This is one of those clogs that can turn into a much bigger problem if it’s ignored.
The AC condensate line was draining directly into this bathroom sink line, and over time it created a heavy biofilm buildup that restricted the drain. The scary part is the AC keeps producing condensation, so if the drain completely backs up, that water has nowhere to go but up.
We cleared the line with a combination of our drain machine and RIDGID FlexShaft, then tested everything to make sure both sinks and the AC condensate were draining properly again.
