Customer called in because of mainline stoppage at two different sites. A campsite and the mainline right before the septic. Ran drain inspection equipment down cleanout and found stoppage at approximately 50 foot. Ran drain cleaning equipment to approximately 60 feet. Saw and hear water drain. Ran camera down and found standing water still inside of piping. Removed septic lids and saw water above secondary baffle. Removed baffle filter and witnessed water start to drain. Cleaned off baffle filter and reinstalled. Line is clear but approximately 5-10 feet before baffle standing water is still present inside of piping. Ran drain cleaning equipment down secondary cleanout at campsite. Found standing water inside of pipe. At multiple places. No signs of stoppage found. More drain inspection work required.
