Run snake thru clean out access, run until we can see it go thru to septic tee area. Ran thru a blockage close to the septic tank. Ran a camera thru, no additional charge. Camera was going up thru a combo fitting for a clean out access, before that found the pipe to have standing water in it. Recommend customer to remove the pavers to get access to cleans out for us to camera up stream to see what’s causing the issue. Only warranty for today as there is a issue causing back up. Recommend camera and go from there. Escondido area.
