Step 1. Determine design pressure to building. Use minimum pressure at meter plus or minus elevation at 0.5 psi per foot difference.

Min press – (0.5 x Ft. above) = __________________________________

Min press + (0.5 x Ft. below) = __________________________________

Step 2. Table 610.3 Determine the number of Cold / Hot Water WSFU for the system.

TABLE 610.3 WATER SUPPLY FIXTURE UNITS (WSFU)

Fixture Type Fixtures Cold WSFU Total WSFU - Cold Hot WSFU Total WSFU Hot

Bath

Tub / Shower 4.0 4.0

Shower 2.0 2.0

Laundry sink 1.5 1.5

Clothes washer 4.0 4.0

Kitchen

Kitchen sink 1.5 1.5

Dish washer 1.5* 1.5

Hose Bibb 2.5 __________

Hose Bibb - Add. 1.0 __________

Totals

Important: Total System WSFU = Total Cold Water WSFU plus dishwasher WFSU

Branch 1 Cold WSFU = ___________________________________ = ____________

Hot WSFU = ___________________________________ = ____________

Branch 2 Cold WSFU = ___________________________________ = ____________

Hot WSFU = ___________________________________ = ____________

Branch 3 Cold WSFU = ___________________________________ = ____________

Hot WSFU = ___________________________________ = ____________

Branch 4 Cold WSFU = ___________________________________ = ____________

Hot WSFU = ___________________________________ = ____________

Total System Demand: Total of Branch 1 + 2 + 3 + 4 = ________________________________


12

Step 3. Determine the Hot Water demand for system. This will be used in Step 8 to size the branch line to the water heater. Hot water system demand = total of hot water WSFUs from each branch.

Branch 1 – total of hot water WSFU = ___________________________________= ____________




Total Hot Water Demand = Total of Branch 1 + 2 + 3 + 4 hot WSFU = ______________________

Step 4. Determine longest run of pipe to the remote outlet. (From Meter Base) Branch 1: Length of Cold: ____________________________________________ = ____________

Length of Hot: _____________________________________________ = ____________

Branch 2: Length of Cold: ___________________________________________= ____________

Length of Hot: ____________________________________________ = ____________


Length of Hot: ____________________________________________ = ____________


Length of Hot: ____________________________________________ = ____________

Longest run to remote outlet is __________ ft. (Branch _______ Cold / Hot)

Step 5. Determine the pressure range rows and column for the longest run. Use Table 610.4 Always round up to the next vertical column of run of pipe to the remote outlet. Pressure range on Table 610.4 use: (cycle one) 30-45 psi 46–60 psi Over 60 psi Max allowable length column use: (cycle one) 40 60 80 100 150 200 250 300 400 500 600 700

Step 6. Size supply to meter and to building. Use Table 610.4 Read down to column until the minimum number of fixtures that were determined in Step 2 is found. Read Minimum Size Supply to Meter and to Building from far left column of table. Use: Meter size 3/4 Building Supply size 3/4 1 11/4 Use: Meter size 1 Building Supply size 1 11/4 11/2 2 Use: Meter size 1 1/2 Building Supply size 11/4 11/2 2 Use: Meter size 2 Building Supply size 11/2 2 2 ½

Step 7. Sizing branches.


13

Calculate branch demand WSFU for both the cold and hot water. Longest run to remote Outlet from Step 4 and the appropriate pressure rows, read down the column to the total WSFU for that branch. The far left column will show the minimum branch size. Note that the branch size does NOT need to be larger than the building service size. Branch 1: ______ (cold water WSFU) + _____ (hot water WSFU) =_____ total: _____” size

Branch 2: ______ (cold water WSFU) + _____ (hot water WSFU) =_____ total: _____” size



Step 8. Size supply ONLY to water heater. Size the pipe to Water Heater using Total Hot Water WSFU from Step 3. Total system hot water WSFU = ________ total: _______ “size
