He told you wrong. Heat is never used.

He has been in the business all his life. He keeps his tools hanging at
the store because he has several houses and never knows when a tenant
may have a plumbing emergency. He knows plumbers but it's been so long
since he needed one, that he doesn't know what they charge these days.

People can buy plumbing supplies cheaper at big stores, but he does a
thriving business because he'll give them advice they can count on.
I'll take his word over yours.


If I have to replace any more tubing, I want to use PEX. How do I slide
it on to a compression fitting designed for PEX and polybutylene? Is
heat the best way? Would a hair dryer be my best source? Would a
different brand of fitting solve the problem? Would faucet grease do
the trick?

No, not exactly.

Learn how to install PEX on a pipe stub out.

What kind of fittings did you use in your very limited experience? You
are no doubt aware that Flair-It is different from other compression
fittings. They are certified for homes but were developed for motor
homes, boats, and mobile homes, where vibration and movement could could
nuts to come loose.

I was not aware of the difference until I found videos of company
representatives showing how to push on PEX. As the instructions say,
they used a rocking motion. So did I. They also used white-knuckle
pressure, as did I, but I couldn't force mine on. I suspect they'd
warmed their tubing to be sure the demonstration worked.

The O at the start of your name will always remind me of a very large
mouth. Why is it that those with the biggest mouths are so often the
most ignorant?


I replaced a bad section of pipe about a year ago and used PEX and those
"Sharkbite" fittings...the PEX pushed right in.


So that's a brand that works. Why did you tell Oren and not me?

Are you aware that Sharkbite push-to-connect fittings are entirely
different from other compression fittings? The insert is there only to
be sure the tubing doesn't collapse.

The clerk is an idiot and if the stuff does not push right in he must
have sold you something defective.


Is "philo" short for "philosopher?" Here's a bit of philosophy for you.
We often have low opinions of others because we wrongly assume they
are like ourselves.

Are you and Oren spending the weekend drinking together? Is it the
liquor that makes you talk that way, or do you drink to excuse such
behavior?
