What is the additive inverse of the fraction, 6/7?
Copper is the way to go. It's the easiest to put it. It doesn't build up with calcification and won't corrode. It's extremely easy to work with using no threads.
-6/7 because 6/7 added to -6/7 equals zero. The additive inverse of a number is the number which added to the given number gives zero.
-6/7. You can find the additive inverse, or opposite, by multiplying by -1 (changing its sign). Hope this helps.
I use Pex exclusivly there is nothing faster! It withstands many freeze thaw cycles. It can be run with far less fittings. does not corrode or plug up with iron.
copper is the way to go if doing it yourself. easy to cut and route without the hassel of threading. sweating is relatively easy if you clean and prep the joints properly. buy the coerrect tools and please use lead free solder with flux designed for such.
