I have had to fix these a few times, but I cut and thread the pipe, then use a galvanized tee and union. On my own galvanized sprinkler system I have turned the tee horizontal and used a 90 degree street elbow to prevent breaking off sprinklers. The additions to my sprinkler system I have made with PVC but do not like funny pipe. My galvanized fittings are all salvaged from scrap, and I regalvanize and rethread them so they are always handy.
@licalicawah First, try examining the pipes closely after you get the water out of the hole. Dry the pipes off with a rag. Often times the broken pipe will continue to leak water out of the break(bad spot). If this doesn't work you will have to pressure up the line and feel around the pipe with the water pressure against it. This will tell you which pipe is leaking even if the hole is full of water. The leaking pipe will push pressure against your hand.
I just had to do this, but I use a galvanized female threaded coupling, then I cut of a schedule 80 PCV Nipple threaded it into that with tape, then I use a schedule 80 coupling and attached that to Schedule 40 PVC line.
@biironbar I tried using a nipple extractor in a number of tees on this project but the broken off risers were rusted into the tee and I ended up splitting tees trying to remove the nipples. You're seeing the steps after trying a nipple extractor.
We had to put full length 4 inch ductile underground, and full length 4 inch galvanize pipes on the roof for fire sprinkler. Must be nice to install 3/4 “ pipes :3
Have you done the gas pressure calculations to determine whether you will have sufficient pressure at the dryer? Regardless, given the potential "boom" factor for getting it wrong, I'd hire a plumber for this one.
@chargermopar Is it possible to do this same repair using galvanized pipe instead of pvc? I want to add a T fitting along my gas line in my attic to run another line for a dryer but I can't figure out how to screw the T fitting in without unscrewing the nipple that connect the T to the main line. Any suggestions?
Could the same method be used to tee into my galvanized service line to feed a sprinkler system? I'm trying to research ways to tee into it without replacing the galvanized from the meter into the house.
***** I've had good luck using an IPS brass dresser tee. The galvanized pipe needs to be in pretty good shape for this method to work, not a lot of flat spots or rust on the galvanized pipe. Here's a link: www.plumbingsupply.com/bronze-compression-fittings.html
Pipe was directly under the broken sprinkler head. If your leak is on a sprinkler zone you just have to turn off the timer to keep the zone from running. If the leak is on a supply line you'll have to shut off the stop & waste valve or main valve for the sprinkler system.
Very Good but what happen if I have a very bad rusted galvanized pipe? The galvanized pipe is in the soil and it is wet and rusted; therefore s in bad sharp. Still searching in google on what are the options? 1) try to remove joint 2) cut 3) compression connection. Thanks Tony
Galvanized pipe is not easy to work on. 1. If the pipe is paper thin, has flat spots and is weeping water, you'll have to replace the pipe. If this is the case I would transition from galvanized to PVC. 2. If the pipe has some rust but is still round; you can remove the rusted areas, clean up the pipe, cut the pipe and use an IPS dresser coupling on each end with PVC pipe between the dresser couplings. 3. You can try to undo the pipe at a fitting but often times the pipe gets so rusted that you'll break the pipe off in the threads.
If the galvanized pipe is paper thin and has flat spots to where you can't get a dresser coupling to work or thread the pipe, there's not much you can do except to replace it.
Thanks for this, I was about to go rent a MIG welder. I may try this first. Appreciate it. Gotta love the UA-cams for people helping people!
I was in a panic when a similar pipe failure happened. Your calm voice settled me! Thanks!
@chargermopar
Sounds like you have a good system set up. I like the funny pipe and PVC fittings just for ease of use and time constraints.

Welding the pipe to repair it is a novel idea. Not sure if a welder would work if the pipe is old and corroded.
Thanks.
How long after this "fix" did it crack where the female adapter threaded into the galvanized?
Have you done the gas pressure calculations to determine whether you will have sufficient pressure at the dryer?
Regardless, given the potential "boom" factor for getting it wrong, I'd hire a plumber for this one.
You wanted to say "volume", not "pressure". Gas "pressure" is same throughout the house
@chargermopar Is it possible to do this same repair using galvanized pipe instead of pvc?

Can this system be used on shower valve replacement to original galvanized 1/2 inch pipe ?
Always prime PVC prior to gluing. Also should have used clamps on funny pipe conection
Funny pipe doesn't need clamps, just shove the funny pipe past the last barb and you're done.
why not just add a female to female coupling, then thread in a male to solvent pvc socket then PVC the rest

Nice work but how did you know where to locate the pipe? I found the leak but how far away would the shutoff valve be?
Pipe was directly under the broken sprinkler head. If your leak is on a sprinkler zone you just have to turn off the timer to keep the zone from running. If the leak is on a supply line you'll have to shut off the stop & waste valve or main valve for the sprinkler system.
@@Iscaper ty I appreciate that. So we found the valve and its frozen. Next step is call a pro.

Pex is ur friend
์Nice video. My plastic pipe broken!! -''-
Thanks Icetea for watching.
Kerry do you do the same thing when you have to tie into the water. Main to the house for a sprinkler sys if so do you trust dresser coupling for psi
If the line to the house is galvanized I usually try and use a brass dresser tee.
What do you do is the pipe is really rusted???????
If the galvanized pipe is paper thin and has flat spots to where you can't get a dresser coupling to work or thread the pipe, there's not much you can do except to replace it.
You didn't show us the most important part of this repair: How you cleaned and threaded the other end of the galvanized pipe.
Other end of the galvanized pipe is not threaded and gets a dresser coupling.
Repairing galvanized pipe is the worst!
