Customer has concrete in the sewer lines and would like to have the pipes cleared of any and all debris, there is access to the vent from the roof. Recommend a camera down the sewer vent to assess the extent of debris, other recommendation is to hydro-jett the sewer line trying to the clear as much of debris as possible. The only choice past these steps is knocking up the concrete and removing the blocked pipes, if we need to take this step then another trip with the camera needs to be done to determine where and how to schedule this job. Left estimates for Jason from the roofing company, the customer will contact us when they decide what they want to do.
