As a retired general contractor, I've used the (flamable) Flex-tape, with screws, and regular gray tape for various clients. I'm redoing my dryer exhaust for my home. I came across your short film which was very helpful. Back in the day when I was working, home owners wanted the cheapest way out, period. The alternative to flex hose was 4" hot water exhaust metal pipe. Only one in ten preferred to pay the additional few dollars for a better system. Thank god no one I did repairs for ever had a fire. Thank you again for good info!

I thought you might like to know that I have watched about a dozen different videos that offer tips and tutorials on dryer vent systems. This video is by the best that I've seen. It was straight to the point and you covered all the most important information without rambling on or providing unnecessary info. This is the video I was looking for. I appreciate you taking the time to share this info with us and I look forward to installing my new vent system the right way. Thanks again!

Thanks for the excellent information. Sadly lots of places use the crappy slinky flammable dryer vents. Also thanks for the tip on no screws and the aluminum duct tape.

This is so helpful! I’m so thankful for you to be sharing this important information.

This is probably one of the best dryer venting videos out there. I do want to mention that most codes dictate dryer vent runs to be no more than 25 feet, and for each 90° turn you should subtract 5 feet less than that.In other words if you have 2 90° turns in the venting the total run should be no more than 15 feet. But this is a great video.

This is so helpful for me. You explained all the important information I need to know about replacing the old dryer vent. Thank you so much.

Wow Thank you ,I’m a new home owner and everything thing you’re talking about with slingie duct I’m experiencing my inspector didn’t catch this during my home owners inspection 😡Thanks again for the good information 😄

Wow, thank you! I actually did everything you recommended because I focus on quality.... But I never realized the importance... Glad I inadvertently did it right!

I didn't know about the flammable material or about non-installation of screws. My vent run will have to go into the 3 ft crawlspace and vent outside at the lowest part of the house. Thank you very much for the concise information. I've subscribed. Perhaps I'll continue to learn from your instructions. Jose

You have cleared up so much I was needing to know. I worried about the fire hazard for sure. Thank you.

thank you so for the information, we had the flexible slinky duct installed in our townhome and a dryer flex just laying around the house. We quickly switched! thanks again!

This video is the best I’ve seen on the subject!! Thx

Very helpful and easy to understand video. Thanks!

This was a very helpful video, thank you so much 😊

Thanks for this video. Very helpful!

Thanks for creating the vid and your positive contribution to the youtube community. In your installation do you believe it prudent to install a dryer booster fan considering the long, seemingly, long run of duct?

Excellent presentation and information. Thank you for doing this!

in the attic you can see you ran your rigid duct in the wrong direction, your joints should fit into the downwind pipe, you do not get lint caught in the joints that way. it also minimizes turbulence in the pipe and gives better airflow.

Thanks for this. Very helpful.

I like the 90 degree elbow and took that from your video and ordered one. Not sure why you were calling the solid 4 inch vent aluminum as it is steel but it is what it is.

Thanks man I'm hooking up my dryer tomorrow

It's amazing they let homebuilders get by with this. My dryer caught fire via faulty thermocouple that let the element get to hot. The gentleman doing this vid is ABSOLUTLY CORRECT about the cheap foil vent, It will catch fire because once a dryer catches fire those vents act as a chimney pulling the flame into the vent itself . Thank the good Lord I was able to jerk the burning foil down while my wife beat out the flames with a wet towel before our house caught on fire because my venting was about a 20' run across my basement ceiling but was trying it's hardest to catch the insulation of my house subflooring afire .My hands got badly burned a blistered in the panic, flames were coming out of that stuff like a flamethrower . Had that been vented through the attic the unthinkable may have happened. HEED this man's word on that cheap foil stuff, it should be OUTLAWED it is a death trap waiting to happen ! And NEVER EVER leave a dryer on while you sleep or while your away ! It is also wise to locate a fire extinguisher close by , I now have one beside the dryer.

Great video! Thanks!

Thank you for the video!!

Very helpful. Thanks.

Thank you so much for this video!! I learned so much. I have always been OCD about keeping my dryer vents and the traps i side the dryer clear because of the fire hazards. I recently bought a new home with the dryer vent going up to the attic space and out the side like the one in this video and I have been terrified of it. 🫣😆 I had never seen one like this before. I am going to get my son to check it out thoroughly now to make sure everything is like you said it should be. I am so thankful to have found your video!

Hi this was helpful thanks for sharing

thanks, excellent video.

Best video. My vent is in the floor. Any special recommendations on how to keep lint from from blowing back into the house?

