For this job I performed an evaluation. Upon arrival homeowner said that the system had been working great but they did notice that there was draining coming out the secondary drain line in front of the house and it had been going on for a while. I checked the primary drain line with the gallon of water and quickly notice that it was clogged. I unclog the drain line and rebuilt their p-trap. I tested the drain line with two gallons of water no abnormalities were noted. I did offer a drain safety homeowner declined at the time but approved the drain clear and repair. Delta's were within normal limits system appear to be running with no issues. Homeowner declined membership at the moment.
