We think the drain pipe in the wall is too high for our small pedestal sink.

The pop-up drain will not open completely because the bottom of the "tail piece" or whatever it is called hits the top of the drain pipe.

Our pedestal sink base is not completely open in the back -- there is a 2" piece across right where the p-trap connected to the drain pipe should enter the base.

The drain pipe is 20" off the floor. It would be just fine if is was at 18".

Is there anything we can do other than move the drain pipe down 2" in the wall?

Thanks.

Do you mean that the rod that you push down or pull up to open or close the drain hits the piping?

natalieblueeyes

Yes, the rod that you push up and down to open the pop-up drain.

That rod hits the drain pipe (waste pipe) coming out of the wall. The drain pipe prevents the rod from going all the way down.

The rod should have a metal strap attached to it via a bolt. That strap should be attached to a horzontal rod that works the pop up. Adjust by loosing bolt and sliding up the rod or cut off part of the strap and use another hole. If necessary you can cut off an inch or so of the rod. You may be able to twist the part that the horzontal rod goes into around to one side so that the rod does not hit the pipe. If you assembly is not set up this way, post a picture.

Here is a picture that should help with Harold's description.

Let him know by name what you think he said...then let him tell you if he agrees...

You guys are my idols with all your pics. Harold is correct about the clevis length, you can cut it or bend it. The 18" stub out would have been my standard rough in and that would have avoided the issue but thats water over the dam.

I had tried moving the horizontal pivot bar up a notch on the clevis, but when I did that the drain in the sink doesn't open as much.

There is some play in moving the clevis to the side but not enough to avoid the drain pipe.

I had called the manufacturer (Delta) about cutting off part of the clevis and the guy I talked to thought it would void the warranty on the faucet. That doesn't make alot of sense.

But even if I solve this problem, I still have the problem of the p-trap when it is connected to the drain pipe not fitting in the back of the pedestal sink base.

I agree that that doesn't make a lot of sense. He probably didn't know what part you were speaking off. I'd cut it. You can always give up a cup of coffee and by another one at Home Depot. If you don't want to cut it, Just bend it below the point where the horizontal rod is attached.

On the other problem;
If part of the fixture is covering the drain pipe coming out of the wall I'm afraid that you don't have any choice but to lower the drain pipe.

Here is a picture of the p-trap, drain pipe and pedestal sink base. It may be hard to see in the picture, but the p-trap hits right at the cross piece on the base. (We haven't cut the drain pipe yet.)

If the drain pipe was even 1" lower, it would be o.k.

Any ideas of what to do -- without having to lower the drain pipe.

Thanks.
