Anyone know of a "temporary" fix to a leaking GF joint/fitting? (No I cannot use a furnco fitting...its a 6" Tee)

tee itself. a reducer in the tee is leaking.

Can you get the pressure off it ?

What is contained inside the tee?

What is the pressure inside the tee?

If you can get the pressure off the tee for 1/2 hour to an hour, you can rough the area, dry it, and use epoxy and a heat gun to seal it.

Its a type of pipe for chilled glycol lines. Its fused together and not very easy to deal with...

its a new install, not wet yet. I just want a way to patch it until we can get the parts to fix it properly. this way i can pressure test (I am under a tight deadline until startup...no time to waste)

gotcha. well that's way better than having the store open and glycol raining from the ceiling. I like PHM's idea then.

OK then -

Is it a crack in the structure of the pipe / fitting?

In which case I would drill a small at each end of the crack. Say; an eighth.

Or is it an unbonded socket joint?

In either case I would clean and rough up the surface all around the leaking area. A wire wheel will work well.

Use J/B Weld or PC7 to coat the area well. You can accelerate the cure from 24 hours to about 1 or 2 hours with some heat. Just barely 'too hot to grip' is a good temp - call it 120-125 degrees F.

Pretty much any epoxy will work - even that roll-in-your-hands stuff that plumbing houses sell The plumbing house stuff cures in a few minutes too.

Check the specs if you don't believe me.

if it's only to pressure test and you're waiting for a new fitting, try some epoxy or some jb weld type stuff, and possiblt reinforce it with some large hose clamps I know this sounds totally ghetto but it may be able o finish your pressure test ld your test press to find other leaks i dunno if it will work but it my hold what e you going to use as test pressure? 90#?

edit, aprently i didn't read PHM's post, lol

Hey, I dont mean to be a buzz kill, but Georg Fischer does not want you to use JB Weld or PC7, talk to them after I saw this theard and if they dont Recommend it they wont warranty the fix. I'm attaching a Pdf on repairing this leak. They tell me they know of this store and ask you call 905.792.8005ask for Kuno( GF Canada) If you have a picture I would love to see it.

I worked with GF pipe and love it, installs are quicker(after our first one) Hate insulating the pipe though. I hope this PDF works

I know that this is not a permenant repair for the leak, but correct me if i'm wrong but in this case there is a job that needs to be completed in a set time. There is a pressure test that is required to be done and this leak in question is preventing the completion of the pressure test.

If a temporary repair can be made on this leak only to help preform further leak on the rest of the system that should be acceptable in the real world.

this repair will NOT to be left in service and will be replaced once the proper parts arrive to the jobsite which is no where near a GF parts supplier

according to prpper procedure another pressure test will be needed to be done on the system again after the "T" fitting is replaced and before the system gets wet to be proper, :)

Nothing last longer than a temporary fix...

Yea, if youre not able to get that 6" T for a few days and it holding you up only durning the pressure test stage, you could try. Not sure if JB Weld would work?? The problem is if it on the 6" thats the main supply or return line so hard to work aound.

Is this a factory leak???:

Thanks guys. Hill has been great with the problem (on it like white on rice).

I do have a bit of a time constraint with this install but that just makes it all the more interesting. I am going to wait until Monday or Tuesday before I attempt to make an attempt on a patch.

I am not as concerned with the leak at this moment as it may have come across but it has made me think about what I would do if I ever have a leak on a part of the GF once I am in operation...

One of my fears as well... Even if you have a coupling on site you still have to wait hours for the glue to set according to GF.
