I'm replacing the shower only 2-handle faucet fixture and since the
plumbing is 43 years old I'd like to replace the very green hot and
cold water 1/2" copper supply lines to it at the same time. Is the
rolled Soft Type L copper pipe which Home Depot sells OK for hot
water? The pipe I need to replace is in the shower wall, not in
concrete. Total length is about 5 feet for each line.
this is Turtle.
Type L Soft will last a good amount of time like 30+ years. Now Type K soft
will out last you for sure 50+ years. Type L is made for air conditioning
freon lines and K is made for plumbing and long lasting air conditioning
freon lines from leaks , for K is thicker. .
Now type L will do anything type K will do and holding up to a beating or
The reason I want to use a soft copper pipe, like Type L, is that
there is a big 2" steel vent pipe in the way. I need to either bend
the new pipe behind the vent, or use a bunch of elbows if I have to
use a rigid copper pipe.
Go ahead and use it. My mom's house is plumbed in all soft copper. It was
plumbed that way 20+ years ago and has held up well. The reason it was
plumbed with soft copper is that it is built on a "crawl" space which is so
low nobody could crawl through it. So all the supply lines were pulled
through with an electricians fish tape.
you mean K is a bit *thicker*, right? M is the thinnest, often used in 3/4"
to ~1 1/4" sizes for hot water heating systems where the pressure's low
below 20 psi or so, but yea, if you can't get hard drawn L there than K coil
will do it. Slide unslit insulation over it too when you install it.
This is Turtle.
I can only speak of Copper tubing used by HVAC / R peoples. We use L copper
for freon lines with pressure up to 500+ psi. it is rated above this but
this is the working pressures we use or think of it as. If i'm installing
HVAC equipment bigger than 5 tons or Refrigeration systems , i will use Type
K Soft or hard for to get a thicker and more duriable tubing to hold up to
the bad treatment of these systems. Now to Type M awwwww Never used it.
Now there is suppose to be a difference between refrigeration copper and
plumbing copper. don't know for i've only used refrigeration copper from my
warehouse and never investigate the difference.
