Attention John Williams
Attached is the cut sheet for the Back Water Valve proposed by the plumbers. Please
review the attachment and let me know if you and the Building Official agree with this
product for Dartmouth Square. It will be installed underground, in the planter between
the south face of the building and the sidewalk. Ample access will be provided. I will fax
a copy of the plumbers method of install later.
Thank you
Larry Brooks
