Attempted to clear kitchen sink blockage with k50 sewer machine, installed new badger 5 garbage disposal and re-piped drain piping underneath kitchen sink. Re-pipe included a clean out below the vent because I know will be back here in the future. Kitchen sink is draining at this time, but still has a severe gurgle and starts to back up slightly into the left side sink. This is still happening because theres tons of grease inside the 2” drain line. There is nothing I can about this situation except recommend us coming back to clear the line with the box jetting machine. The homeowner will be contacting the office next to approve the recommend estimates. Also found a leak at the water meter while I was onsite, it is located on town side of the meter. The town will be back out tomorrow to fix this issue.
