Last night as I was working in my basement shop the central A/C kicked
on. After about 30 minutes, I happened to glance down to see a
growing puddle around the base of my furnace. The water was coming
from the condensation drain on the A/C. Something had plugged the
drain and the water was bubbling out on the floor.

Near as I can tell, whoever installed the centrail A/C in my house
just punched a hole through the floor and glued a piece of PVC pipe in
as a drain for the condensation. The water is supposed to just wick
away under the concrete pad, I guess. It's sandy soil tens of feet
deep, and on top of a hill, so there's excellent drainage. Still, I
don't like the arrangement.

Furnace is in the exact center of the basement, with pedestrian
traffic all around. Sump crock is in the far corner. Can't get to the
sump crock without either laying pipe across where people walk, or
busting up the floor. Don't like either option.

Any alternatives, like a small sump and pump that I can use to lift
the water up and over, along the joists, and down into the sump crock
in the corner?

Lowe's has a condensation pump at some stores. Do a search on the Lowes
web site for: condensation pump. The is one item that caught my eye,
which is Lowe's item #189246. Float control, plastic pipe attachment, 2
quart holding tank.

Note the Customer ratings is only 3.4. (out of 4.0) It is just a pump,
tank and float control. It should be at least 3.8.

The condensate pump at the HD web site has a higher customer rating.

It's based on only two reviews - that doesn't necessarily mean much.

Condensate pumps die. I'd clear the current drain and make it work again. A
condensate pump could be used to pump "overflow" if the current drain plugs
again, or you could set the drain up with an overflow switch which would sound a
"clean me" alarm.
