Brian, Steve, Toni -
Attached please find the findings of our inspection at 469 Boston Street.
There were some unresolved issues which will need to be re-examined. You can likely do so at the final grade inspection,
or we can do so if you'd like. They are noted on the report and also explained below:
• The distribution box did not have hydraulic cement at the pipe penetrations
• There was not enough water in the pump chamber to confirm the operation of the pump
• There was not even flow coming out of the distribution box to the three arms of the leach field. The branch closest to
the dwelling was not receiving much of any flow. They reported they were going to either adjust the pipes or d-box, or
else put in leveling devised inside the pipe. I asked them if they did the latter to check to make sure they have not
restricted the flow to the field when the pump turned on
The contractor was going to leave the distribution box area uncovered so these items can be reviewed at the final grade
inspection.
Any questions, do let me know.
Dan

To whom it may concern,
I, Matt Quinlan, Owner of 469 Boston St. have requested that Simard Construction loom and
