In NE Ohio we can have some sub freezing temperatures. Why would you place a sump in a garage (right by the overhead door) when there are areas in the basement like under the steps, closet or a corner.
There was an electric heater with a arced outlet. Dumb
Lets pay for heating the garage to keep the sump from freezing. Dumb
The interior system was only on half the walls. Dumb.
The efflorescence shown is on a wall that was not done. This is were I would of placed the sump. Under the steps. Out of sight with a door, easy access.
The condo also had an irrigation system. Dumb Lets add water to a home that already has a water problem.
The grade is level at the garage and goes up towards the rear of the home.
There is a large negetive grade in back and at the side.
The basement walls are all below grade and the garage is mostly above grade but there are portions of the garage towards the back that are partially below grade or at the frost line.
