I have a vintage sink and want to connect it to a standard water supply line. The connectors for the sink at roughly 1 1/4" threaded and the suply line connection is roughly 3/8". What do I need to connect the two?

It seems that size of drain and water supplies are standard. Use 1 1/4" to 1 1/2" adaptor for drain and 3/8" Comp x ( what ever size of angle stop you have ) for water supplies. All can be purchased in Home Depot.

Vintage sink! I assume by the measures that you have a wall hung lavatory,(see image) and not a kitchen sink. Correct? If so do you have the mounting bracket for it? Can you ngive me more details such as, is there water and drainage where you wish to install? This IS a wall hung and not a vanity drop in isn't it? Back to you, Tom

I forgot to say this is a pedestal sink.

Here is a photo of the faucet connector: durkes.com/image_host/connector2.jpg

The pedestal: durkes.com/image_host/pedestal.jpg

The bowl: durkes.com/image_host/bowl.jpg

Now I have a different issue - how to anchor it to the wall. The anchors are through the bottom of the bowl part and not out of the back, which would be much easier to work with, of course.durkes.com/image_host/anchor.jpg

I'm a decent carpenter and have done a lot of home repair (plastering, drywall, built-in bookcases, kitchen, etc.) but plumbing is a different art form. The more I read about setting up a pedestal, the more difficult it seems. I think it's a porcelain piece (pre-war Crane Norwich) so I would prefer not to ruin it.

Really appreciate the help here. I may surrender and get a pro in but given that I'm out of work, would rather not.

The photo links didn't work in my reply and the system won't let me edit the posts so here are the correct links:

Pedestal sinks are tricky to install.

You should proceed as follows:

1. Mount faucet and drain on the sink first, install pop up assembly, connect water supplies on the faucet
2. Dry-Test: Set up ped-lav in its place as if it was installed
3. Level. Mark holes on the wall, mark leg outline on the floor. Important: NOW is the time to measure and cut your drain drain
4. Dry fit the drain and trap
5. Remove bowl and leg away from the wall
6. Pre-drill holes
7. Put caulking on the bottom of the leg and on the top
8. Apply caulk on the back side of the sink
9. Put let in its place
10. Sit sink on the bolts and on top of the leg
11. Align all
12. Insert nuts and large washers and tighten bowl against the wall
13. Connect drain, trap
14. Connect water
15. Recaulk base of the leg and also the seam between the sink bowl and the leg
16. Caulk where sink meets the wall
17. Turn water On, test

Dsdurkes...

That faucet is missing its union nut and adapter...

Here, you would normally find a union nut holding a 1/2" IPS female adapter to the faucet. In days back when, we would pipe these up using solid brass threaded piping materials, but in this case the union nut with the adapter is missing and will be difficult to find a substitution...although a substitution may actually be available.

I would take the below picture (from your link) to a local plumbing supply wholesaler and see if the guys at the counter may have an old faucet box of parts that have the needed parts.

To give an idea of what I am talking about here, the union nut and female adapters that you need look like the union adapter on top of the faucet below (see bottom image). This is not a 1/2" union fitting, but a very specific faucet union... OK?

If you are lucky enough to get the right union fitting then you can adapt using a 1/2" IPS brass nipple and then purchase normal 1/2" IPS x 3/8" OD compression lavatory supply hoses to connect all up.

Now, why are you trying to reuse such an old faucet? It's probably not worth all the trouble/expense trying to repair the old faucet because all parts including the seats will need to be replaced. You can find some great faucets online at Faucets, Toilets, Plumbing Supplies from Kohler, Moen at PlumberSurplus.com and other places for pretty reasonable price nowadays. Something to consider at least... maybe?

Anchoring this pedastal is tricky, but we can figure something out, I'm sure. Let us know what you are thinking here, first, OK?

Back to you...
