I'm selling my house, and the home inspector pointed out that the

easy solution??

It's been working for me for the last 4 years (despite the occasional
gurgle), and don't think it's been any different since construction in
1980... I sure don't want to do a major remodeling just to make this
sale.

Thanks,

There are code-approved under-sink vents (vacuum breakers) you can add
to the drain line. Go to any good home store and they will sell you one.
