Customer stated drain line is backed up on washer box Found that the drain line on washer box is backing up. After running water upstairs found it all backs up out of washer box there is a main line stoppage somewhere in yard. House does not have external clean out so I’m not able to pinpoint how far into system the clog is. Attempted to run sink auger down washer box to clear clog as I do not have sewer machine on my truck but was unsuccessful. Informed Dan of situation he informed me Katrina is going to submit to resi to have line jetted. Job is not completed.
