Customer called me out for a 2nd story back up in the toilet the sink and shower. Upon testing the shower was very clogged and holding water. I used the tub gun to clear the blockage. No signs of a mainline present during the visit involving other fixtures. Septic work done on customers home on aug. 12th 2025. Tested all fixtures in bathroom and all seem to be working correctly. Told customer to contact us if any further signs are to present themselves.
