i should try to clairify this for everyone.
ok now when you say silver solder that term is when you brase with a special mostly silver brasing rod.that is the strongest off all brasing or solding.it is second only to welding.but no one here is every going to use that stuff.i have some at work but for one is exspensive and very hard to use.
i think you are refering to a plumers solder lthat has a silver additive like what i am using.mine is a 95/5 lead free solder with silver added for extra strengh.
i am going to give everyone a site to go to.it will show how to properly solder and like it says if done properly the soldered joint will be as strong as the copper pipe you are soldering to.

and also a picture i have showing the spec of a 95/5 solder and that it will withstand 540 psi at 200f degrees so you wont have a problem if done correct.
my entire system is soldered with 95/5 silver based lead free solder napa part #777-1865
