Working on finding those black plastic insul-vent covers but no luck here locally and tough to find online. Both of my vents have elbows and horizontal runs in the attic so unfortunately it sounds like the copper t won't work for us. Plan will be to just fill all the traps after using the shower/toilets for a couple days until it warms up. Well both of mine have a lot of frost built up, not sure if they are completely plugged yet or not but with a fresh coating of snow I am not headed back up there to open them up. Someone asked about making one out of pvc painted black.won’t work.ĭo this and there will be no more discussion on the subject needed!
With this that 3 foot of pipe sticking in the heated space as well as the warm sewer gas at that level heats the copper pipe and because copper is such a good conductor of heat it keeps the copper in the cold section of your vent warm enough to stop the frost build up. So you would need that copper t to be 8’ long. You need the copper to be 18” + 4.5’ + about 3 ‘ extending inside the vent pipe below your ceiling level (inside the heated space). Let’s say your vent sticks above your roof line 18 inches and inside your attic it is 4.5 feet from your roof line to your inside ceiling that the vent pipe penitrates up through.
You simply don’t get enough heat transfer from the sewer gas to the copper to do any good when it is very cold. How can we expect a piece of copper maybe sticking in the vent pipe a couple of feet to keep the vent open when the sewer gas it self is frosting up. The copper heats up some by the warm sewer gas but your attic should be close to the outside temp then you have a foot or two of plastic vent pipe sticking above the roof. SLE, your t, how far does it stick down into your vent? A copper t like most I see being sold will not do it in this cold weather! Period.
