One interesting thing about pex is it can't be left in the sun, even when you have a roll of it ready to install. The UV in sunlight will degrade it and cause failures.

FYI, you can rent the press tools reasonably cheaply if you’re not a plumber by trade. I rented one for $80 for a plumbing project a few years back and it was worth every penny. A million times easier & faster than sweating joints.

Yes! I saw a youtube video and of course, it had me believing I needed to own this tool even though I'm not a plumber.

>Many Florida residents have their second set of pipes running through their attics

When/if I remodel my bathrooms I have to have this done due to my existing galvanized steel pipes being horrendously brittle and filled with 70 years of gunk. Ah, the joys of a house built in the 1950s in Florida.

For me it was the waste lines giving me trouble. The drain lines for a tub in a house built in 1962. The size of the inlet meant I wasn't finding a drain at Home Depot.
