This house had a lot of jury rigged components and it was difficult to follow the piping at the sub floor.
The pipe in question seemed to be from under the kitchen sink and terminated at the side exterior. (You had to be there) Seemed like an ARV valve is all that is needed. I thought it was the inferior basement drainage sump pump but they discharged that about 75 feet to the floor drain with a hose.
The same piping was used as a raceway for the electrical wires.
ANYONE HAVE ANY GOOD VERBIAGE FOR IMPROPER USE OF PLUMBING PIPES FOR ELECTRICAL RACEWAYS?
PVC used for dryer vent to.
Got to love the weekend warriors!!
One note about Cleveland. Most houses are worse than are sports teams!!
