PEX version
I had to do this to all the lines in my house when I bought it. Replaced everything with pex lines with a snazzy manifold to equalize pressure. Did it myself and spent about $600-700.
This is the manifold I bought. https://www.amazon.ca/dp/B008J33N5E
Your intake line problem sounds kinda different but thought I would share anyway. Good luck!
$150 bux on amazon, I used a Manabloc, the only thing I didn't like was that I had to use crimp connections instead of ProPEX like the rest of my plumbing, but that's a minor complaint I guess.
