Jim wanted to know...

A couple questions.
Were these *real* sharkbites, or 'sharkbite type'?
Installed at the factory, or during the site install?
Were they in a spot that might be getting some vibration from the
whirlpool?

These are "actual" SharkBites installed at the factory used on 1/4"
poly tubing subject to pump vibration within inches of the sanitizer.
(So they probably lose their grip on the polyethylene)
