Plastic dryer vent hoses are prone to crushing and obstructing circulation, which can cause the dryer to overheat and lead to lint fires. It is recommended to replace plastic dryer vent hoses with metal ones, which are safer and more efficient. The process of replacing a dryer vent hose involves disconnecting the dryer from its power source, pulling it away from the wall, disconnecting the old hose, and connecting the new one. This includes securing the hose with pipe straps and screws, ensuring it is free of kinks and bends, and covering all seams with foil tape.

What You'll Learn

Disconnect the dryer and pull it away from the wall
To replace a plastic dryer vent hose, the first step is to ensure your safety. Turn off all electrical outlets and unplug the dryer. If you have a gas dryer, be cautious and do not forcefully pull on the gas line.
Now, you can begin to pull the dryer away from the wall. This will give you more space to work comfortably and safely access the vent pipe. If your dryer is in a tight space, take care not to disconnect the vent hose or damage the gas line as you pull it out.
Once you have moved the dryer away from the wall, you will have better access to the vent hose and can begin to disconnect it. Loosen the band clamp securing the hose to the exhaust outlet using a screwdriver or nut driver. Gently pull the vent off the outlet.

Remove the old hose
To remove the old hose, start by unplugging your dryer and moving it away from the wall. This will give you more space to work and easier access to the vent pipe. Ensure that all power switches are turned off for safety.
Next, you will need to disconnect the hose from both sides of the connection. Loosen the band clamp securing the hose to the exhaust outlet using a screwdriver. Remove the clamp and set it aside. If there is any old foil tape, make sure to take that off as well.
Now, carefully inspect the hose to ensure there are no significant tears or crimps. If the hose is in good condition and you plan to reuse it, set it aside. If not, you can dispose of it or cut off the broken end to reuse the rest of the hose.
Finally, vacuum away any lint from inside the dryer and the surrounding area. Lint buildup can be a fire hazard, so it is important to ensure a thorough cleaning before installing the new hose.

Measure and cut the new hose
Before you measure and cut the new hose, make sure you have the necessary tools and safety equipment. Wear gloves to protect your hands and, if necessary, safety goggles. You will need a utility knife or tin snips, duct tape, hose clamps, and a measuring tape.
To measure the new hose, first determine the amount of hose required to connect your dryer to the exterior vent. Mark the cutting point with a measuring tape, based on your measurement. You can use a marker or a piece of tape to mark the spot. If you are installing the vent through a finished wall, you will need to remove a small section and check that you are not cutting through any wiring, plumbing, or ductwork.
When you are ready to cut the hose, use a utility knife or tin snips. Cut the hose at the marked point, ensuring that you cut as straight as possible. Tin snips are best for a cleaner cut, especially if the hose has wire support. If you are cutting rigid duct pipe, the edges will be extremely sharp, so be careful to avoid injury.
Once you have cut the hose, you can attach it to the dryer and vent. Slide a hose clamp over each end of the cut hose and attach one end to the dryer's vent connection. Secure it with the clamp, then do the same with the other end at the wall or window vent. Tighten the clamps enough to hold the hose firmly in place, but be careful not to over-tighten, as this could damage the hose.
Finally, seal the hose with duct tape for additional security and to prevent leaks. Wrap the tape around the outside of each hose connection.

Connect the new hose
Before connecting the new hose, ensure that the dryer is unplugged and disconnected from its power source. Pull the dryer away from the wall to give yourself more room to work.
Now, you can begin connecting the new hose. First, attach the hose to the dryer. Slip one end of the hose over the dryer's exhaust port. You can use a dryer tube clamp or a piece of foil tape to hold it in place. If you're using a clamp, unscrew it to loosen it, slip it onto the hose, and then tighten it back up. If you're using foil tape, simply wrap the tape around the connecting seam.
Next, attach the other end of the hose to the vent hood. Slide the top of the hose over the vent hood's cap extension. Again, you can use either a hose clamp or foil tape to secure it. If using foil tape, just wrap it around the connecting seam. If using a hose clamp, remember to first unscrew it to loosen it before slipping it on, then tighten it back up.
Finally, secure the vent hose with pipe straps. Make sure the hose is free of kinks and bends, then fix it to the wall using screws and pipe straps. Use one pipe strap for every 6 to 8 inches (15 to 20 cm) of hose.

Secure the new hose
Securing the new hose is a crucial step in the installation process, ensuring the safe and efficient functioning of your dryer. Here is a detailed guide on how to secure a new dryer vent hose:
Secure the Hose Connections:
Before securing the hose to the wall, ensure all hose segments are securely connected. Vent hoses have seams along the edges that snap together. Press these seams firmly against each other along the entire length of the hose. If using elbow pieces, insert the crimped end of one elbow into the hose. For joint pieces, use an aluminium duct connector to join the segments. Wrap foil tape around the connecting seams to hold them together and prevent leaks.
Attach the Hose to the Dryer:
Slide the bottom end of the hose or the lower elbow piece over the dryer's rear exhaust port. You may need to loosen the band clamp securing the hose to the exhaust outlet using a screwdriver or nut driver.
Secure the Hose to the Wall:
Use pipe straps and screws to secure the vent hose to the wall. Stainless steel pipe straps are recommended as they are more durable than plastic straps, which can dry out, crack, and break over time. For safety, use one pipe strap for every 6 to 8 inches (15 to 20 cm) of hose. Ensure the hose is free of kinks and bends before securing it.
Test the Installation:
Once the new hose is securely attached and all seams are covered with foil tape, you can run a test cycle on your dryer. It is recommended to run the shortest cycle and keep a close eye on the dryer to ensure the new hose is functioning properly.
