My new next door neighbor, after my old one married a very competent guy
(who is by himself redoing their bathroom from the walls up) , noticed
that the basement sink, which overflows when the stream overflows
enough, is on the other side of the room from the sump pump. AND that
the floor doesn't slope towards the sump pump.
He made it sound like a normal/good cement basement floor would have
sloped a bit from the sink to the sump. So that overflow water ran to
the sump instead of spreading out. Is that true?
Or do they just make them flat all the time?
Most every basement I've seen slants towards a floor drain. In some
cases the floor drain goes to the city sewer system, which can be a bad
thing if the city sewers tend to back up during heavy rains. Some floor
drains go to the sump pit. In my previous house, 5 years ago, the drain
was to the city sewers and if we lost power, the lift station, about a
block away, would stop pumping and the sewers of the lower lying lots
would back up. I had a plug in mine because of that. But, I noticed
that they recently installed a huge backup generator by the lift
station. The public works director always told me that it would require
a huge pump to start the 100HP motors, but I guess they decided to do
it. Now, in my present home, the floor is perfectly level and there is
no sump. But I am half way up a small mountain. If somehow water were
to get on the basement floor, the door works good for drainage, as half
of the basement is at ground level.

Every below-ground basement in Baltimore County or maybe Maryland has to
have a sump and sump pump since before this house was built. The sump
was planned. I'm sure it was allowed for, by putting the black plastic
sump "barrel" in place before the floor was poured.
So my neighbor was right. I thought he was knowledgable It's good to
know for sure, for when he tells me I should do something.
The "barrel" comes with a plastic or rubber lip that sticks almost a
half inch above the floot. I put a few holes in it so that I could
sweep the water into the sump, but that didn't work well. Soon after,
I stopped trying to clean up floods (they ar e never more than 1/4") ,
and I just let them dry out by themselves. It's much easier.
Thanks, and thanks Art.

I've lived in several homes with sump pumps and many more. Around here,
NJ suburbs, the floors don't pitch toward them. One obvious problem is
that basement floors typically are large and you couldn't rely on one
sump pit in a corner working to take water from the floor a long ways
from it. It would have to have a big height difference from one end
of the basement to the other. People frequently want to finish basements,
not have a slanted floor, it would make the concrete job harder too.
Even new construction here that I've seen, no pitch of the floor towards
the sump. House I'm living in now, water heater sprang a leak and it
didn't head to the perimeter drain which was just a few feet away.
If it's a floor drain, centered in a floor to take water away from
the surface, then I agree the floor should be pitched.
