Mouth PEX flow trick

[Slomoola]

Build a 12", 1/2" PEX A pipe with PEX A fittings on each end. Build the same PEX B test pipe, fittings on each end. Now blow with your mouth through both.

Then wonder why PEX B is still on the market. If you use 90 degree elbows it's even worse.

I don't have any Type A fittings but the pipe is the same whether A or B. Fittings appear the same but I don't have any A handy as I don't have an expander.

Properly sizing a water system requires understanding the flow of whatever piping system you use.

And the vast majority would never "notice" the difference.
