Common salt would not affect the #pH# of water to any extent.....

Explanation:

#NaCl(s) stackrel(H_2O)rarrNa^(+) + Cl^(-)#

Neither sodium ion nor chloride ion effects water hydrolysis.

There are of course other salts, for instance, sodium fluoride, that would lead to hydrolysis:

#NaF(aq) +H_2O(l) rightleftharpoonsHF(aq) + HO^-#
