Drain & Sewer Warranties
Workmanship guarantees on every drain and sewer job.
Two types of coverage
Drain and sewer work can involve two separate kinds of warranty, and it helps to understand which one applies to a given issue. The first is a manufacturer's warranty, which covers defects in materials used during a repair or installation, such as pipe, fittings, or another installed component. The manufacturer sets the terms for that coverage, and it applies specifically to product defects rather than how the product was installed.

The second is our workmanship guarantee, which covers the labor and installation performed by our technicians. If a repair fails because of how it was installed or completed, rather than a defect in the material itself, that falls under workmanship coverage. Determining which category applies starts with identifying the actual cause of the failure, since a cracked fitting and a poorly sealed joint point to different kinds of coverage.
How a warranty claim works
If a drain or sewer repair develops a problem after the work is finished, call the shop first rather than contacting a manufacturer directly. Describe what is happening and when it started, and bring up the original service so the history can be pulled and reviewed. A technician can usually determine during a visit whether the issue points to a material defect or a workmanship concern.
Keep your invoice, model and serial numbers for installed equipment, along with any part information noted on the invoice, since this speeds up determining which type of coverage applies. For camera inspections performed before a repair, keeping the video on file is also useful if a question comes up later about the condition of the line at the time of the original work.
What to expect
A returning backup does not by itself identify a warranty issue. Roots in another section, a new obstruction or a problem at the repaired connection can produce similar symptoms. The cause needs to be established before the applicable coverage is discussed. The technician will explain during the visit whether a reported issue connects back to prior work or represents a separate, new problem requiring its own diagnosis.

Frequently asked questions
How do I know if my issue is covered by workmanship or manufacturer warranty?
A technician reviews the cause of the failure during a visit. Material defects point to manufacturer coverage while installation related issues fall under our workmanship guarantee.
Who do I call first if a repaired drain fails again?
Call Iron Horse directly rather than contacting a manufacturer, so the original service history can be reviewed and the correct coverage identified.
What records should I keep after a sewer repair?
Keep the service invoice and any camera footage or part information from the job, since these help confirm what type of coverage may apply if an issue comes up later.
Does warranty cover a brand new clog in a different part of the line?
A new clog elsewhere can have a different cause from the original repair. Call first so the cause and applicable coverage can be reviewed rather than assuming the symptom identifies a warranty fault.
