Actually, Michael, I know my options ... I just wanted to see if the silicone was a viable one .... thanks for "reading my intentions" tho ... I thought maybe there was someone that has had this issue with a vent pipe... Since you were in construction, it is a short span from the roof to the floor of the attic ... not a whole lot of flexibility there I am guessing ... could i use a Fernco on the down side?
I would question a "vent" with that much water "vapor" what is it venting and how hot are the gases? Does it have a cap on it or could you use two 90 degree elbows to put a cap on it?
It doesn't have a cap on it ... It is the main vent for the master bathroom .. I am ignorant with this stuff, so if I am thinking wrong on it I am open to education ... it is a 3" PVC pipe coming straight out the roof ... I am thinking that the rain water and condensation are supposed to just go into the main drain in the basement?
A fernco would cost more Can you post a pic. If everything is sealed right you maybe just getting condensation on the outside of the pipe. Which is a cheap easy fix Sent from my LG-E739 using Tapatalk 2
There is no primer visible, so I'm guessing its just pressed together. The "T" was installed up side down for a vent. And if its a gas vent for a bath room the the "gas" is room temperature and has no reason to condensate any noticeable moisture. Some thing else is amiss, or the roof is leaking.
John, I agree with the no glue .... I was just up there and I believe you are right .... AZ far as the condensation ....it does not happen other than in winter when it is cold out ... so room temperature air meeting the winter air = condensation ....
Is there a way to vent it under the eve and out the sofit? That would prevent the condensation from running down the pipe. A smaller diameter pipe would also have less surface area for condensation to a mass, and allowing the pipe to clear the roof by several feet would give the gasses more time to normalize with the outside temperature thus creating less moisture.
Here's the thing ... if it was sealed correctly, the condensation and rain water would ALL go down into the sewage pipe and out of the house .... I am not a fan of venting anything out of the soffits ...
Tony, let me make sure I am understanding your situation. You have a vent pipe for your sewage plumbing and there is a condensation pipe for the A/C unit that connects to it in the form of a T fitting? Is it condensation build up that is running down the pipe or is the T fitting leaking that the condensation pipe is going into? If it is the fitting, you should replace it. If a Firmco will work, try it and give it a day or two. If it does not leak, let everything dry up and insulate it. If I am understanding the situation correctly, reason for the condensation in the first place is the drastic change in temp between the inside if the pipe an outside. Using insulation will essentially expand this area and make a less drastic change thus reducing or completely eliminating condensation at all. If I misunderstood the situation that is null and void. I personally would not use Silicone. For one, the surface has to be really clean an dry for silicone to work properly. I imagine it is neither. If the T is leaking, the silicone cold hold for a while then reroute the water possibly causing a less visible, worse condition over time. Since I can't see it, it makes it a little harder to say one way or the other. What I do know is water can have some strange travel routs and cause a whole lot if damage before discovery of the problem. As a former remodeling Forman I have seen some wicked stuff water can do and even crazier travel paths. Bottom line, if it is possible to replace it at all, that would be best. Patching something like this could lead to more serious issues in the future. Goo luck with it. I feel for you having to repair that in the small confines of an attic space. I'll pray you keep your sanctification and salvation on this one brother!
No problem PT. The T is upside down but out is not a important for air flow as it is for water. You got it now go hunt:D Sent from my LG-E739 using Tapatalk 2
