For this job we were called out for 3 drain cleans and a water line to the refrigerator. 2 drain cleans were completed and drains were clear. The kitchen was suspected of needing a drain clearing. But with given information of when problem occurs. I determined that his kitchen line probably needs a vent to solve his solution. Customer has sewage extractor pump that kitchen line directly runs into. That pump is in fine order. 3yo. Thank you for choosing LBA!
