After i had access i ran the vent hose under the attic insulation and installed a vent in the.

How to unfreeze an outside air vent roof.

To provide both of these functions terminating the drain vent high up above the roof is necessary. Terminating these pipes above the roof ensures any vapours that potentially come up through the drains from the sewer will harmlessly be released outside rather than penetrate our indoor air. Over time these vents can become squeaky from moisture and age related natural degradation. Designed to maintain steady ventilation to attics these devices are necessary to prevent mold and excessive heat buildup under the roof.

The hot moist air would travel up the vent hose towards the roof and condense in the cold attic. Under normal operation the air to relieve that vacuum would come from air flowing down through the roof vent. Firstly the pipe freezes at the roof outlet due to condensation of the warm gases as they reach the cold outside air condensation continues until the pipe finally freezes right over. Clear your roof of snow on a regular basis.

Plus in the cord on ground level for a few hours. But now the roof vent was frozen and could not supply the air needed to eliminate the vacuum in the sump. If this happens pour warm water down the roof s sewer vent stack. There was no access to the attic until i had the wood stove installed.

Then the vent pipe may be re angled and a new cap may be put into place to keep debris from clogging it again. A gurgling toilet may indicate a clogged or frozen vent stack. There may be a clog in the sewer line right where it meets the vent pipe. This blockage keeps air from traveling up the vent pipe properly.

Here is the update video on this pipe https www youtub. Excessive snow on the roof can block the vent s stack and cause freezing. Turbine vents are those ubiquitous devices found on almost every residential rooftop. As we know from basic physics nature abhors a vacuum so the air supply for the vacuum in the sump had to come from somewhere else.

And when the need arises. I also used to climb up on the roof and thaw the vent with hot water.