What do you use to insulate a dryer vent going directly outside from laundry room? Room is very cold. As well, how do you attach the hose to the back of the dryer and then push back against the wall, so the hose or pipe is not too long? Thanks for the update on the flexible hose, that it is not safe.

thank you very much for your video.

Good job, but in my research, most say to keep length to about 15' and that each 90 deg bend adds about 4', so you look to have well over 20', which supposedly requires a booster fan. What do you think?

You’ll have the same issue with clogging because that duct looks to be longer than 25’ which is the maximum length for dryer duct. Every elbow adds 5’ to the length and there looks to be at least 2-90 Degree turns! This will cause the lint to collect in your duct no matter what type of hose you use because at 25’ or longer, the moisture from your dryer stays inside the duct. After awhile your cloths won’t dry and your dryer will get very hot on the outside... that in itself is a fire hazard. A dryer duct this long requires a booster fan at least 15’ downstream from your dryer!

My apartment has the same aluminum flexible duct going directly to the basement. It is disgusting because this kind of duct accumulates lints easily. And because most of the duct is hidden behind the wall and it probably curls into angles it is hard to clean. I don’t understand why don’t people just use the hard straight duct. I think you should always use that one outside the room. The flexible type is only suitable for connecting a visible space from the wall to your dryer.

Thanks that helped me so much

Thank you.

Very helpful!

Gracias for the video.

I hope that whomever installed my dryer vent has the opportunity to watch your post. Nicely done.

Thank you. Very good.

Just FYI, IRC for 2012-NEW construction code M1601.4.1 requires a minimum of 3 screws equally spaced and not extending more than 1/8” at all joints and seems

That looks to be an incredible distance for the venting of a dryer. Unless you have a “phenomenal blower” on your dryer I do not see how it’s possible for the lint and moisture to travel all the way up your wall into the attic and then make a sharpe, 90 degree turn and travel additional distance of what appears to be another 15’ to 20’, if not more. Dryers should be vented to the closest outside wall. I sincerely encourage you to hire a professional who can advise you, or call your locale county Buiding Inspector’s office to inquire about what your city code requires. It is better to be safe than sorry.

i recommend the Magvent . it makes it very easy to clean. it makes it look clean behind the dryer

Nice to know that. Would pvc work with clean out?

Oh my goodness thank u so much Fr ur info! I have the slingy one in my apartment right now but will be replacing it tommrrw & I will not be using my dryer until it’s replaced! Thank u so much Fr saving our lives ur a true blessing!! 😧🙏🫶

Thank you so much!!

thanks, i have been in the remodeling business for years and never really thought about dryer venting too much. i did know that fires used to start in dryer vents so i figured i look it up. this video came #2 on youtube. i am glad i stayed tuned through the repetitive first chapter. i have a thing about being told the same thing over and over, that drives me crazy. videos have a rewind function and it should be used by those who didn't quite catch what was said the first time around. that aside, i would have built my dryer vent all wrong if i hadn't watched this video, so thanks for taking the time to record and post this video, you may have just saved my family's life or our house from fire. thanks again one thing i forgot to ask at 3:44 there is a small line connected to the vent near the dryer, what is it?

I appreciate you posting this video. It was helpful. Where can one pick up long sections of that fully rigid aluminum tube that you ran in the attic? I'm having a hard time coming up with anything relevant on Google.

All the houses down here have long vertical dryer vents. I blow mine out with my leave blower every year.

very informative

In Canada where it gets cold the duct has to be insulated to prevent it getting wet with condensation in the attic during winter.

Also do you need the aluminum tape as well as the clamps for both the connections at the dryer and the exterior vent pipe?

I'd like to see just one video that shows how you connect the duct work to the back of the dryer when it's only 8" from the wall in the back and no room on the sides.

Thank you..... 10 years later still important

You the man brotha

THANK YOUUUUUU!!!🙌🏼

Good stuff

Thanks!

Vertical runs of dryer vent is risky business. Cleaning protocols would need to be more frequent.

What would you use or recommend when you are behind the dryer it doesn’t go int the wall. It goes straight into the floor. Then through the crawl space and out the end of the house. It has that crappy slinky hose under the house and I know it’s not safe and It comes loose often.

Thank you !!!!!

Great video, but what about condensation?

What do you when you come through the header? Just squash the duct down a bit?

I need help i did the same hard pipe installation same length and everything with a dryer box but is it normal for the pipe to get really hot will it cause any damage to the drywall or anything ?

I have a dryer about 8 feet from a block glass with a vent. The room is not heated or cooled...it;s in a basement. Is there a pre-insulated metal solution I can use?

Thank you so much I see why sears said I wasn’t in compliance I had the duck that you did not recommend

Duct wrap has to be used to insulate the pipe in attic, to avoid condensation.

