MAINE JOURNEYMAN PLUMBING EXAM WITH ACCURATE SOLUTIONS ALREADY
GRADED A+
Rainwater is hard or soft?
Softwater (Contains few minerals)
Name for layer of saturated ground
Water Table
Dug Well depth
20'
Driven Well
A well constructed by driving a pipe in the
ground. The drive pipe is usually fitted with a well point
and screen. 60' maximum and for sandy, loose areas
Drilled Well
Deep well designed to tap the lower aquifer; can be up to 1,000 feet deep with a small cap
above ground; less susceptible to pollution. It is also cased.
Shallow-well pump depth
,25' to 35'
Purpose of Pressure Switch
Turns pump on at 20 psi and off at 40 psi
Venturi
narrow opening in the jet body of pump to create a low pressure
PSI requirement to raise a column of water 1 foot
.434 psi (stories are usually 10' tall)
Average water pressure
14.7 psi
Reduced Pressure Zone Valve (RPZ)
Installed inline; serves an entire building or specific zones of a piping system
Dual Check Valve
Has two spring-loaded check assemblies manufactured as a single device. Used mostly to
serve a single piece of equipment, such as a commercial ice machine
,Atmospheric Relief Valve
Installed to serve one piece of equipment, spills water trying to backflow that will
depressurize the system to atmospheric pressure
Vacuum Breaker
Breaks a vacuum in a piping system by introducing air into the pipe
Water Service area
Portion of piping outside a building
Water Distribution System
Piping within a building
Pressure-reducing valve
installed after main isolation valve when water pressures exceed maximum limit
Two trenches required distance apart
5' of undisturbed soil between two systems
, Elongated Toilets are for Residential or Commercial?
Commercial
Round Toilets are for Residential or Commercial?
Residential
Two Flushing Ways for Toilet
Siphon Jet (Residential), Blowout (Commercial)
Distance Req. Center of Toilet to back wall
12" (10" to 14" special orders)
Pop-up Lavatory: Res. or Comm.?
Residential
Grid Strainer Lavatory: Res or Comm.?
Commercial
Lavatory Faucets of 3 hole designs necessary inch spread?
4" spread of two outside holes
