Peggie,

This one will be a little tough. Yes, I did try pumping longer in fact
for a very long time, it didn't even improve a little bit.

Weeelll...it was an idea.

I am leary about adding a one-way. Will adding a one-way valave just
after the sump really be a solution, or just delay the water coming
back into the sump by another 30 minutes or so?

My thought was, it would allow the pump to retain prime long enough to
pump the rest of the water out the line...but it would also prob'ly get
clogged up, so it wasn't the best idea I ever had.

p.s. Your book was great !

Thanks!
