[C320-list] Fresh water head-flush plumbing

Possibly, but Pepsi also contains a fair bit of phosphoric acid.  The
goal of using Pepsi was probably to dissolve the lime deposits with the
acid.  However, calcium phosphate has a solubility of 0.002 g / 100 g
of water, so pepsi would probably serve to harden the lime deposits,
not remove them.

Vinegar (as recommended by Peggie Hall and others) should serve to keep
your drains free running and sanitary.
