Some issues were found during the inspection I completed this morning which
I want to call to your attention.
1. The septic tank outlet tee is not centered inside the manhole as
required. However, the effluent filter is accessible and the tank is
already filled with sewage so I do not think it is critical to have this
fixed
2. The pump used is not the one specified on the design plan. The
designer needs to examine the pump, determine if it is appropriate, and
provide specifications and calculations to show it is acceptable (if that is
what he so determines). Alternatively, the designer may require the
original pump that was specified to be used.
3. The floats were not set as specified per the approved plan. The
installer was going to adjust them. The designer needs to examine these to
confirm if they have been properly adjusted and confirm if this is the case
or else provide documentation of the acceptability of the new settings
including relevant calculations
4. The leach field piping is not uniform for all 4 arms of the field.
The do all pitch from the distribution box, and they do all pitch from one
end to the other, however they are at different heights with respect to each
other. The designer needs to examine this and either require them to be
adjusted or else specify the as-built elevations for all 4 arms of the leach
field. The as-built plan that was provided only gives the elevations of the
leach field piping for one arm.
I have discussed this with the installer. He indicated he would be
reviewing this with the designer. You may wish to do so as well. Feel free
to forward this email if you wish.
If you have the Construction Inspection Form started please do send that
along, otherwise I will start one.
Thanks
