e) Is independent of pipe wall smoothness
2) Excess water pressure may lead to -
a) Excess water velocity
b) Excess friction loss
c) Longer operating periods for dishwashers
d) Longer operating periods for clothes washers
e) Sklashing and excessive siphoning as toilets are flushed
3) Causes of poor pressure and flow in a house include all of the following except -
a) Undersized piping
b) Rusted piping
c) A gate valve type main valve

d) 6 inches in diameter
e) 12 inches in diameter
5) Which of the following is not a cause for an inoperative pump?
a) The motor is burned out.
b) The discharge line is split.
c) The control switch for the pump is not working.
d) The thermal overload has tripped.
e) There is no electricity at the pump.
Damn. Gonna have to go with E, as a really weak one. The tank valve may be leaking because of the pressure, but that won’t affect gravity flush. If the pressure is too high “Sklashing” maybe is the sound of too much water jetting in for the bowl rinse, resulting in a too strong a siphon down low.
C (so going with C as the non-problem, as it would take a hell of a leak, more like a flood, to affect pressure much)
C (typical depth limit based on local conditions of course)
B
