lavatory faucet install ?

As a bit of a strange gift we were given a new bathroom vanity and vanity top. Installed.

That did not include the faucet or the water lines or drain.

My mobility is not what it was and my husband, who is 6-foot plus, plus, plus has been trying to install the new faucet today.

It's a "single-hole" Delta. The problem is, he has gotten the under sink flange as tight it can go and the faucet atop the marble countertop still moves about.

The space is extremely tight for him and he has given up for the day. Poking about the web, the only thing I saw was trying some emery cloth between the under sink flange and the countertop.

But, that does not make sense, since the under-sink metal part is not moving, it is the atop sink faucet that is moving.

Sunday is a new day and he is determined to get it right by afternoon. Any tips?

In the following video, you will see the problem part starting at the 46-second spot....

The part is about as tight as it goes with the "included wrench>"

I was thinking old bike inner tube between the undersink flange and the bottom of the countertop, but again, it is the top part (faucet) that is moving?

Countertop does not come off without a sledgehammer.

The flange is pretty much as it looks in the video (well, it is actually a different design, but the concept is the same) -- it actually looks like the part below -- #4.

I found one post that said it is a common problem (no solution) and one "help" forum answer from Delta about the emery cloth. And a third post from Delta telling folks to use Silicone to stop from moving, which is a real stupid solution as silicone will not stand up to any sort of torque.

As you can see in the instructions below, part #4 is the part that snugs up under the countertop, held by the nut # 6. Parts 2&3 are the parts on the bottom of the faucet that snug to the top of the countertop. Part 2 is a decorative metal ring. Part 3 is a plastic ring/gasket. Part 5 is the threaded rod that the nut (part 6) threads onto.

And, yes, the faucet is extremely ugly. I was not having my best day when I picked it.

 

Thanks for the replies.

Still without a working faucet. Husband ran into work problems overnight and ended up going into the office and then coming back home and sleeping the afternoon away.

Any tips are still appreciated.

Bisco:

I am challenged on movement lately. Husband is still asleep. Not sure what is going on with the amount of tightening left. I found that Ridgid makes a new sort of basin wrench that I would not mind owningl

We will have to see....I suspect this will be a week of "yeek" and then a simple solution in the end.

Husband Kevin ended up with the afternoon off. He tackled the faucet from H*** again. This time with thin rubber washers/gaskets both above and below the sink.

Success. No movement. However, the vanity top leaks slightly, but is still usable. Those folks will be out to fix that on Tuesday.

So, 95 percent good!

Nice, since have been without use of the master bath sink since February.

Oh, the drain was clogged after we got it all set up also, but a quick run of the closet auger fixed that.

The countertop is cultured marble.

When we filled the sink to the top to check for drainage and leaks, there were two small drips under the countertop, just under the overflow, which of course was being tested when we filled the sink to the brim.

so, when crafting, some air bubbles developed just below the overflow on the underside of the sink, which is really hard to see as it crammed up under the vanity.

The crafters offered to totally replace the top, or to patch the small spots underneath. Patch and it will be done Tuesday. New top and it will be Aug. 9.

Went for patch. No one ever will see it as I don't think most folks get on the floor of someone's bath, lie on their backs, get a flashlight and stare into the innards of the underside of the sink.
