Quick question: how reliable and non-leaky are compression fittings for shut-off valves? I've heard different things from different people. This would be for installing three shutoff valves for a toilet and the hot and cold sink water supply.
The supply copper pipe is coming out of the wall, current 30YO supply valves are soldered on to it. Once I cut the old valves off, I'd be kinda close to the drywall. Is there a significantly higher chance of a leak using compression fittings here rather than soldered on fittings? Talking about the type where you put the nut on the copper pipe first, then put the compressible copper sleeve on the pipe, and screw the nut into the rest of the fitting, trapping and compressing the copper sleeve.