Good video, but I have read the maximum recommended safe exhaust pipe distance from a dryer to the exit port is 25 feet, MINUS five feet for each 90 degree bend in the travel. You do not mention this in your video. Any comment? Also, I see the run in the attic is straight pipe (not flex). Would you recommend straight pipe over flex wherever possible, as the lint tends to build up quicker in flex?

I inside wall duct is damaged at the end that comes out of the wall. Is there anything I can connect to it to reach out of the wall to connect to my vent tube that goes to the dryer?

my dryer area is cramped for space. will the metal one work?

Excellent video! But I have a question! I found two small hole in my dryer vent, can I use foil tape to repair/seal the holes?

BRAVO.

Thanks soo much I needed this

No screws (at connection points) makes sense, but I've never heard of aluminum tape, and I imagine it will cost a fortune (for my limited income, everything over $5 is a fortune) - my aluminum hose came equipped with adjustable rings that are tightened/loosened by an external screw. They have served me well so far, but, what do the pros say?

Thanks bro

I need to install a duct from the attic to the side wall of the house. Is there a video on how to do that? Currently my dryer vent is connected to the attic so all the heat is escaping into the attic

I had p-lastic & removed it & got the slinky aluminum one..I had noise in my dryer & Sears who came out several times over $125.00 & 90 days later howling again..I was told by an honest handyman to disconnect it & see if it sops, it did..but still have the problem with it going through linoleum floor down & it vents to my crawlspace...Now what?! Anybody do work in Fort Myers manufactured home= smallish crawl space, too.

Been there, done that!

How about metal claps at the joints over the aluminum tape?

It appears in the attic that you have the Crimped end of your 4 inch pipe pointing to the outlet of the dryer that is Incorrect all crimped ends must point to the outside or they will catch lint and plug up eventually

Thanks!

How long can it be before you have to put a booster fan? Thanks

Was there a mention of how long the vent hose should be between dryer and vent? Yours looks really short, but our landlord has 4-5ft of it coming from the wall

The foil ducts actually contain a bit of a plastic lining (not as much material as vinyl, but still won't hold up in a fire). It would actually be better if it were paper

Can you share the make and manufacturer of the semi rigid piping with the swivel elbows? Looking on Lowes and HD I read reviews that they don't have swivel elbows or the clamps are a POS. Yours looks well made. I'd like to be able to purchase your exact unit.

My last house had the dryer vented thru the attic. It's probably the absolute worst way to vent a dryer. The lint can not travel straight up for that distance. It all collects in the bottom elbow. Also, moisture has a hard time too, and it will collect in the bottom elbow and create water. Water plus lint equals a blocked dryer vent. I had to install a drain line in the elbow and tie it in with the washing machine drain to keep it dry. The laundry room was located in the middle of the house, it is just a horrible location for venting. If I had stayed there any longer, I would have put an inline exhaust fan in the attic to help it pull the dryer air up the wall and out of the roof. Terrible design in an otherwise cool house.

Hi where could I buy the metal one with the 2 90 degree angles

Install hard metal round ducts in the wall and attic. That’s the code

I'm renting a very old trailer that has a triangular vent both on the inside going to the outside vent and my dryer is circular.

There is no Dryer Vent in CA. What is the next best brand to purchase?

In a perfect world there would be a short duct run to the outside and as few elbows as possible and no verticle ducting.

And where does the lint go? It goes thru the duct but where doest eventually end up? Im building a home , and this kind of dryers arent popular here in midle east but i love them so im gonna take thid in consedration. Help please

WOW!!!!!!!!!!!! SHAKING MY HEAD !!!!!!!!!!

what company makes the heavy duty aluminum one?

Condensation should be horrendous in that pipe through the attic

Hey Doc; I have a customer who has a dryer vent from his Electric dryer on the 2nd floor of his home that goes into his cold attic. The metal duct then runs on an upward 45 degree angle 25ft to the other side of his home and exits the roof. This creates so much condensation and drips through his drywall. Do you think insulated duct will work?

Do you recommend an inline turbo fan to assist in ventilation for that length of venting?

I was told you never vent out the soffit because that soffit is supposed to pull outside cool air in and run up along the sheathing and out the ridge vent when you vent out the soffit you're essentially going to draw that moist hot air right back in along the sheathing and over time you'll start to see black mold where you exited that dryer vent out the soffit

I have the same System and I Use my EGo Battery 🔋 🍃 🍂 blower every 6 months to it push everything outside from my attic. New Bad ass LG 7901be Gas Dryer is been delivered tomorrow to match the LG Washer and replace my 7 year old Kenmore.

please put brand name in description and where to buy
