Is plastic vent piping acceptable for new dryer installations?

The use of plastic vent piping for new dryer installations is not acceptable due to safety and performance concerns. Dryer venting needs to be done with materials that can withstand high temperatures and resist the buildup of lint, which can pose a fire hazard. Metal venting materials, such as aluminum or galvanized steel, are recommended because they are durable and can effectively handle the heat generated by dryers.

Additionally, plastic vent pipes can deteriorate over time when exposed to the heat from the dryer, leading to potential failures or blockages. This can create risks not only for the dryer’s operation but also for home safety.

While there may be specific cases or allowances in certain codes for plastic in low-risk scenarios, standard practices in most building codes and installations prioritize metal vent materials for dryer exhaust, making plastic generally unsuitable for this application.
