10/12/2020 Utility sink for art room in the back of the building has been draining slow and has a sewer smell. Large blockage of paint brushes and paint inside of trap under sink. Used hydro jet to clear out paint buildup inside drain line. Utility sink drain is now clear and draining properly. Followed up drain cleaning with camera Verifying drain is clear. Customer declined replacement of emergency shut off valve. Thank you for choosing CPI PLUMBING AND HEATING.
