Drainpipes connect directly to a main or secondary stack or joined to a re-vent that travels up and across to a stack vent. If you didn't have vent pipes, the wastewater going down your drains would empty your traps because of a vacuum effect. When this happens, toxic sewer gases can seep into your house.

With insufficient ventilation, warm air lingers in summer, which can lead to overheating and the need for more cooling. In winter, a lack of ventilation can allow cold air to enter, requiring more heating. This results in a higher energy consumption for both heating and cooling, and consequently higher energy bills.
It's important to remember that static vents serve a purpose, especially in older homes. They provide ventilation to indoor spaces, help regulate indoor temperatures and prevent the build-up of excess moisture in wall cavities and rooms which can lead to mould outbreaks and damage to building materials.

Installing an HRV or ERV system that has its own ducts can be the most efficient way to ventilate a house, especially if no ductwork exists. The HRV or ERV heats the incoming air, and its internal fan distributes the now tempered fresh air and draws the stale air through its own dedicated ducting.
