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

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,

Ha. If this is the worst thing they could find wrong with your house
I'd tell 'em to go pound sand.
