1. 1. A 12‑story mixed‑use building will be supplied from C
a municipal main at 65 psi static. The top fixture is 135
feet above the meter and the design residual at the
top fixture is 15 psi. Ignoring friction for a first‑pass
check, what is the most reasonable design action?
A Add a single booster pump sized for 50 gpm at 30
psi
B Rely on city pressure with oversized mains
C Provide a booster system with at least one PRV‑-
zoned discharge header D Add PRVs only at the upper
floors
2. 2. You are selecting the diameter of a domestic cold B
water service using a fixture‑unit/peaking method.
The facility has highly intermittent, diversified loads.
Which design approach best reflects ASPE practice?
A Size strictly by connected load without peaking
B Use fixture units with a probabilistic peak flow curve
and check velocities C Use only the largest simultane-
ous gang restroom as the basis
D Base solely on meter size furnished by utility
3. 3. A vertical sanitary stack in a high‑rise needs a C
mid‑building horizontal offset around floor 16. What is
the primary hydraulic concern driving your detailing?
A Thermal expansion at the offset elbow
B Solids deposition due to reduced slope
C Positive/negative pressure transients and relief
venting across the offset D Condensation on pipe ex-
terior

4. A hot water recirculation loop is failing to maintain
temperature at distal branches overnight. Pump is
running continuously. What is the most likely systemic
cause?
A Recirc pump oversized
B Return mains oversized and branches unbalanced
C Source mixing valve set too high
D Insulation too thick
5. 5. A roof uses controlled‑flow primary drains with B
overflow scuppers. During commissioning, ponding
reaches the structural live‑load limit before overflow
operates. Which is the most appropriate corrective
action?
A Increase overflow weir elevation
B Enlarge orifice plates in primaries to reduce ponding
rate
C Reduce primary strainer open area
D Remove orifices from primaries
6. 6. For a duplex sewage ejector serving a basement re- A
stroom group, what is the most critical control feature
to verify for reliability?
A Alternation of lead/lag with independent thermal
protection
B Single float switch for both pumps
C Manual start only
D Normally open check valves
7. 7. When reviewing pump curves, a designer notes B
the system curve shift after adding balancing valves.
Where does the pump operating point move?

A Up and right to higher flow and head
B Down and left to lower flow and higher head
C Horizontally right to higher flow, same head
D Vertically down to lower head only
8. 8. A central heat‑pump water heater (HPWH) will be C
installed in a conditioned mechanical room. What co-
ordination issue is most important early in design?
A Copper vs. CPVC on DHW
B Return loop temperature sensor brand
C Room heat extraction and makeup air/ducting strat-
egy
D Aquastat setpoint calibration
9. 9. A lab tenant improvement includes acid waste from C
three sinks to the building sanitary. Which baseline
solution aligns with ASPE guidance?
A Schedule 40 PVC directly to sanitary
B No‑hub cast iron to sanitary
C PP or PVDF acid‑resistant piping to an in‑line or tank
neutralization system before sanitary
D Galvanized steel with epoxy liner
10. 10. In a high‑rise domestic water system with three B
PRV zones, field reports show pressure creep at night-
time. What's the first best step?
A Replace all PRVs with larger sizes
B Verify PRV downstream isolation/checks and inspect
for debris or seat wear
C Lower the building setpoint globally
D Increase pump VFD minimum speed
