I am installing a humidifier in my house, and I need to tap into the water
line. My builder used PEX plumbing and, of course, I don't have any of
the
crimping tools necessary for working on PEX. But, there is a length 3/4"
copper pipe that goes between my water heater intake and the main PEX
water
line above. The total length of this copper is only about 2 or 3 feet. I
would like to solder in a tap for the humidfier connection into this
copper
section, but I am concerned about the PEX that this pipe is connected to.
Does anyone know how far I have to be away from the PEX connection before
I
can safely sweat a fitting into the copper pipe? If I just wrap a wet
towel
near the PEX connection (between the crimp and the joint to be soldered),
will this be an adequate heat sink to avoid damage to it?

Thanks in advance for any advice.

I am going to ask YOU a question.
I just saw that PEX being installed on one of the TV home improvement
shows. I can see that the tools are probably costly. But my question
is this.
Is that stuff solidly installable. In other words, does it sag
between hangers? Can it be used on HOT water? Is there any advantage
over PVC pipe?

Personally, I was not highly impressed with what I saw. The stuff
looks flimsy, probably has a relatively short life expectancy, and
seems easy to damage. Not to mention the need for special tools. It
also appears that the fittings can not be taken apart. Just
curious....

Personally I will only use metallic pipe as in copper, or galv. steel.
I dont care for house floods, and expect my plumbing to last at least
30 years. I have never been impressed with PVC for water supply
either (it's great for drainage and sewer). But the PEX looks even
less durable than PVC.


Like you, I'm also an old fart .

However, you need to get with the program.

Google up Wirsbo and check out their "WRITTEN" 25 year warranty on AquaPex.
Ever try and get a copper pipe or fitting mfg., to cover a defective piece?
Forget about it.

If you are indeed an old fart, 25 years is long enough. If the special tool
"an expander" is
too pricey at about $125.00, consider using another new fitting called a
Shark Bite from
Cash Acme.

Those two items alone will make your life a lot easier, I know they have
mine.
