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.

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.

Can’t say enough about Alpha Environmental! Their costumer service is 10/10, they have really good systems in place, responsive, and professional. The gals in the scheduling department are always so kind! As a real estate agent, I use Alpha’s services numerous times a year. Either it’s for Mold bids, oil tank decommissioning, radon etc. They always do a fantastic job! Thank you for all the work you do!

Wow where do I even begin?? We’re absolutely thrilled by the work Alpha has done for us and we’re eternally grateful to them for ridding our house of asbestos tile! They’re polite, kind, professional — from estimator Filo to manager Dame to Jake, Melvin and the other two guys on the crew (so sorry we didn’t get your names) — you guys are awesome and we so appreciate your help. Our house looks amazing. The peace of mind you’ve given us is priceless. We can’t thank you enough. We’ll certainly be in back in touch if we ever need any of your services again.

Alpha environmental was extremely helpful in navigating me through the process of testing some leftover construction debris for asbestos so I could take it to the dump. Their office manager spent time with me on the phone discussing the options for sample collection, and was extremely friendly in answering my many questions. Sample drop off at the office was easy and the results even came back a few days earlier than expected. Will definitely return if I need more sampling done!

We used Alpha Environmental Services to conduct our home inspection, radon testing, sewer scope and oil tank decommissioning. Every part of their service was really professional. They took so many great photos of the house during the inspection and offered lots of explanation on what they found. Great team. Highly recommend!
