If it’s on a slab, duct scopes can reveal blockage, disconnects, decay, and is a great idea.Scoping a sewer line is a great idea if there are a lot of trees on the property, people drive or park where the line runs, or the house is very old.

A blockage in the city sewer main flooded our dupex's lower unit with two feet of sewage.

He found that the cast iron under the basement has some corrosion and would probably need to be replaced as another blockage would probably happen.

The head pressure of the water will usually push through whatever blockage is in the trap arm between the sink and vertical stack.

The blockage is so severe that this is going to be a several thousand dollar repair.

Mine has a clause that reads: "Tenant shall be charged for repair of drain blockages or stoppages, unless caused by defective plumbing parts or tree roots invading sewer lines."

Have the licensed plumber that was initially called for this issue provide you with a report of the items found as the cause of the blockage and the recommendations, preferably you should also have photos of the items causing the blockage.

They will have to open this area to remove/push the blockage here to get proper flow.

Hi All,I have a property under contract in Pittsburgh that has a blockage 85 feet down the sewer line so the plumbers are unable to confirm whether the line is free of damage beyond that point.
