I want to have crawlspace drainage installed. My crawlspace is approximately
a rectangle with some protrusion (e.g. a dining nook).
When making crawlspace french drain, is it better for the drain to follow
the foundation wall including all the nooks and crannies, or is it better to
keep the drain straight, i.e. make a large rectangle that fit inside the
Two contractors proposed different approaches, and I wonder which one is
better. The water is believed to come from the ground during rainy season
(i.e. rise in waterbed), although this is not proven. The other possibility
is leaky downspount drain lines.
Also, the sump pump will soak in water in a drain bucket at all time. Even
though sump pump are designed to sit in water, I think they still last
longer out of water. Would it be better to put a tiny hole at the bottom of
the drain bucket, so that large amount of water still get pumped out, but
standing water (below the water level switch) will gradually drain out and
leave the pump dry?
The reason I believe the pumps last longer when dry, is because I once left
a sump pump in a hottub for several years. When I pulled it out, all the
fasteners (screws) have become rusty.
