I was installing a new kitchen sink and was using pvc plumbing
underneath. The threaded pipe coming out of the wall, however, was
(I believe) galvanized steel (1960's construction). Unfortunately,
the galvanized steel pipe was very corroded so as I was attaching the
pvc pipe to the galvanized steel pipe, the galvanized steel pipe
broke. So now there is not threaded end on the galvanized steel pipe.
Is there some type of coupling that I could purchase to connect the
pvc to the galvanized steel without a threaded end? Do I need to
replace the length of galvanized steel completely? I don't know much
about plumbing so I am looking for advice on what to do next. Do I
just need to call a plumber at this point?
The galvanized steel does not run through the entire house. It
appears to be on just undersink plumbing.
Thanks for any advice
very common problem. and home depot has just the
solution with flexible different sized rubber adaptors. i'm not
sure the real name but they have hose clamps at both ends
of a rubber tube. you buy the size that JUST fits over
your pipe and tighten it up good. these even take care
of those awful sections where you've installed a
mis-aligned pipe and need to bridge a few inches.
for longer requirements, i've always used auto radiator
hose. that stuff will last forever.
They are called FERNCO couplings. But if that pipe broke while
attaching PVC, it must be very weak. I'd replace it with PVC also.
It's probably just a foot or less to the elbow. Or, just run PVC to
the basement (assuming this is on the first floor).

I agree here that if the galvanized broke before you broke a pvc
coupling it's gone. To increase the likelihood you will decide to
take the advice to replace it rather than the quick term fix (at least
relatively soon, I wouldn't say not to put the sink together to use
and then plan out the job to repair the whole thing or get
professional help if you think it's over your head), I'll point out
that galvanized of that age and with such a weak spot in one place is
very likely on the verge of developing a leak somewhere else that may
not be so convenient in time and place as now while you have the water
shut off and are where you'll notice something amiss.
It probably won't fail tomorrow, but it is surprising how often after
disturbing any part of an old galvanized piping system there is
another failure very soon thereafter simply owing to the age and
apparently accelerated by breaking/disturbing the corrosion layer(s)...
FERNCO couplers are for DWV (drains), not water supply. This
is water supply methinks.
If you have galvanized water pipe _break_, the best course
of action is to take it out. Using a plumber if necessary.
