Pricing on this estimate is to clear the stoppage affecting the kitchen sink. While the sink in running water will fill up and overflow from the stunner vent connection. Further diagnostics determined that there was a stoppage further down the drain arm off the kitchen sink. Comfort Experts will access the drain line through clean out access on the back wall of the residence. This clean out connects to the kitchen drain line, at this point we will run our sewer machine down the line to break up the obstruction and flush it out. Once the stoppage has been broken up and flushed out we will test the kitchen sink to ensure no further back ups occur.
