Most PEX pipes are rated at up to 160 PSI burst rating depending on temperature. There may be other manufacturers of PEX, but I was recommended to use Rehau brand PEX A by a guy with our local water company because he said it was hands down the best PEX brand and it is rated up to 200 PSI. He said Rehau PEX is the only PEX used by many county and city water companies in the state of Alabama. I'm no expert. Just passing on what I was told. Rehau PEX A is available at our local plumbing supply company for 10 cents a foot more than other PEX A brands like Apollo.

My plumbing supply company has rolls of flexible PEX A up to 600' long for 3/4" or up to 500' long for 1"PEX regardless of brand. They also have Rehau PEX A in 20' stiff pipes that I will be using inside. I had always thought that PEX C was the only PEX that was in the stiff 20' lengths.

I enjoy soldering because it takes skill to make it look plumb, level, and neat.
Shark bite and pex is like a cheat code, but I still use them.
The Pro press gun and fittings are a God send especially if the water isn’t all the way turned off.

OK, another PEX question.

Going with Pex-B Should I go with 1/2" or 3/4" inch for a bathroom, also will be routing a Pex line to the washing machine.

Once again, TIA

Same here. In fact, I used cast iron instead of pvc for all my drains and vents. People just don't know.

In general, run 1/2" and 3/4" pipe inside a house. 3/4" main lines and 1/2" final lines from the main branch lines to each appliance, toilet, sink, etc.

For very large houses with many bathrooms, more than one kitchen, etc. you could run 1" lines for the main line across the house then branching off to 3/4" pipes and only using 1/2" pipes as the final pipe to each individual appliance, toilet, sink, shower, etc.

Here's a good video on YouTube...

In commercial plumbing 1/2 feeds 2 fixtures, 3/4 feeds 5. I've seen an entire floor of a building ran off of 3/4 (which would never fly today between inspectors/enginerds) work just fine. Use a 3/4 x 1/2 tee to feed your first fixture then a 3/4 x 1/2 x 1/2 should be plenty for the rest.
