I had a section of concrete removed from my garage to install a sump drain
so it would be possble to wash the car in the garage in the winter.
The dirt under the concrete in like concrete, I need to go down at least 3
ft, the soil is clay, I was think of watering it down a bit.
I must be missing something here. In your _drain020.jpg_, it looks as if
your floor slants towards the door, with the one side of the concrete floor
rolled away from the wall. Is this an obtical illusion? I know here in my
area, it's common for the floor to be poured with a 3" height difference,
the lowest point at the garage door. If it's not an illusion, exactly what
will the sump accomplish on a totally flat floor? Also, is this for a sump
pump, or where do you plan to have the water exit?
Curious minds want to know. TX
The floor has an 8 in drop from the front of the garage to the door, The
garage is 30 ft deep so no water will flow out the garage door, as there is
plenty of room ahead of the drain to wash the car.
No optical illusion the floor does slant away from the wall.
I plan on useing an extra old shop vac to remove the water, then dump it in
Ok, call me feeble minded, but now I'm really confused. It looks like you
will have a grate approx. 3' in front of the door. Are you saying the water
will run into the sump, but it wouldn't run to the door and out if the door
was lifted 1/2"? I'm just trying to understand why you would go through all
the trouble of putting in a sump if all you had to do was crack the door
Doesn't sound like fun using a shop vac, if you absolutely must have a sump,
I would put in an electric pump with proper piping.
No water will escape the garage if the door is open a 1/2 inch, washing the
car when the outside temp is in the single digits tend to ice up the
This is a spare garage as I have a 2 car attached on the upper level of my
ranch, so other than washing the car in cold weather the garage is empty.
I think I can wash my car and only empty the sump once, as the water will
not be running constant.
