Just be careful when you get up walk crawl around in an att.
Drips from stack in attic.
When water condenses and drips into your attic or home it can cause a some serious secondary problems.
Like during the heavy rain and you notice a dripping sound from the attic and found a dripping water allegedly from roof vent leaking.
Transition coupling either plastic like this or banded rubber to join a 3 in.
I found the two pvc pipes coming out of the unit along with a copper pipe that has quite a bit of air flowing out around the opening.
Why is this a problem.
Dealing with roof vent leaks during heavy rain can be very challenging.
How to deal with a leak in the attic.
Water could get into the attic or above your ceiling and either drip to the floor or roll along the stringer the long piece of wood that spaces out the roof trusses and runs the length of your house.
You can t call a roofer to come and you can t even try to climb to the roof to find the cause and fix it.
First water dripping off of your ducts and onto your insulation can cause the insulation to compress which decreases it s r value or ability to insulate.
Sometimes vents like this had to be.
Any ideas would be greatly appreciated.
Humid air was feeding frost on all cold surfaces.
Fortunately the cold snaps were not too long or frequent and the insulation dried out by summer.
Someone took a shortcut.
However neither one of the pvc pipes have a t to open and try and unclog.
When the forced air unit is in the attic sometimes the condensation is drained into a normal interior drain and a second outside drain is used for overflow.
Is unusual although it may be required by your local plumbing code.
The frost in the attic was thanks to poor sealing around the stack chase all the way from the basement up to the connected attics.
If the evaporator unit is in the attic then the line carrying condensed water may also be in the attic and this line may also proceed horizontally in the attic to and through an exterior wall and then terminate outside that wall where the condensate drips.
First of all going from 3 in.
So water is condensing on your ac ducts.
Attics can suffer two types of leaks.
Why is condensation on ductwork a problem.
For example your roof might have a leak through the attic vent or roof shingle at the top.
The overflow drain is in a visible place so you know that the main drain isn t working and you can fix it.
It would be very dangerous to do.
The condensate line may be copper or may be plastic.
