Service call for main line back up 12/27/21 Maine from septic tank to house trap was blocked. We snaked the line and we got it unblocked. Customer satisfied and house is draining again. Explained to customer that a double wye clean out should be installed outside where the main exits to the septic tank. As well as the house trap to be taken out and replaced with pvc. Customer is not interested in any fixes at this time. Payment and signatures were collected.
