Using Old Material

I have some unused pipe and fittings that are 15-20 years old.... is there any harm introducing them into my plumbing system at this stage of the game?

Are they copper or iron? Are they used or new?
If new copper, go for it.
Used iron...NO.
Used copper...??? depends.

In this case, its copper pipe thats never been used. And its brass fittings that would be applied to copper pipe thats never been used.

In that case I see no reason why you can't use them. What type of copper is it (type k,L, or m)?

Type L

Coming in the same sizes as K, Type L copper tubing is used chiefly for medium-pressure interior plumbing, and for steam and hot-water heating systems. It should not be used outdoors in underground connections. The wall thickness of Type L is about half way between the wall thicknesses of Types K and M. In 3/4" size, its bursting pressure is about 4,000 pounds per square inch.

Type M

Available in sizes from 2 1/2" to 12", Type M is used where water conditions are normal for low-pressure plumbing. It is also used in low-pressure steam and hot-water heating systems. Its bursting pressure is 3,000 pounds per square inch in the 3/4" size.

As a general rule, use Type K whenever possible, Type L only when necessary, and Type M rarely. Type M might be used, for example, in a place where piping will not be subjected to considerable pressure and a lighter tubing is necessary.
