Customer called me out for multiple fixture back up. Upon arrival looked at there septic tank which has standing water in it and around it. I tested the fixtures that were backing up and the only one that wouldn’t drain was the downstairs basement toilet. I ran an ungodly amount of water in the house and was getting flow to the clean out outside. I tried auguring the toilet but with no success. Customer wanted to get septic company out first before trying to pull and clear the toilet with a cable machine. Toilet was not draining at all during visit. (customer said she would call back when ready to proceed)
