Customer basement shower and toilet drain are backing up whenever customer is taking a shower. The drain is bubbling and backing up. I remove the basement toilet to get access to the pipe. Ran a 30 feet of Chain knocker, snake and clear out the blockage. I put in the camera and found that the basement of the house Are feeding into the back of the house septic and then the top of the house is feeding into the front of the house septic. Recommended customer to have both of the septic tank pump.
