Customer is experiencing a slow draining toilet in restroom next to exit of house going into a septic tank. Toilet started to backup when we ran an abundance amount of water. Cleanout outside of home heading to septic tank was holding water. Customer has not had septic tank inspected/pumped since they moved in. Recommended they contact septic company to evaluate septic tank. If water is still holding after septic tank is evaluated, customer will call us back out to investigate further. Customer also had so,e concerns about water coming from possible irrigation system creating small puddles. If issue keeps occurring after tank is inspected they will call us out.
