Getting back to this thread;
This is an unusual thread for this list in that, after being initiated by
Brett's tirade and who then apparently backed away from it, no one excepting
a lurker has been willing to touch it with a 10' pole!  I hate being the
only one that's right and willing to speak up!

Further, I am always suspect of anyone that feels compelled to spend a half
page in justification of his unquestionable expertise and experience and
then must resort to personal attack rather than to fact and logic to justify
his position.

No bias on Tim's part, he was just defending his government mandated
livehood as a hired wrench!  Does a conflict of interest exist when the
State inspector is also the hired wrench?  Another good reason for not
residing in the "Umpire State".

Sure, there is little harm done when all hoses are replaced because of a
superficial crack in the abrasion protection, at least once past the DOA and
infant mortality reliability issues of any new component.  Most industrial
hydraulic hoses that utilize an extruded abrasion protection outer layer are
perforated along the entire length of this material during manufacture such
that, if the pressure conduit leaks, the outer layer will also leak and not
balloon, thus destroying its only purpose, abrasion protection.

But most disturbing to me is his strong put down of the frequent proof
pressure testing of the complete hydraulic system in preference to his
superficial visual inspection of just a few system components, at the
government's mandated annual or biennial intervals.  An invite to
complacency, "not to worry, the government is looking out for me".

FACT: There is no better way to guard against catastrophic failure and
guarantee the leak free performance of any hydraulic system than to proof
pressure test it at pressures several times the maximum system working
pressure and at frequent intervals, always monitoring for leaks.  Get the
habit, guys!
