Installed shut off valves on tub

Took on this task last weekend. I felt kind of clever when I figured out I could cut the copper with my mini-tube cutter by turning it over. I placed it on way and went back and forth to the limits. Then turned it over on the pipe making sure it was in the same cut line. Then back and forth the limited rotation that way and bingo all done. I felt this was way better than using a hacksaw or cutoff wheel and getting a bunch of debris in the pipe. Anyone else used this technique? Sorry, not enough confidence to sweat in valves, so I used these compression style.

Well because I could. No just tired of needing to shut the water off in the whole house when needing to fix the tub faucet drip. I did replace the whole stem assembly this time because the edge of the recess that holds the rubber washer were breaking away. Also the access panel which is in a closet had already been cut. Maybe you don?t live with other folks in your dwelling like SWMBO. Doesn?t like the inconvenience of the whole house not having water.
 
Looks good!

I too was lacking confidence in my soldering ability. Finally out of necessity I decided to learn how.

It?s an incredible time and work saver!

Map gas, soldering paste, plumbing solder, Emory cloth, and a bucket of water (fire extinguisher), it?s actually hard to mess it up!

A few practice pieces, some YouTube time, and good to go!
 

I (The plumber) re-plumbed the whole house this summer he put them under the house I never thought to put them behind the wall while I had it cut open...

He could solder I got my lesson $$$$$
 


Shut off valves are mandatory down here , every sink ,trough shower, bath and basin must have them fitted on both hot and cold lines . I used to think it was a waste of time and resources until I had a defective flick mixer , it took two weeks for a replacement cartridge to arrive . During that time I only had to shut the cold supply off to one hand basin rather than the whole house .
 


Over the years I have added a number of shut-offs in the house. I learned to sweat joints on the job many years ago but compression and shark bite fittings certainly have their places. We used to carry a set of 1/2 and 3/4 compression adapters on each truck in case of a problem situation in order to get the tech out of a jam and home early. That was my company's mission statement. "get the techs home early"
 
I used to be really bad at soldering into old pipes. New ones I could do but what I discovered was that I was using an old propane torch that didn't have enough heat so the joints came up slowly and it the flux flowed out of the joint and the pipe oxidized.

My solution came in the form of a Map gas torch that can heat faster and get solder into the joint quicker.

I also us the old bread trick on pipes that have a small amount of water in them. Take a piece of white bread and make a small ball and jam it into the pipe. It will soak up any water before it gets to the joint and prevent it from generating steam. Afterwards the water flow in the pipe will break up the wad of bread and flush it out of the line. If you are using a faucet with a strainer on it remove that first before flushing or it could clog.
 
You're right, you need good heat, but also the cleaner the better too. Maybe more important.

have found that there is a "window"....too little or too much heat yield bad ending

2X on window of correct heat.
 
Threw the mini cutter away after I started using a Nerrad ratchetting tube cutter and a swet flow stopper.
 
Don't know if mandatory here in US fot to have shutoffs every place anf where you can get to then easily but it is only common sence to have them. And have on main lines as well.
 
I've had a plumber tell me that they can get wax plugs to stop water. After they soldered the fitting, then melt the wax plug.
 
The city I live close to code requires cutoff on customer side of meter, one next building and one on every water tap. I live in country so mine is turn of water pump and bleed down.
 
And when that kitchin sink valve blows as I have had how well do you want to clean up the 50+ gallons of water that will be on the kitchen floor before you can turn the pump off and then blede the tank in a different spot that the water will not hurt.
