New bathroom sink to low


I just installed a granite top in my bathroom and the new sink is about inch too deep. I also installed new faucets that come with its own color coated drain. After cutting the new drain pipe as short as I can, the P-trap is about an inch lower then the pipe coming out of the wall. I know three solutions are to either lower the pipe in the wall, or raise the granite top, or turn the P-trap around. I don't want to do either of 1st two and I've read you should never reverse the P-trap. I included two photos. The first picture is of gap between the P-trap and the pipe coming from the wall. I can actually get it closer then the photo shows, but you can get the point.

The 2nd photo shows about a 2 inch extension that I put between the pipe coming from the wall and the P-trap. Is this a valid configuration? Everything seems to work fine.

I was wondering the same thing.
Sometimes on here I've seen condinsate drains running to sinks for some odd reason.

Kind of looks like its leaking at the escutcheon, but maybe not. You may want to fill the sink, and pull the plug to put a real test on it.

If this is a bathroom sink...then what is the rubber hose on the side for?

Condensate- either roof top or attic unit- that's my guess.
I hope the OP shortened the 11/4" tailpiece so it doesn't block the wye branch

Thanks everyone for responding so quickly.

The hose coming in from the right side if the picture is my AC condensation drain from the attic. The sink to the left of this one, has one also. Seems like this is very common in Texas.

While I can cut that tailpiece a little more, it will make the gap closer but it will still put the P-Trap about 1/2 inch from the pipe coming from the wall. I know the picture makes it look like it will fit if I cut that tailpipe more, but it wouldn't. I did fill the sink all the way and then let it drain and there is still no leaks.

The escutcheon has some rust on it but that has been there a while. But thanks for pointing that out. I'll look into it.

I see that Ben's plumbing said it isn't a correct configuration but leave it if it works. That was my main question about if it is correct. I'm thinking it's not because the water has to travel higher from the bottom of the P-trap then it was intended to do. I think the P-Trap designed is such that it only has to ravel a short way up to exit the pipe coming out of the wall. Once you start extending that, then the water has to travel further up hill, which should not normally work very well, correct?

Maximum trap seal is 4". Thats not an arbitrary figure they came up with either. There is reasoning behind it- But you'll be OK with what you have- You'll have better chance of saving your wife ring when it goes down the drain
