Reply to comment by nill0c in Need help removing a WC supply valve (is it soldered? or something else) by nill0c
Turn off the water to the house then open the valve then turn on a cold water faucet somewhere lower to get the water out of the line. If this is not possible keep the valve open and be prepared for the water in the copper line to have to boil off partially before the solder will melt. MAP gas helps as well since it burns hotter in the “water in the line” scenario

Oh yeah, should have updated I’ve had the water off and taken apart the valve, mapp gassed it (even though Mapp gas isn’t what it used to be) and laid heavy foil around the toilet and wall so I could really get it hot.
Pretty sure its not soldered in any way I’ve ever seen (I’ve replaced a water heater and pump tank that both needed cutting and sweating to install).
