fixing a leaking vent pipe joint

So one of the vent pipes in my home is leaking down onto the top of an interior wall. Apparently rainwater or condensate is collecting at the fitting and is leaking out of where it was poorly put together (at a tee fitting).
Not wanting to remove the entire T fitting, it seems like the best way to fix this would be to cut the problem pipe and ream out the portion in the fitting. Then replace with a new section that is properly glued in place.
Is there a better method?
Are there reaming tools available? I would assume so, but don't see any at the big box store web sites.

They have reamers for anything from 3" down to 1/2 ".
Best investment I ever made as it helps anywhere that a tough pipe repair is the job.
They work well enough to be used in pressure systems too.Call around some of the bigger pool supply houses and you'll find what you're looking for...
I live in Palm Beach Florida so,their all over,your mileage may vary if U live in Minnesota or somewhere where in-ground pools are scarce.
Hope this helps..
U my friend,need to visit a pool supply house.

I have now used it to seal the screen doors in both my rowboats, and my friend has used it on the double screen doors in the hull of his yacht.
Buy a can of this stuff!
If it is a vent pipe the water is probably not coming from inside the pipe. If it is rain water coming in then you need to look to the roof penetration.

There are pvc reamer kits available from any electrical supply houses too. Very expense for a one time thing.[xx(]
Seal it up with something on the outside of the pipe, no pressure in there, and there should NO water either UNLESS it was designed as a
"wet vent" which is not the best thing to begin with.

It appears to be coming from inside the pipe. No signs of water anywhere else along the stretch from the roof. It's just a small amount of water at this particular junction, and the leak is coming from the joint in one pipe to the T. One side of the T is leaking and the other is not. As I said in the initial post, it is either condensate, rain, or both.

Yes,...I know that's not a proper repair, but it will most likely work just fine, even if you only use it for a temp repair.
flex seal phil swift can;t be wrong ya know handy man in a can[:D]
That spray stuff fixed my leaking gutter joint.
If it's a tiny leak, and not under pressure you should be able to swipe the side of the joint that's leaking with the blue 'rain or shine' pvc cement and stop it.

However, I wouldn't discount skicat's post too quickly. Tape some newspaper around the pipe well above the tee fitting then hose down the roof around the vent for a few minutes and check the paper and the joint again.

Will do, but as I said no evidence of rain intrusion from around the roof (the vent pipe goes through several areas where it would be noticeable) and there is no sign of any calcium or other water deposits up further. But yeah, that test wouldn't hurt.

If you are sure the water is coming from inside the pipe, I would do as Marc1301 suggested. Those pipes are supposed to be sloped to prevent water from ever accumulating in them. If that tee is on a horizontal run where rainwater might collect then you may want to throw a level on it to be certain of the pitch if accessible .
the pipe is properly sloped, but it appears the lack of seal is on the low side of the joint so anything that runs down through it is seeping out. There's plenty of trace elements from the evaporated water deposit right around the leak, so it would seem that it would be obvious up higher.[:I]

BTW: Your sewer vent system should NEVER get water/sewer in ti..
If it was the sewer water,it would be coming up in your tubs,showers,sinks etc.before it got to any vent.
Pay no mind to the guy that has been using pvc pipe,DAILY for 35 years...Except most weekends..

As I said, I think this is rain water coming in at the opening above the roof. Since there is no cap on the top it's more than likely that this is the source. But it could be condensate too. The leak is up in my attic space.

If you had sewage at that level, I sure the heck wouldn't want to be in your house right now![xx(][:D]
I never ream pipe out of fittings with PVC. I find it easier to cut the pipe flush with the hub, make a minimum of 2 cuts through the inside of the pipe being careful not to cut into the fitting, and then use several small flat bladed screwdrivers to wedge the pipe pieces away from the wall of the fitting hub. To make it more difficult to fracture the hub on the fitting I put a band clamp/hose clamp around the hub and crank it tight. PVC cement is brittle and will often crack away very cleanly. Sometimes shards are left stuck inside the hub and need to be cleaned out with a sharp chisel or even a utility knife. This technique does not work with ABS black pipe.
Another possibility to check for is if it was ever glued in the first place. Sometimes guys will dry fit things and forget to go back and hit it with glue. If it was a forgotten joint then just pull it apart hit it with some primer and glue and stick it back together.

Good to know. This is black ABS.

I believe in the belt and suspenders approach, particularly if you're not going to do the job the exactly correct way.[:D]
Tomorrow, once it's light, I'll hose the roof down and check for any leaks up there.
