Hello.

I'm in the process of redoing my kitchen and a friend suggested Wirsbo
Aquapex. I am fluent in using copper but decided to use Pex since it
is easier.

The PEX was installed about 4 weeks ago and has been exposed inside my
kitchen, which has a large window and a skylight. Typically the
window is partially covered, but the skylight lets in a lot of light.
The PEX has been "exposed' to UV from the window and skylight for over
30 days, but seems to be holding up fine.

I have just become aware of the UV exposure issues with PEX.

I am ready to sheetrock the kitchen in a week or so but now have
concerns about the UV exposure of the piping and do not want to have a
failure later on down the line.

Anyone have any thoughts? Do I need to rip it all out?

It takes YEARS for UV to affect it. Relax, no harm done.

Don't worry about it. I would cover it up, but it won't rupture or burst
unless it sat exposed for a few months/years.

I cover all my PEX lines with those black foam insulation pipe things not
for the insulation but to keep them out of the sun.

Sounds like you already knew the answer to your question before you asked
it.

I would not be concerned.

I live in the desert and during new construction PEX is exposed for
periods of time; waiting for inspections.

From my Vanguard material:

DO NOT INSTALL WHERE EXPOSED TO DIRECT OR INDIRECT SUNLIGHT FOR MORE
THAN 60 DAYS. PEX tubing shall be stored under cover, shielded from
direct and indirect sunlight when the material is stored for any
length of time. Short exposure times, not exceeding a total
accumulated time of 60 days maximum, are permissible.

Take a couple of scraps of pex and sit them out in the sun. Check them
every week. See just how long it will take to get any stiffening or
cracking from UV. Four weeks is nothing, four years, maybe. This is not
something that is damaged in a short time. Don't take my word, test some.

That's a good idea. I have a scrap piece that has been laying outside
in my "spare" pile for a while. Maybe I will hook it up and see if it
holds.
