera inspection of the full liner length to confirm: continuous liner-to-pipe wall contact (no voids), smooth interior surface (no wrinkles or deformations), consistent wall thickness, proper lateral reinstatement, and finished inside diameter within specification tolerance.
What Bison’s Documentation Provides
Picote HD camera footage of the full lined lateral with distance markings at each point of interest; written verification report noting compliance or flagging specific non-conformance locations with footage timestamps; and liner specification comparison against the pre-installation design parameters.
Also Covered: ASTM F1216
ASTM F1216 covers CIPP installation by inversion method (the other primary CIPP technique). Post-installation inspection requirements are equivalent — Bison’s post-repair verification serves ASTM F1216 compliance for inversion-installed liners as well as pulled-in-place.
Why the Documentation Matters
ASTM F1743 compliance documentation establishes that the lining work was performed to specification — relevant for warranty claims, real estate transaction disclosure, municipal permit sign-off where required, and any future inspection that questions whether a liner was properly installed.
Four Use Cases for Post-Repair Verification
After Bison’s Own CIPP Lining Work
Post-installation camera inspection is a standard final step in every Bison CIPP lining job — not an add-on service. ASTM F1743 compliance requires it, and the written verification report and HD footage are provided to the property owner as part of the lining deliverable. The report documents that the liner was installed to specification before the job is considered complete and invoiced.
After Any Trenchless Repair — Pipe Bursting, Patching, Spot Repair
After pipe bursting, pipe patching, or any sewer spot repair, a post-installation camera run confirms the repair was completed correctly — proper grade, full pipe clearance, sealed connections, and no adjacent issues left unaddressed. For homeowners investing in trenchless repair at any cost level, the post-repair camera is the objective confirmation that the investment produced the result specified.
Real Estate — Seller Completes Repair Before Closing
When a pre-purchase inspection identified a sewer defect and the seller agreed to complete the repair before closing, the buyer needs independent confirmation that the work was done correctly — not just confirmation that a receipt was produced. Bison provides independent post-repair camera verification that the seller’s contractor completed the repair to specification. The written report and HD footage are provided to the buyer’s agent and attorney before closing.
Independent Quality Check — Another Contractor’s Work
Property owners who had sewer rehabilitation work performed by another contractor — and want an independent camera inspection to confirm the quality of that work — can engage Bison for a third-party post-installation verification. This is relevant when the property is being sold (requiring disclosure of sewer work quality), when the contractor’s workmanship is in question, or when warranty documentation requires third-party confirmation of installation quality.
Why This Matters for Birmingham, Troy & Rochester Hills Homeowners
Documentation and Accountability Are the Standard in Oakland County’s Premium Real Estate Markets
Birmingham, Troy, and Rochester Hills homeowners investing in sewer rehabilitation on properties worth $400,000–$1M+ bring the same expectation to sewer work that they bring to any other major home improvement: proof that what was promised was delivered. A verbal completion confirmation is not documentation. A receipt is not documentation. HD footage of the cured liner interior and a written verification report confirming ASTM F1743 compliance is documentation.
In these markets, sewer repair documentation also has direct transaction value. A post-repair verification report — with HD footage showing a smooth, void-free liner installed to specification — is a disclosure asset when the property is sold. It answers the buyer’s sewer inspection findings before the pre-purchase inspection even raises them. It demonstrates the repair was professionally completed and independently verified — not simply described in a seller disclosure form.
What the Post-Repair Inspection Delivers
HD Video Footage — Full Lateral Run
Picote Solutions HD camera footage of the complete post-repair lateral — from cleanout to municipal connection. Distance-marked at each point of interest. Provided digitally as part of the inspection deliverable. The footage is yours to keep, share with your real estate attorney, forward to your agent, or retain for property records.
Written Verification Report
A written technician assessment of the post-repair camera findings — confirming pass or flagging specific non-conformance locations with footage timestamps, distance from cleanout, and defect description. For CIPP lining, the report notes liner cure status, surface quality, lateral reinstatement, and inside diameter against the liner specification. Formatted for property records, real estate transaction use, and warranty documentation.
ASTM F1743 / F1216 Compliance Notation
For CIPP lining verification, the report notes whether the post-installation inspection findings are consistent with ASTM F1743 (pulled-in-place) or ASTM F1216 (inversion) compliance requirements. This notation is the documentation that the installation meets the governing specification — not just that a camera was run.
Pre/Post Comparison if Bison Performed the Repair
When Bison performed the repair, the post-repair verification report is produced as a companion to the pre-repair camera assessment — documenting the defect conditions identified before repair and confirming each defect has been addressed in the post-repair footage. This before-and-after documentation is the most complete record of a sewer rehabilitation program available.
The Post-Repair Inspection Process
Schedule — After Repair Completion and Cure
For CIPP lining, the post-installation inspection is scheduled after the liner has fully cured — cure time varies by liner system and ambient temperature (typically 2–6 hours for ambient-cure liners). For pipe bursting and other repair types, the inspection is scheduled after installation is complete. Contact Bison to coordinate timing when your repair is scheduled.
Picote HD Camera Run — Full Lateral Length
The Picote Solutions HD push camera feeds the full lateral from cleanout to the municipal connection — recording footage of the complete post-repair interior with distance measurement at each point of interest. The camera runs the full lateral length regardless of where the repair was performed — confirming both the repaired section and the adjacent pipe condition.
Findings Assessment — Specification Comparison
Camera footage is reviewed against the repair specification: liner specification for CIPP work; installation parameters for pipe bursting and replacement. Findings are assessed for ASTM F1743 / F1216 compliance for lining work, and against general quality criteria for other repair types. Any non-conformance is identified with footage timestamp and distance from cleanout.
Written Report and HD Footage Delivered
The written verification report and HD video footage are delivered digitally — typically within 48 hours of the inspection appointment. The report is formatted for property records, real estate transaction use, and warranty documentation. For Bison’s own lining work, this report closes out the installation as ASTM-compliant before final invoicing.

A post-repair verification report from a CIPP lining or sewer replacement job is a permanent property document — not a temporary service receipt. File it with your home improvement records alongside the pre-repair camera assessment, liner specification, and warranty documentation. When you sell the property, this documentation demonstrates the sewer lateral was professionally rehabilitated and independently verified — answering buyer due diligence questions before they become negotiating points. Contact Bison to schedule a post-repair inspection.
