Hi, Joanne. I have revised these plans in response to your email on Dec 16. 1 hope we
can get this approved. I think there is plenty of information to install this grinder pump.
Highlights of revisions follow. See plans which I highlighted for reference.
® C2.0:
o Notes added about concrete anti -float base
o Reference note to new diagram on C3.2 added
o The side sewer is installed at 2% per chat with Todd. Note revised to 2%
o "or equal" removed as requested in your email
0 36" depth requirement is called out on C2.0 in a few places and on C3.2
® C3.2
o New diagram added to upper right of plans that shows relevant info in
profile as requested, including another reference to anti -float concrete
base.
o Inverts shown.
o Please see pump curve with point on curve where Todd's 8 feet of TDH
(total dynamic head) falls which indicates expected flow rates in the 42 to
44 gpm range.
Thanks and hope this is finish line,
Duffy
