I Build homes in Arizona and use 100% PEX in construction. To be honest with you I have never noticed any odor at all from the pipe so my guess is the odor must dissipate. I lived in a house that was PEX as well and did not notice a smell. I imagine it could be different if you are already living in an enclosed home when the PEX is installed, but there are ...

I would say this would be much better than the current surface mount of the pex. It will look better and less chance of damaging the lines.

Pressure loss in a pipe is proportional to the flow through the pipe. A garden hose has potential for high flow, meaning higher pressure loss in the pipe, and you mention that the system pressure is already "not that great." I can think of two reasons not to use a larger-than-necessary pipe: when it simply costs too much to use the oversize pipe (...

I think you should take off for the outside faucet from the 3/4" PEX. This will have a lesser effect on the water pressure inside the house than taking off on the 1/2" line that goes to the kitchen. You can always throttle back at the outside faucet if you need to. EDIT You could run a 1/2" line to the outside faucet, split off from the 3/4&...

1/2" is fine for individual fixtures such as sinks and dishwashers, but high flow fancy showers should be 3/4" Also, your trunk line should have been 3/4". It also depends upon the water pressure supplied by your utility or well. If it's high enough, you can "get by" with 1/2" but bigger is usually better. The only ...
