Very efficient process. That elbow with the hole drilled through it was particularly creative. Great work, I will definitely incorporate these methods in my application.

Man, we want to see the lint!!!

I recommend from the outside. You can visually tell when it's clean because it will go from lint to dust to air. When just air while you brush it's clean. You will do more passes from the inside to get it clean like 6-10 vs. 2-3 from the outside. Confirmed with sewer camera. What's more is You don't have to retape and do flex lines and move the dryer because it is already done. You will save a lot of time and effort going from the outside. I only go from the inside if the roof is hard or unaccessable to get to.

What was the speed before cleaning?

Alternatively, if you clean it from the inside, you can manually guide the brush all the way through and clean it as you retract it back.

Been doing it like that for years with a little grate I got years ago from a lint eater kit. I use air mostly but it sure is nice to be able to just let it fly through full send without having to listen or measure to get 100% to the end

How do you know when to do it inside or outside

That "transition hose" should be thrown in the garbage. It is the #1 reason for build up in the pipe. It should be hard pipe the entire way with a 90 deg elbow at the bottom. If cut properly it can be pushed on as the dryer is moved back against the wall. Flex pipe, yes even foil flex is the main reason for dryer vent fires.

HELLYEAH keep thinking like that

Why did you choose to clean the vent from the outside instead of cleaning from the inside?

Why don’t the yanks just vent a drier straight through the wall behind it?

What is that flow meter device?

What is the Rod make and model?

Awesome man, where did you get the rods from? I like the set up.

Never use foil flexible venting. Fire hazard. Hard on the dryer. See tag on back of dryer.

2k cfm ? From a dryer?

That flex dryer vent hose is against code. The home inspector will mark it..

Many comments on the flex hose, did you replace it with a metal hose? 😊

It didn't show any of the lint coming out

@VentVision rod kit, by far the VERY best investment I have made for my vent cleaning business

Shout out the 302 !

Where's the lint

thinking same thing

Use a reverse spinning skipper ball

How do you repair the hole you drill

ooo cool

I’m so glad I have a heat pump dryer that doesn’t need venting like this. They are extremely efficient and better for your clothes.

That's a long tube.

Ridiculous vent. Are they running it to the moon?

replace that garbage flex hose.

NEVER use a flex hose connected to the dryer. It’s a fire hazard.

Vacuum on lower side, run brush from other end

Event is terribly too long the reading on the machine that he uses to check the airflow the drive is not designed to blow through 20 ft of pipe
