Hi all: I recently noticed that Home Depot is selling a copper bonding
expoxy product in the plumbing dept. that's billed as being as good as
solder. Seems like it might be a useful alternative to use on joints in
tight, enclosed areas where heating the parts with an open flame is
difficult/dangerous. Would appreciate any informed opinions regarding
whether or not the product referenced above might be an acceptable
substitute for solder in the circumstances mentioned. Thanks for your
I hate the words "should" and "maybe."
When one considers that usually once you solder a joint, you cover it up
with other stuff, and if there's a problem, there's a major problem ripping
it out and doing it again, plus the water damage, why would anyone even
consider doing it any other way but solder?
Yes, soldering is dangerous. But they make all sorts of shields and
blankets, and lots of times, the joints are out where there is very little
danger. Some pieces can be made in trees, and never come in contact with
anything dangerous or flammable.
Soldering isn't rocket surgery. I believe I could teach a monkey to do it
in a day, and a twentysomething lip pierced moron in two days. Get a clean
joint, use flux, don't overheat, learn how to flow solder, and bingo.
I have repaired some amazing things with JB Weld and other epoxies. But,
when you consider thermal expansion, water hammer, rollercoaster
temperatures, and other things, I'll stick with solder, even if epoxy is
proven to be adequate for copper pipe. You can still get your mix wrong
with epoxies, have surface contaminants, incorrect cleaning, and other
things that will cause ultimate failure.
And when there is a failure, you will be ripping and tearing, repairing
sodden materials, and most probably be dealing with mold down the line.
IIRC, years ago, they came up with this new water piping system that used
crimps and swages that was going to revolutionize the water pipe systems in
housing. All it turned into was ruined houses and class action suits.
If you can't at least solder, or learn how to do so in a day, you shouldn't
be messing with copper. It's that important.
Just my two pennies.
Geez, am I getting old or what?
I see people today who are twenty years old and:
they can't make change for a $20 without a cash register......
they don't know the difference between your and you're .......
like, kewl, and dude are their vocabulary .............
they want $20 an hour for menial work .............
they have a devil tattooed on their forehead and a laundry sized safety pin
though their nose and wonder why they can't get hired even as a waiter
need I go on?
There are times when soldering a joint can be very tough like in a
hole in the ground which is the lowest point in your plumbing. I like
the bread idea and have never heard it before. I pony up the cash for
a compression fitting when soldering is to difficult.
Someone just told me it works great if you can't get all the water out of
the line to solider. I know they make some epoxies that dry underwater. The
only thing is this is all new stuff so it hasn't had the test of time.
Believe it or not sometimes bread residue will clog a fixture. Sometimes I
use a shop vac to suck water out or a compressor blow back threw the system
and then they do make gelatin plugs to jamb up the pipe. Yes I have used
bread more than once.
I soldered water pipes for the first time last weekend. I thought it
was easy enough to do, but I have had lots of experience with
electrical soldering so that helped. I didn't even bother practicing
first. The hardest part was that afer I adjusted the flame I had to
deal with gusts of wind coming in through a crawl space and changing
the size of my flame on me. I can say that if you have a lot of
patience and prep everything properly, use enough flux, and heat up
the pipes enough, then it should work. I had some vertical pipes with
water in them that I drained by sticking a straw in them and sucking
out the water as far as I could and that was enough to make it easy to

They might even have tested it for a few years in some small to
middle-sized application, in Denver or Mongolia, but I would like 100
year test. How long has soldered copper been used? There are
probably plenty of pipes around from the first decade of its use. I
don't think the rest of my house will last as long, but I think the
solder joints will last 200 years.
Another product made for incoherent people who are too stupid or lazy
to solder the pipes together. Besides possibly being a product that
will fail after a few years, I wonder how many hours or days one has
to wait for the stuff to dry? Solder hardens in seconds, and has been
used forever. I'll stick to solder. (There are no places where pipes
can not be soldered, they make asbestos pads to prevent burning wood,
and a little water sprayed on charred wood always helps). OK, now go
ahead and post lots of flames about using asbestos pads, and how
dangerous asbestos is........
Actually, Gerry, I'm both stupid AND lazy but, even so, I've managed to
become reasonably adept with flux, solder and torch. However I don't enjoy
doing it in confined spaces and was just wondering if there might be an
alternative that's worthy of consideration, although the consensus seems to
be to the contrary. Thanks for your insightful observations; they were
greatly appreciated, as was the glowing compliment!
I used it once several years ago. The joints are still leak free. That
doesn't prove anything, but is encouraging.
However, I went to use it last year and it had gone bad. Way too expensive
for two joints!
I'd think so, without any personal experience. But you'll never get
it apart again if it leaks.
You can always put some sheet metal and a wet rag, if it will fit,
between the joint and any flammable material. You can get a baking
pan at Goodwill for a quarter and cut it to fit. There's really
nothing wrong with scorching the snot out of surrounding wood,
sometimes it can't be avoided.
Bust into your shower connection and you'll likely find burnt wood.
It ain't no biggie. Just be careful.
I'd guess less, I had to take apart some epoxied aluminum fittings on a
boat and heat softened the epoxy easily. Usually about 300 deg F does
