Sorry about the dark pic. Here's the new pic of my shut-off valve.

You have a 1/2" female thread by 1/4" compression angle stop. Do you wish to repair or replace? Tom

Replace it since the washer seems to have disintergrated. Even when I shut it off, the hot water still flows from the faucet. The other shut-off valve for cold water works fine.

Thanks,
KK

First turn the water off at the house shut off. Open a faucet to relieve pressure. Unscrew the 1/4" compression nut. Now take two wrenches. put one on the galvanized nipple on the right hand side and the other on the back part of the angle stop on the left. Now while holding back on the nipple with your wrench turn the angle stop out counterclockwise with the other. Do not let the nipple turn. Unscrew and remove the old angle stop.
You should now be ready to install the new angle stop. Wrap the nipples threads with a few turns of Teflon Tape. Now comes the tricky part Tighten the angle stop till you're almost through but just before you reach the vertical guide the 1/4" chrome supply into the male 1/4" thread. Now finish turning the stop up until the 1/4"threads catch and you can tighten the1/4" compression nut. Turn the water on and test for leaks. Good luck. Tom

Hi Tom:

Thanks so much for your detailed reply. Somehow, replacing this shut-off valve is looking a lot more complicated than replacing the compression faucet. Since I have sub-par plumbing skills (and limited tools), I think I will leave the shut-off valve the way it is.

So if I don't replace the shut-off valve and only try to replace the stainless steel pipes with braided pipes, is this as simple as removing the nuts at both the ends of the existing stainless steel pipes (one at the shut-off valve and the other at the compression faucet), and using the braided pipe instead of the existing stainless steel pipe? If so, what would be the specs on the braided pipe that I need? Also, is a wrench enough for the job?

Regards,
KK

Hi Tom:

Just checking if you had a reply for my previous post. Your reply will be appreciated as always.

Regards,
KK

However, even if I turn off the shut off valve for the hot water under the sink, I still get water when the handle for the hot water of the compression faucet is turned! Why is this? BTW, this shut off valve is leaking as well so I will be repairing this. But is it possible that you turn off the shut off valve yet is sends water up to the sink? I am sure I am turning it off completely.

Please reply.

Thanks,

Yes it is possible and very likely that your valves under the sink are bad. Generally they only have thin rubber washers inside that act as the seal to shut off the water. To fix:
Shut off valves down below in basement ceiling, check faucet to see if water is in fact off, the replace the valves under sink. If there are no valves down below, you can shut main valve off for whole house. That will shut off hot and cold

Assuming your faucet, not the angle stop, is standard, you should be able to replace the ridgid chrome supply tube with a 1/2"x3/8"x20" braided supply with nothing more than a crescent wrench.

Hey Fellas,

Is it possible to have a copper nipple instead of a metal nipple? I'm looking at my angle stop and it doesn't have a compression nut.

Thanks a bunch.

Hi EATANDTRAVEL...

Yes, it's possible to have a copper extension tube on a shutoff... like in my picture below:

This is a SWEAT stop that gets soldered on to install and to remove.

Is this what you are talking about? If so, do you need to know how to take it off and install a new one? IS yours leaking?

The compression nut is the small nut on top that feeds the toilet or lavatory faucet.

Let us know more...

Thanks... MARK

you have 1/2" IP by 3/8 comp. angle stop. Remove it. Buy 1/2"IP x 1/2" IP angle stop. Use 1/2" water supply. You can get it in Home Depot.

massplumber2008,

I was under the impression that you had to have a metal nipple. My set up is jut like the kutra's pictures but mine has a copper nipple. I thought that was weird.

Thanks for your help.

No, the sink connector can be flex. It is lot easier to install and is hand-tight.

OH... no not weird at all E&T...

That would be a brass nipple and is the same as the nipple above but the nipple above is chrome plated is all...

All threaded water pipes are galvanized or brass. Again, most of the brass ones used in finish work are chrome plated.

Let me know if you have any more questions...

MILO....Eatandtravel hijacked an old thread....so need to read his post to understand what we are talking about...;) Have a good day!

MARK

massplumber2008,

Thanks a bunch again.
