Corrosion on furnace exhaust pipe. Corrosion is one of the major problems due to which automotive exhaust components have a limited lifetime as it is basically attacking the muffler since long ago. Pipe gravity and the cooling of the flue-gases you can make the pipe too long. Flues can crack due to corrosion. If your vent pipe is single-walled you must create a 6-inch gap instead. High humidity and moisture can play a part as can a lack of venting of exhaust gasses in your furnace. In a great majority of cases plastic piping is used to vent high-efficiency equipment. Use a longer piece of aluminum sheeting so you can create a larger perimeter. Per several peoples suggestion I had a chimney repair company come and inspect the chimney.
This high efficiency venting system must be installed when you install the new furnace. In case you missed it you can see it here. Flues can crack due to corrosion. Per several peoples suggestion I had a chimney repair company come and inspect the chimney. Any added product would burn off the exhaust pipe but the oil pipe junction doesnt get nearly as hot. Pipe gravity and the cooling of the flue-gases you can make the pipe too long. Rust and corrosion create leaks that.
Leaks in the vent pipe have more dire consequences that demand immediate attention. It is classified as Type BH venting. If not you can follow these three steps too fixed the water dripping from the furnace the same day.
Working on our 133 year old house I found the furnace exhaust pipe rusted out. These PVC pipes are connected to the furnace and expelled outside. There will be a point where these factors counter-balance the momentum of the flue-gases. A review of the different types of corrosion is often helpful in initially determining the likely corrosion cause. Water with a pH below 7 is generally considered acidic and below 65 water is corrosive to most materials. Flues can crack due to corrosion.
