#1 Are those supply line PVC or CPVC. Againt code to use PVC for anything except drain lines.
No way do you need any more then 1" line as a main run. Most home are done with 3/4" and work just fine.
Unless your running a rooming house with 10 bathrooms forget about changing it to 2".
That's on funky plumbing job with all those elbows, but that not what's causing the problum.
Did you remove the aireators on the faucets and shower head to see if there pluged up?
