Connecticut (CT) J-2 Journeyperson Water Pump &
Conditioning Exam | Latest Verified Questions and
Detailed Answers
OVERVIEW DESCRIPTION:
This Comprehensive set of multiple choice questions is designed for the CT J-2
Journeyperson Water Pump & Conditioning Exam, a closed-book, timed assessment
administered by PSI Exams. The content addresses well pump mechanics and types, water
treatment and conditioning, piping systems, pressure control, hydraulic principles and
math, and safety and code compliance, evaluating a candidate’s readiness to troubleshoot,
install, and maintain residential and small commercial water systems in accordance with
Connecticut regulations.
QUESTION 1
What is the primary purpose of a foot valve installed at the bottom of a suction pipe in a
shallow well jet pump system?
A) Prevent debris from entering the pump
B) Maintain pump prime by holding water in the suction line
C) Increase suction pressure
D) Reduce water hammer
CORRECT ANSWER: B
EXPERT RATIONALE: A foot valve is a check valve at the inlet of the suction pipe that
keeps the water column intact, preventing loss of prime when the pump stops.
QUESTION 2
According to Connecticut regulations, what is the minimum horizontal separation
between a drilled well and a septic tank?
A) 25 feet
B) 50 feet
,2|Page
C) 75 feet
D) 100 feet
CORRECT ANSWER: C
EXPERT RATIONALE: Connecticut Public Health Code requires at least 75 feet separation
between a well and a septic tank to protect groundwater from contamination.
QUESTION 3
A bladder-type pressure tank has a pre-charge air pressure of 18 psi. The pump cut-in
pressure is set to 20 psi. What pre-charge should be used for proper operation?
A) 18 psi
B) 20 psi
C) 22 psi
D) 16 psi
CORRECT ANSWER: A
EXPERT RATIONALE: The pre-charge should be 2 psi below the cut-in pressure; 18 psi is
correct for a 20 psi cut-in.
QUESTION 4
Which type of pump is most commonly used for deep wells (over 150 feet) in residential
applications?
A) Shallow well jet pump
B) Deep well jet pump with a two-pipe ejector
C) Submersible multi-stage pump
D) Regenerative turbine pump
CORRECT ANSWER: C
,3|Page
EXPERT RATIONALE: Submersible multi-stage pumps push water from depth efficiently
and are the standard for deep wells; jet pumps lose efficiency below about 120 feet.
QUESTION 5
A water softener resin tank contains 1.5 cubic feet of standard 8% crosslinked cation
resin. What is the typical maximum exchange capacity if the resin is rated at 30,000
grains per cubic foot?
A) 20,000 grains
B) 30,000 grains
C) 45,000 grains
D) 60,000 grains
CORRECT ANSWER: C
EXPERT RATIONALE: Capacity = resin volume × grain rating = 1.5 ft³ × 30,000 grains/ft³
= 45,000 grains maximum under ideal salt dosage.
QUESTION 6
When calculating Total Dynamic Head (TDH) for a submersible pump, which head
component is the vertical distance from the pumping water level in the well to the point
of use?
A) Friction head
B) Pressure head
C) Static lift
D) Velocity head
CORRECT ANSWER: C
EXPERT RATIONALE: Static lift is the elevation difference from the water level to the
discharge point; it is the primary vertical head component of TDH.

QUESTION 7
A pump delivers 15 GPM against a TDH of 200 feet. What is the water horsepower
(WHP) delivered? (Use WHP = (GPM × TDH) / 3960)
A) 0.57 HP
B) 0.76 HP
C) 1.14 HP
D) 1.52 HP
CORRECT ANSWER: B
EXPERT RATIONALE: WHP = (15 × 200) / 3960 = ≈ 0.758 HP, which rounds
to 0.76 HP.
QUESTION 8
Which plumbing material is prohibited by the Connecticut plumbing code for use as
buried well drop pipe in potable water systems?
A) Stainless steel
B) PVC Schedule 80
C) Galvanized steel
D) High-density polyethylene (HDPE)
CORRECT ANSWER: C
EXPERT RATIONALE: Galvanized steel is subject to corrosion and zinc leaching; code
restricts its use for potable water piping, favoring corrosion-resistant materials.
QUESTION 9
A residential reverse osmosis unit uses a 50 GPD membrane rated at 60 psi feed
pressure and 77°F. If the inlet water temperature drops to 50°F, what happens to the
permeate flow rate?
A) It increases by about 20%
