Arrived at customers house for a call about a possible backed up/clogged/frozen mainline. After sticking a camera snake down both sides of house trap going up to main toilet and down to septic tank, no clogs leaks or splits were found. Open septic tank lid and saw that toilet in apartment above garage flushed straight into septic tank without hesitation. Also shut off main valve in house to garage for the customer since they are no longer using this domain. Customer is very satisfied with services provided today.
