Fix slow draining/backed up kitchen sink
1.200 kr.
Our kitchen sink is not draining properly and backs up / holds water in it. This is especially noticeable when the dishwasher is also running and no water goes down the drain - water from dishwasher has also come back up the kitchen sink. We have removed and cleaned the u-pipe below the sink but there were no obstructions or clogs. We suspect there is something wrong with the pipe setup (poorly connected, no air vent etc).
