I have an old wall mounted sink I'd like to replace. I've done it with a newer style but this particular, very neglected washroom we never use, has valves that appear to be, I'd guess compression fittings?

There are bolts that attach to the faucet right near the top of the sink, up underneath the back. Loosening these is proving extremely difficult as there is almost no room to do so, even laying down looking up into it.

In the picture the left valve is coldwater, one split going to the sink, the other the toilet. The right is cold. Both valves function, amazingly and very grudgingly, and I can turn off the water to those valves completely from elsewhere in the house as well.

I'd like to remove and replace those valves and replace them if possible as it doesn't seem re attaching to them is an option. How do I go about this? Also, will it be possible to have a valve that allows for two out puts so the toilet and sink can work off the same one still? It's a very small washroom and that's the most convenient.

Thank you for any help, I've been scouring the internet and haven't found something similar, they all seem to have threads already. If the task is too daunting I'll call in a plumber of course. Just want to see what it involves first. Thanks again.

Hi Eswift

I tried to upload the site... here's what I got:

"Imgur is over capacity!

Sorry! We're busy running around with our hair on fire because Imgur is over capacity! This can happen when the site is under very heavy load, or while we're doing maintenance. Please try again in a few minutes."

I'll try again in the AM.

Between the 4-6 of us that post daily on this page we should be able to help once we see the picture or get a brand name, etc. Give it some time, otherwise, try uploading direct to the site by clicking on "go advanced". I think that's it... *UGH*!

Back to you...

Sorry about that, imgur is usually very reliable. I will try to upload them here.

Those shut offs are soldered on and if they work you can use them again.

To remove the sink you need to cut the water pipes about 10" down from the sink. Disconnect the drain pipe, too and then the entire sink should just lift up and off the hanger that is screwed into the wall. If there are bolts in the sides of the sink, use 3/8" ratchet and socket to remove these.

Once you get the old sink off the wall you can purchase some compression fittings, or even new shutoffs and connect the water lines to the new faucet with braided SS flexible water supply tubes. The drain should be pretty straight forward.

More questions? Let me know!

Thank you very much! Would new valves also be soldered onto the existing pipe, like the old ones are, after it was cut? I'd like to replace those old valves, as they are difficult to move and really old. However, I don't have the tools to solder them on, so I'd have to decide whether to just avoid doing that, with compression fittings as you said (I can rent these tools and have used them before), or hiring someone to do it.

Hi again...

If the old shutoffs work then I think you'd be OK to just reuse them and install new 5/8" OD compression x 3/8" OD compression straight adapters and hook the braided SS hoses and be done with it.

If you pull a plumber in to install new shutoffs then I would just have him do the whole job... shouldn't take much longer to install a faucet and sink, right?

Back to you...
