Finding Polybutylene (PB) pipe

Found a small section of PB pipe in my house ... supply to the dishwasher.  The dishwasher sprung a leak, and I decided to replace it rather than fix it.  

Researched PB pipe and found out:

1) it's mostly the chlorine and UV that caused the problem.
2) I have a well, so no chlorine
3) the only PB pipe is under the counter, so no UV
4) thus, I can leave it if I want.
5) Even though PB fittings "seem" to work with pipe thread, the thread pitch is different.
6) I left the PB connection to the water lines in place and just used the PB pipe, about 8 inches, as a stub out.
7) Slide on a SharkBite U4008LFA fitting on the PB side

So, continuing on ... 

8) On other side of fitting, installed a 1/2" PEX line (SharkBite U860R2)about 12" long
9) On the 12" PEX, installed a BrassCraft model G2PS14XC1 valve with a 3/8" compression on other end, which then goes to the dishwasher line.
10) And as most surely know, dishwashers use a garden hose connection, so you use a dishwasher connection kit with the elbow and 3/8" hose you need.
