Upon arrival the homeowner showed us to the water heater and hvac unit located in the utility room. These units were discharging into the floor drain of the utility room which has backed up in the past. The customer would like these lines run to the outside through the exterior wall. With the homeowners approval we disconnected and removed the existing discharge lines and opened the wall into the cavity space under the stairs. We then drilled holes in the exterior wall and ran both lines to the outside of the home. We then installed a service weight gasket and stand pipe for the floor drain. With all work completed we tested to confirm proper function, no further issues detected at this time.
