I have a bi-level ranch, just moved in, first house so
excuse any mis-terming of items.

In the 2-car garage, the main sewage drain pipe that is
angled into the ground always drips (slowly about every
15 seconds) whenever it rains, no other times at all.
The pipe seems to have 2 others connecting to it, from
the right & left. I can't cut the sheetrock to get a
better view of the vertical dripping because there is a
horizontal wood beam blocking my view of the drainage
pipe if I were to stick my head up into the ceiling
sheetrock.

I checked the attic while it rained hard and there are
no obvious leaks and all the roof openings are bone dry
with cobwebs around some of them. My house also has 2
overhangs, both sloping away from the house along w/ the
gutters which are leak-free.

The only culprit I can think of is that for some reason,
the vent pipe sticking out of my roof (not from the
furnace, that one is covered), collects water whenever
it rains and that water finds it's way out of a perhaps
broken seal or something somewhere and it hugs the pipe
down into the garage. Because the roof water vent pipe
seems to be directly above the problem area in the
garage...I was going to try 2 things to fix this even
though I'm not sure where the drip starts from:
1. Cover the vent pipe (not sealed, just to prevent rain
water getting in, but air will still get in/out)
2. Water sections of my roof/gutters with a hose to try
and re-create the leak and figure out where it is coming
from....

Any other ideas? Unless of course it is somehow coming
from where my raised deck is bolted to the side of the
house, but I find that to be a stretch of the
imagination....

Thanks!!!


Ok, so I found the leak I referenced in my previous
post...but the problem is, it only occurs when I run a
hose INTO the plumbing vent pipe, the flashing & rubber
gasket AROUND the pipe are in perfect condition.

So my question now is....everywhere I read states that a
plumbing vent pipe should NOT need a cap. Given that
mine leaks when it rains and/or I run a hose into it,
can I get away with just capping the pipe (obviously not
restricting the air flow)? Or do I have much bigger
problems than that? It does not drip when we take
showers or use water in the house, only when it rains...

Tnx!

You can try a simple way to prevent rain entering
by adding a 180 deg "Return Bend" to the vent terminal:

If rain water really is wicking out of a joint, it
could be sealed with more PVC cement or even RTV.
It's not critical since it's not under pressure.
I don't think I'd attempt taking the fittings apart
as you'll likely end up with a much bigger project...

Thanks, I was going to go to Home Depot to see if they
had something like that. I looked down the vent pipe in
the attic, can only see about 2 feet down though, but it
looks like the morons who renovated the bathroom (I just
bought the place a few weeks ago), seemed to have driven
at least one nail (because I can see it), and I'm
asuming a few more, into the vent pipe because the
bathroom sheetrock is right next to the vent pipe. The
schmucks must have thought it was a stud or something,
who knows...So I'm sure that the vent pipe must be
leaking around a puncture wound somewhere in the house
and I'm not planning on ripping apart my house to find
out where (I wish I had one of those snake light
camera's like they use at the pyramids).

Since it doesn't seem to drip/leak when I use my
plumbing fixtures, I'm going to assume that the leak
starts somewhere ABOVE all the joint areas and hopefully
a nice long-term remedy will be that 180 deg "Return
Bend" as you suggest. I guess the worst thing is that
I'll have a tiny bit of air escaping from the vent pipe
into the house, but I assume it won't be enough to cause
problems with smells & things like that.....

Sound about right on all this?

As long as when you run the water into the vent from the roof and most of
the water goes to the drain, you are ok, if the vent is filling up then
overflowing from the hole into the house, you have a seperate problem and
need to clear that clog as well.

If it does drain, the leak is probably at a bend where the pipe runs nearly
vertical for short distance.
