I’m going to change the countertops soon so I wasn’t super concientious about the caulking job.
I was a little pissy about the fact that the hold downs seem like they were designed by morons that don’t understand Newtons 3rd law, because when you tighten them, they just rotate until they’re hard against the sink wall. And the tap still uses a nut that needs a huge basin wrench instead of what I’ve seen on other taps like a nut that tightens by hand and then you just use a Philips screwdriver to tighten a couple machine screws that finish the job.
Ah well, it’s in and I get to do it all over again when I order countertops.
The most common mistake people make with this is forgetting to waterproof the edges of the hole in the counter. Then if there’s no proper seal between the sink and the countertop, water eventually seeps underneath and bloats the whole thing.
