I'm curious as to whether the probability of a plumbing leak increases
in a straight line, or exponentially as the water pressure increases.
Can anyone clear up this mystery for me?
Thanks in advance
Most types of leaks (hotwater heater excepted) change only in degree
with pressure. Low pressure will not reduce leaks, only make them leak
High pressure can break out weak points and things like washer hoses,
but for the most part, pressure has little to do with the number lf leaks.
Thanks for your courteous reply.
I'm not sure I made myself clear. I'm looking to find out whether the
likelihood of a leak increases in direct proportion to an increase in
pressure (ie. if the pressure is increased by 20%, does the
probability of a leak increase by 20%, or does the probability
increase by a greater amount as the pressure approaches the burst
point of the pipe)?

Likelihood of a leak probably increases in _less_ than direct proportion
to an increase in pressure until you start getting close to burst point.
Likelihood of leaks is far more dependent on other factors - such as
corrosion effects, poor workmanship and defective/damaged materials.
While increased pressure will accelerate the occurance of leaks, unless
you have the other factors, it's going to make very little difference
until you start getting close to the burst point.
[Burst point being defined as the burst strength of the weakest part of the
system - eg: poor joints, physically damaged pipe, etc.]
