Exactly the type of valve I was talking about installing. $9 at Home Depot.
After sorting through all the responses, I think I'll just go ahead and cut
the pvc pipe on the backup and install one.
no one mentioned the obvious, sump pumps should never drain to a
sewer. in heavy rains it can cause flooding not only of your basement
but the sewer lines in the neighborhood and sewer plant..... too many
such connections..... equals flood:(
having seen first hand sewer water gushing up out of a basement floor
drain its no fun....
if the sump pumps check valve sticks open under heavy rain the sewer
crud could fill and contaminate your interior french drain:( might
require digging it up to replace it:(
everyone with a sump pump should check to see if theres ANY WAY to
drain the sump to daylight! far too many people want to avoid digging
and install a pump when just a drain line would work fine
