Yes, you absolutely can (and generally should) hard pipe a dryer vent. In fact, building codes typically require smooth, rigid metal ducting (hard pipe) for any concealed vent runs that travel inside walls or floors.
For clothes dryer venting, a 4-inch, rigid aluminum or galvanized steel duct pipe is a better option. They let air flow more freely and reduce lint buildup.
Dryer venting tips and practices
Flexible transition hose between the dryer and the wall outlet should be either the foil type or the aluminum flexible duct (most preferred). Do not use the plastic or vinyl. Concealed ducting must be rigid metal (galvanized or aluminum) duct.
M1502.
The maximum developed length of a clothes dryer exhaust duct shall not exceed 35 feet from the dryer location to the wall or roof termination.
In summary, while flexible accordion piping may seem like a convenient option for dryer venting, a hard pipe provides better airflow, fire safety, durability, and aesthetics. Investing in a hard pipe may cost a bit more upfront, but the long-term benefits make it a worthwhile investment for any homeowner.
Yes, mice can easily squeeze through dryer vents. Rodents are attracted to the warm air and lint, and they can pry open standard plastic flappers or squeeze through any cracks.
* Text: "RIGID METAL. These are least likely to sag. " * Recommendation: Rigid metal ducts are the best choice for dryer venting.

In the United States, most home inspectors refer to the International Residential Code (IRC) M1502 for dryer venting. However, some states may have additional regulations. The International Mechanical Code (IMC) 504 also includes extensive clothes dryer requirements.
Foil tape is the only kind of tape meant to withstand the heat dryer venting delivers during a cycle, so don't settle for alternatives like duct tape. Avoid using screws or anything that would protrude into the venting to secure the hose, as lint quickly snags on screws and can build up over time.
Of all of the dryer duct materials, rigid metal ducts catch the least amount of lint. Rigid metal ducts are more expensive than other types, but they are durable and efficient.
Yes, a dryer vent can have a 90-degree elbow. In fact, they are commonly used for tight spaces behind the dryer. However, they reduce the maximum length your vent can run because of restricted airflow.
Dryer vent tape is specifically designed for high heat and ensures a secure seal. Duct tape is not safe for dryer vents due to fire risks and adhesive breakdown. Foil tape is a recommended alternative for sealing dryer vents effectively. Regular maintenance of your dryer vent system can prevent safety hazards.
The choice between flexible and rigid dryer vents depends on your specific needs: For short, straight vent runs – Rigid metal vents are the best choice for safety and efficiency. For tight spaces with multiple bends – Flexible vents may be necessary but should be used cautiously and cleaned regularly.
From 19 January 2027, vented, condenser, and gas-fired tumble dryers can no longer be sold as new products in Great Britain. Only heat pump tumble dryers meeting the new minimum energy performance standard will be permitted for sale.

For a safe and durable dryer vent connection, you should use both metal worm gear clamps and foil dryer vent tape. The clamp secures the hose to the wall and dryer, while the foil tape provides an airtight seal that prevents lint and hot, moist air from escaping.
PVC is plastic and not conducive for dryer vents. When lint travels through a PVC pipe, static electricity created by the plastic will pull the lint to the sides. Over times this causes a 4” pipe opening to shrink dramatically. This leads to poor airflow which creates drying exhaust issues.
