Structural strength wood restoration (plumber was an idiot)
 

A plumber, rerouting supply and drain pipes behind a vanity drilled
large holes into a 4x4 supporting beam. Believe me, they are not
trivial holes. We didn't like that idea and will reroute the pipes.
What can we fill the holes with that will have structural strength? We
could nail 2x4's to either side of the beam as well.

Two-part boatbuilders' epoxy (System 3, West System, Mas, or similar) thickened
with wood flour. Get it at West Marine or other marine supply. Stronger than
the wood and similar expansion characteristics. Waterproof, shrink-free, no
noxious fumes; sets in a few hours.

You can use the same stuff to glue the "sistered" boards to the beam, which will
have much more strength than nails alone (probably stronger than the wood
itself).

How big are the holes? How would you install the drains? You're
likely worrying about nothing.

I've used plumber's putty (2 part epoxy in a clay form) for some crude
boat repairs.
