Cant get the valve off (with picture)
 
Come home today from lunch and a small pool in the bathroom. The braided tube from the valve to tank has a hole...

Can't replace the tube, because it is one piece with the valve. Go to Home Depot, get a new valve, and away I go.

Can't get that valve undone to save my life. It just spins the nut behind it and the pipe that goes into the wall (which I'm guessing is a bad thing). My question is, should I be trying to get that nut off the pipe, or the valve out of the nut? I tried both, the nut seems like its soldered on or something. The valve has threads that go into the nut which made me think it would come out, but to no avail. Two plumbing wrenches and I feel like I'm going to break the valve or snap the pipe in the wall.

Luckily the valve is good and is able to hold water back, so I'm kinda afraid to muscle it and get stuck if it breaks and I can't turn the main water on.

BTW, is that thing called a compression nut? Is it on there permanently? I'd really like to get that valve out of there and just screw a new one in...is there any tricks, like a good soaking of WD 40 or something? Sorry, I'm good with cars, not plumbing.

Thanks for the help. The house is about 30 years old, and I'm guessing this is the original valve. Thank goodness the house has copper pipes at least.

You should be able to hold the compression nut with one wrench and turn the valve body with another to get the valve off.

#1 call a licensed plumber and have it done right ......ie no floods
#2 do it your self and ill walk you thru it..... im new to this site and could probably use the charma...
#3 ok turn off your water supply to you residents,house at the jones valve at curb or at foundation ,usally a ball valve close to hose bib ...if apartment or condo look for the same except at curb.
#4 open bathroom sink faucet,and also low elevation valves like an outside hosebib ..once the water is out after 5 minutes or your ready to begin...
#5 you should go to a plumbing supply store before you start # 1 and buy a ferrell puller ,any less than 30$ is a piece off ****..i recommend do this with all your shut off valves,its a walk in the park ,believe me.... it will be at all water closets =toilets ,sinks, clothes washer....replace with the quarter turn valves much higher quality ..
#6 ok i think your saying your turning your shut off valve counter clockwise while holding the compression nut and

guess i talk to much lol...just want to be thorough...if what i mentioned is happening ...after making sure water is out of the system...with a large wrench behind the valve with about twenty pounds of pressure work the valve towards you from the ten oclock to two oclock position....sit on your ass if possible ...very important not to kink the half inch coming out of the wall bring it out and off the copper at the same elavation..good idea to wear good work gloves and support the wrench handle with left hand for your movement and your right hand at valve and behind wrench for your pressure towards you ...good luck
