Plumbing Comments:
Sheet P2.0
a) The 6" RD piping from area drains (exterior of building) have been rerouted to sump
pump SP-4 to provide necessary elevation lift so it can be terminated in the storm water
detention vault at the correct height.
b) The plumbing fixtures on the parking level were rerouted to sump pump SP-3, because
the vertical drop was not adequate as designed. The sump pump will discharge to the 8"
sewer exiting the building at the Trash Room.
c) The previous parking lot drain was changed to sump pump SP-2, to provide adequate
elevation to connect to the sand and oil interceptor SO1-1 in the Trash Room.
2. Sheet P3.0, and P6.1
a. Water meters were added to the Hot Water lines in the Boiler room. One meter will
serve the commercial kitchen and one meter will serve the resident's hot water.
3. Sheet P3.2, P3.5, and P6.3
a. The hot water distribution loops, for the resident's hot water supply, was changed.
Previously there was a HW distribution loop on the 2nd floor, serving floors 2 and 3, and
there was a HW distribution loop on the 51h floor, serving floors 4, 5, and 6. This did not
comply with WSEC hot water distance to a fixture, so the design has been changed to
provide hot water risers at each fixture to reduce the piping distance to the fixture. The

hot water distribution list on the 5t" floor has been changed to a hot water recirculation
loop, where the hot water risers terminate at flow control devices. The hot water in the
loop is then routed back down to the Boiler room. See revised Hot Water riser diagrams
on sheet P6.3 for sizing and detail.
