Is it possible to hook up a bathroom sink to 2 partially inch pvc shutoffs?

Different between sand sealer and primer sealer ?
Answers:    The standard "IS" 1/2 inch inlets for a bathroom sink. The only flux in the logistics and set up would be if your sink faucet is a single knob unit. The two inlets, H & C would consequently be connected with the proper hardware/plumbing.
Has anyone built near ICF?
Yes, they market adaptors to either trim down or increase the pipe size to the size you need. (About 78 cents any at the plumbing supply store or Home Depot or Lowes.)
