If raising the water level doesn't fix it, I'll ask you again.

Makes no sense to me. Raising the water level in the sump won't help unless it is raised above the level of the French drain--in which case the water will simply accumulate in the French drain. If "x" gallons per day go into the sump, "x" have to be pumped out, whether the maximum level in the sump is 20" or 24".
