Galvanized to PVC
 

Opened the water supply valve for my backyard water spigot only to
discover a leak. Pipe is galvanized extending about 24" above ground
level with a 180 degree elbow to which a standard valve is attached.
Water leak found in the threads where the elbow connects to the stand up
pipe.

Being at least 50 years old the connection is rather corroded. Two pipe
wrenches wouldn't budge it. Have to be careful as I don't wish to crack
the pipe below ground level.

Two questions:

1) Any easy way to free up that elbow?

2) Assuming answer to #1 is no, would it be possible to use a sawzall to
cut of the elbow and somehow transition over to pvc?

If pipe gets too corroded, the pipe just squashes when you try to hold it with a
pipe wrench with enough force to loosen a rusted joint.

There are PVC compression couplings. The cheapest way might be a 2" length of
rubber hose with an I.D. equal to the O.D. of the pipe, and 2 hose clamps.

Put a six foot breaker bar on each wrench.

Sure. Just thread the fresh pipe end after you cut it. Threaded PVC
fittings are common.

Please be kind enough to take some pictures of that 180
degree elbow, and post them to a photos hosting site. I'm
not sure I've ever seen one of those.

As to freeing up a rotted on elbow, Mapp or acetylene torch,
to heat the elbow. And then try the two wrenches while it's
still plenty hot. I doubt a fermo connector would work on a
water intake. Some threading kits are available to cut new
threads into the cut end of a pipe. But, that's risky.

If heat doesn't work, with the two wrenches. Then try heat
and then spray the threads with WD-4o till it cools down.
sometimes helps. I've also heard of heating it, and then
dripping candle wax onto the threads. but with a pipe coming
through the floor, that's hard to drip uphill.

That's a metaphor, yes?

Sounds like a memory thing, to me. Like the stala*C*tites
have a C. C for ceiling. stal*G*mites, G for Ground.

Just a mnemonic to remember the principle, like the
stelactite/stelagmite thing.
"the mites go up and the tites come down"

I believe that would be a "pipe cap" ;)

2: Probably best not to try to free it up. Cut the pipe below the
elbow, install a "Dressler Coupling" (compression fitting), with a
stub of new iron pipe and elbow. I would bother with the PVC.

As someone else said: If you do go to PVC be sure the PVC to iron
adapter is a male. Just screwing a female pvc onto iron can split the
coupling (I did it and discovered the error after having to dig it up
to fix).

Can u post pic of "180 degree" elbow ??? ;-)

Stalactites are stuck tight to the ceiling. Stalagmites might reach the ceiling.

Don't be afraid to really romp on it. Collapse the pipe and twist it
off if you have to. It will be easier to use a cold chisel and hammer
to collapse the pipe threads and peel them away from the inside of the
fitting.

A transition will never seal on the rough galvanized. Compression
fittings are for smooth pipes. A rubber transition will not withstand
the pressure.

And after you get done butchering a $1.25 fitting you throw it in the
trash and buy a new one anyhow.

Perhaps you should be re-educating 60 years of plumbers who have been
using them then.

BS and see above.
