installation without soldering and without iron gas pipe

I gather that soldering can be avoided by using flexible gas lines with compression ring pipe connections. And now, even the gas line connecting directly to the water heater can be a flexible hose line instead of a rigid iron pipe. Kits such as make this possible. Apparently, such products make installation easier for DIY installation easier than ever before. Is this perspective correct?

And, if a ball valve on a cold-water inlet line needs replacing, that could also be done without soldering by using a valve that can be installed using a compression ring. Right?

When working with gas lines...... there is no soldering. Traditional gas installations are done with iron pipe. All pipes and fittings are threaded together. Most pros and serious DIY'ers will connect the iron pipe directly to the water heater. If your pipe is well supported.... it is acceptable to use a short flex line to connect the iron pipe to the water heater.

On copper water lines you can use valves with compression fittings or another popular choice is called sharkbite fittings. These fittings and valves can be pressed directly onto clean copper pipe with no burrs.

By the way, just for clarification, those flex gas lines typically to connect from gas supply to appliance use flared fitting. So many people come into the store thinking they can connect their appliance directly to the pipe or appliance without the flare adapter that comes with the flex pipe kit. People tend to leave the flare adapter attached to the old appliance. Besides it's always advised to buy a new flex hose kit when installing a new appliance.
