[Shop-talk] copper tubing plumbing help solution

[john niolon]

After reading all the suggestions you guys offered and discussing the situation with my old plumber/pipefitter friend, this is what I came up with

Using two or three different sizes of sockets and finally a 1/2” socket extension with a ‘flare’ from the shaft to the head I slowly swaged the tube until
I  could insert a normal 3/4” section of tube inside it.  I sweat soldered those two pieces together.  

While we were digging the ditch for the sink drain we snagged the original line about 3 feet from where I ‘remembered’ it being.  I removed/replaced the damaged piece with standard
3/4 stick tubing and we found that the plumber had used stick tube from the house to the garage and then used the coil tubing to make the radius bend up thru the floor slab.  I’ll never know why... maybe an apprentice's
decision to finish up early one day
.
I did check the o.d. of the other end of the coiled tube and found it to be the same as the stick tubing (just like some of you said).   Soooooo the consensus that the tube had frozen and expanded enough to prevent fittings from going on the end was probably the right answer.  

after all the drain/ditch work and the repairs I installed a 3/4” ball valve and opened the valve on the other end... so far (4 hours)... no leaks, no fountains in the garage, no large wet spots in the yard
and I’m tired.  I should have done this 25 years ago when I built the house and was in my 40’s.

thanks for all the advise, opinion, and discussion... once again this fine group has saved my bacon..

later
