Connecting galvanized pipe to PVC
With no threads.

I’m stumped here. I had to remove the old water pump at the camp, and all the metal 1” suction piping was so corroded, I ended up having to cut it out (cut in the middle of a 1” nipple). Now I need a method of attaching more 1” piping to that cut nipple. What do you plumbing experts think?

Multiple Options:

1. Flexible PVC Coupling Home Depot
2. 1" dye to thread it. Get a 1" NPT x Socket PVC adapter.

Galvanzied Union . its a compression fitting on one end for the galvanized pipe and threaded on the other end so you can screw a PVC fitting to it. I've used these in old houses to repair corroded pipe and they work great.

No hub clamp would be cheapest and easiest.

re: Connecting galvanized pipe to PVC
if you cut the 1" nipple then unscrew whats left of it and then add a pvc fitting to the threads

otherwise go farther back the pipe to the next fitting and unscrew it and make your plastic connection there

word to the wise, male pvc fitting screwed into a thread coupling always will start to leak. only use a female pvc coupling to screw over the pipe threads and that wont ever leak unless you over tighten it to the point it cracks on you

another tip is is you have a bad section somewhere then the rest of the line is just as bad so its best if you just run a complete full new pvc line the whole way to where it goes into the house so you are back fixing leaks again next month

re: Connecting galvanized pipe to PVC
compression coupling from HD or plumbing outlet...
I used one when the pipe feeding the house started leaking...
two couplings with a 10' section of PVC in the middle...
been working fine for years now...

Problem is, I can’t unscrew any of the fittings. Tried with 18” pipe wrenches and got nowhere.

trouble is thats my whole point, usually once one connection rusts through its time to replace everything under ground

above ground stuff will unscrew, it just might take some effort and if need be add a cheater pipe

Cut them out and use a no hub clamp to connect the old galvanized to the new pvc.

Cut and file the galvanized. File the rough edges attache the no hub clamp and tighten it. Attach the pvc to the other end of the no hub clamp.
