If you get drips of water coming through your pipes even with the main shutoff valve completely closed, it's probably time to replace the shutoff with a new ball valve.

Test the “street-side” valve where the water enters the house. Since that valve is just as old, test it to make sure it closes all the way and reopens again. If that valve needs replacement, contact

your water utility to shut off the main valve at the curb. Then check out the electrical system “bonding jumper” that runs from a clamp on the house side of the meter to a clamp on the street side. unscrew the old valve with the bonding jumper wire in place, fine. can't, do not disconnect it. way to work around this problem is to install a longer section of copper wire and two new clamps (6AWG for 100-amp service, 4AWG for 200-ampThen remove the short you're ready to shut down the water and replace the valve as shown. As title says I am trying to figure out how to remove the old shut off valve from the pipe. I've been watching lot of videos, reading up on articles and all seem to deal with compression fit type but what I have at work (1st photo) and home (2nd photo) seem different from what I am dealing with. (Top photo is just a reference) It doesn't look like it is soldered on either (at least that's what I think)

plumbing toilet pipe removal valve Typically, the valve solders to the 1/2 inch water source pipe. the outlet is a pretty standard 3/8" compression fitting. It is a little hard to tell from your pics, but it is rare that the valve would be a threaded fitting to the water source, but not unheard of. The differences between the valves pictured are that the top pic is a 90 degree 1/4 turn valve and the bottom pic is a straight multi-turn valve. If you are going to replace them, do yourself a favor and use nothing less than a 1/4 turn stainless steel ball valve. They are available in both straight and 90 degree styles. Assuming they are solder on, you must heat them to melt the solder and remove them, or cut them free with a tubing cutter as close to the existing valve as possible. If you unsolder them, take great care to remove all the old solder and clean/smooth the pipe end well before attempting to solder a new valve on. A basic knowledge of sweating pipes is needed for this project as well as basic plumbing tools like a tubing cutter, torch, abrasive cloth, flux and solder.

It looks like it is soldered. You can either resolder on another valve or use a compression valve. I use compression valves for shut-offs and just installed this one. If it isn't soldered then then the nut closest to the wall turns out and there is a pin under it. You have to take the pin out to release the compression valve - if it were a sharkbite or similar you would need to buy a little horseshoe device to release it. With the water off. Example of compression valve - every store has there own brands for these. Also in most stores they are not with plumbing they are with toilet parts. Make sure you get the right size. Looks like yours is 1/2 to 3/8. This is a 10 minute job! - shut off water - cut copper as close to current shut-off as possible. - clean inside and outside of copper - slide compression fitting on - turn on water - turn valve on and off to make sure there are no leaks It looks like both ends just screw on. Turn off the house water, unscrew both ends, take it with you to get the replacement (or make several trips like me).
