Sewer Scope Inspection Guidelines

Root penetrations: Any root penetration is a mechanical issue and recommend repair.

  • Per Oregon Plumbing code 718.1:   Building sewers shall be run in practical alignment and a uniform slope of not less than ¼” or 2% toward the point of disposal provided.

Separated joints: If soil or rocks are showing recommend repair. If water lever fluctuates as you down the line, recommend repair.

  • Per Oregon Plumbing code 718.1:   Building sewers shall be run in practical alignment and a uniform slope of not less than ¼” or 2% toward the point of disposal provided.

Holes/large cracks: Are a mechanical issue that needs repair.

  • Per Oregon Plumbing Code 307.1: Sewage or other waste from a plumbing system that may be deleterious to surface or subsurface waters shall not be discharged into the ground or into any waterway unless it has first been rendered safe by some acceptable form of treatment as required by the building official or the authority having jurisdiction.

Sewer pipe sizing: Sewer pipe should always increase in size, never decrease in size. If they decrease, recommend repair.

  • Per Oregon Plumbing code 316.4.2: No fitting or connection that offers abnormal obstruction to flow shall be used.

Pooling: Use water on the way out. Let drain for 3-5 minutes or until no more water is draining. Do pull back inspection. ¼” or more of water, 1 foot in length and has debris build up recommend repair. Water on camera due to grease and debris build up recommend hydro jet.

  • Per Oregon Plumbing code 718.1:   Building sewers shall be run in practical alignment and a uniform slope of not less than ¼” or 2% toward the point of disposal provided.

Leaks: Any liquid entering or leaving the sewer pipe is a mechanical issue, recommend repair.

  • Per Oregon Plumbing Code 307.1: Sewage or other waste from a plumbing system that may be deleterious to surface or subsurface waters shall not be discharged into the ground or into any waterway unless it has first been rendered safe by some acceptable form of treatment as required by the building official or the authority having jurisdiction.

Obstructions: Can be a mechanical issue, if the obstruction cannot be removed. Other options are cabling or jetting the sewer line (always recommend inspecting the sewer line after the cabling or jetting the sewer line).

  • Per Oregon Plumbing code 316.4.1: A fitting or connection that has an enlargement, chamber, or recess ledge, shoulder, or reduction of pipe area that offers an obstruction to flow though the drain shall be prohibited.

Offset joints: Any offset that is more than ½” that is causing debris and water to pool, recommend repair. If joint causes camera to stop and not to continue scope, recommend repair.

  • Per Oregon Plumbing code 718.1:   Building sewers shall be run in practical alignment and a uniform slope of not less than ¼” or 2% toward the point of disposal provided.

Sewer location: Sewer lines in Portland can NOT be connected to another home nor run on to any other property than the home is on.

  • Per Oregon Plumbing Code 721.1: Except as provided in section 721.2, no building sewer shall be located in a lot other than the lot that is the site of the building or structure served by such sewer now shall a building sewer be located at point having less than the minimum distance in table 7-7.

  • Per Oregon Plumbing Code 307.1: Sewage or other waste from a plumbing system that may be deleterious to surface or subsurface waters shall not be discharged into the ground or into any waterway unless it has first been rendered safe by some acceptable form of treatment as required by the building official or the authority having jurisdiction.

Pipe Material: Orangeberg sewer pipe is not allowed. Large dents or even extreme undulation of the sewer pipe can be a mechanical issue if they are contributing to other issues (pooling).
