compression fittings are a time bomb waiting to happen.
Really great work
I am in Southern Califonia so do I need a valve with drain? Why do you need the drain?
he did not explain why he points the handle up
compression fittings leak a ton. I've never been a fan of them.
I have one of these valves that is leaking and corroded badly. It is between the hot and cold water coming into and out of my oil fired tankless furnace. DO I SHUT DOWN AND DRAIN EVERYTHING TO SOLDER A NEW VALVE IN ? I do not want to lose heat now in the middle of winter ! Thanks for your help .
I did this exactly but it leaks because the ferrule curled around the end of the pipe. Make sure the ferrule slides completely on to the pipe and doesn't overhang. I think the only way this method will work is if your pipe has a little play so you can close the gap a little. My pipes are fixed so this method doesn't work.
That's corrosion, copper and brass it causes galvanic action

Spray some white grease or T9 boeshield on that new valve and it will never corrode again.
what grit sandpaper did you use
how many teeth per inch should the minihacksaw have to cut through the copper pipe?
I'm an amateur and have done soldering. The press on looks easier but I don't trust it. Soldering is a pain but I prefer it.
STTTTEEEEEAAAAAMMMMMMM
Since they missed this…
Step one: Turn the water main off!
Bigger problem when this valve fails. You will have to cut the pipe to remove the ferules.
solder the SOB get er done, solder next time when replacing it,The End
Can this solder-less valve be used as a main valve for a house ?
That's great until it has to be replaced again. The compression fitting will have to be cut off and new pipe soldered the next time. Why not solder a new valve into place?
Common corrosion issue with copper…. Personally I would ripped out all that junky copper and replaced it with PEX. You will never ever have any type of corrosion issue with PEX while saving money at the same time. That valve will have to be replaced AGAIN in a few years.
