Seeking advice for sump pump drain pipe
|

| Our 1960 split level has a sump pump in the basement that kicks on 5-10
times per day (we live in upstate NY in a region with clay soil and a
high water table). When we first moved in, the sump drained directly
into the main house drain and out to the sewer (a no-no in most
municipalities). We corrected this and the sump now drains out to the
back yard (approx 20ft from the house).
I would like to bury the drain pipe and have it run 30+ ft away from
the house. However, I'm not sure how deep to bury the pipe.
Our frost line is quite deep here (42", I believe - again, upstate NY).
But, since this is a drain pipe (that should be empty unless the pump
is actually running), do I need to go that deep? Can I get away with,
say, 2 feet?

well, if you use a 4'' pipe i don't see the need to go down lower than
a foot. give it a good incline (min 1/4'' per foot) and put your
digging energy into a big drywell.

I'm in upstate NY with clay soil - two feet is fine if there's a decent pitch
downward. When I had that done, I had drainage put in as well (french drain
with another pipe, perforated) and had it run all the way back to a drainage
ditch behind my property. They put a PVC grate on the end of the sump drainage
to prevent critters from making the return trip. Works well.
