Customer called in with backed up drains. Arrived on site and inspected the issue. The customers drain are backed up indicating a main line blockage. Provided pricing to perform camera work to locate the clog. The customer accepted the pricing. Pulled the septic lids and clean-out cover. There is standing water inside the clean-out. Used a sewer camera to inspect the mainline. The mainline from the home to the septic tank is back graded and is unable to properly flow to the septic tank. I was able to clear the obstruction and get the house to drain, but the main line is still full of water due to the improper pitch of the piping. Provided pricing to install a new side sewer pipe from the home to the septic with a new clean-out at the proper pitch was provided. The customer accepted the pricing. Locates have been called and we will begin work once the piping has been excavated by the customer. Thank you for choosing CPI Plumbing & Heating!
