 Your home has different types of exhausts. There is for the furnace if you have a chimney, a kitchen fan or a dryer vent. There is also the plumbing vent stack that does not get too much attention unless the winter comes and it freezes shut. This may make flushing the toilet harder!
To protect you in winter, here are some of the things you need to know about this vent: What does it do? The main task of the vent stack is to let sewer gases to harmlessly vent through your roof. This is mostly made of a cast iron pipe but in newer homes, this can be made of PVC. Most homes have one stack, and the drain lines are mostly connected to it. The drains in your home that includes the tub, sinks, toilets and the likes have a trap that works like a plug to maintain the sewer gases from escaping from the drain. The use of a plumbing vent is to maintain the air pressure in the drain system as normal as possible so that the water will not draw off out of these traps. What can go wrong? Plumbing vents are mostly ignored during the rest of the year, but during cold weather, homes may need to look into. But can plumbing vents freeze? In extremely cold, water vapour in the vent can accumulate and thus freeze on the top of the stack which may close it off completely if ignored. When this occurs, the drain system will be disrupted that will result in having an awful smell. Even if the vent does not freeze completely, this may cause toilets to have trouble flushing or it could also affect the other drains in the home. When this happens, make sure to contact your plumber so that they can fix your vent right away. Do not ignore this because the gases that can build up in your home is not safe aside from having that bad smell. Comments are closed.
