Soldering question - temp barrier

When soldering I always fear I am heating up adjacent joints, I worry that they may come loose and leak.

Should I be wrapping adjacent joints with a wet rag? And if so, how close between joints would it be a good idea to create a temperature barrier?

If the joints are within 5 to 6 inches then yes, I usually wrap with a wet rag. Never had a failure as yet.

I guess the pros will say Im doing something wrong if I have joints within 3-4 inches of each other, but that is the case.

I used a wet rag also at those joints and never had a problem

Never heard that having joints close together is not right. I've seen joints soldered right next to each other.

There can be problems with joints close together...if you aren't using the right torch. A typical homeowner will use a propane torch which doesn't heat the joints as quickly and can allow heat to get to nearby connections.

Better to use MAPP or acetylene.

Yes I got the advice to use MAPP on this forum. Best advice I ever got. I could not believe what a difference it makes and I was in fact able to heat the joints quickly.
