Duct Dynasty
Wednesday, January 6th, 2021Curing my Dryer’s Asthma
I have been writing about my wonderful new eco-hostile washer, and the news has gotten even better. I got my old dryer to work correctly.
My old washer was a $1300 LG. The dryer matched it. I don’t know what it cost. I’m sure it was not cheap. It has all sorts of unnecessary programs on it.
I hated the dryer because, just like the washer, it lied. The timer would say my “normal” load (whatever that is) would be dry in 41 minutes, and it always came out damp. I had to run things through twice or use the heavy duty setting.
At some point it occurred to me that there might be a venting issue. Maybe lint had gotten past the filter and clogged things up.
The other day after I installed my washer, I realized it was time to quit behaving disgracefully and attack the dryer. I researched a little, and I learned two things.
1. Dryer ducts clog with lint even when the filters work.
2. Dryer duct clogging is one of the main reasons for house fires.
This was my first dryer duct. I should add that. I’m used to holes that lead directly to the outdoors. You can’t get much of a clog in a passage 9″ long. I had no idea dryer ducts needed maintenance.
My current duct is a 4″ PVC pipe maybe 15 feet long, with several bends in it. Not a pushover, as dryer ducts go. I read up on special tools made for the job.
They make plastic rods that attach to each other end-to-end like Bangalore torpedo segments. You put a brush on the far end, you connect the near end to a drill, and you shove the rods and brush through your duct. They will bend and go through 90° bends just fine.
When you’re done, you have a huge collection of loose lint you have to get out of your duct.
I read about this stuff, and I thought, “I have a leaf blower. Why would I pay for a tool I don’t need?”
I moved my dryer out and disconnected it from the tube leading to the duct. I shoved my electric leaf blower’s nozzle into the tube. I ran it for a while. Then I went outside and discovered I had made it snow in my yard. Lavender snow. A fair amount of lint had come out, but I knew it wasn’t enough to get the job done.
I gave up and bought a duct-cleaning tool. I ran it through the system from both ends and used the leaf blower again. I used another special drill-mounted brush to clean the PVC fitting on the external end of the duct.
When I ran the dryer, miraculously, it dried clothes in 41 minutes.
In a couple of hours, I can go through three big loads of laundry. They come out mold-free and dry. If I could remember the last time things worked this way, I would probably have to reach back to 2005.
I don’t know why I’m such a bad home maintenance engineer. A lot of things have jumped up and surprised me. People aren’t born knowing about dryer ducts.
Another project awaits. Water heaters have sacrificial zinc anodes to retard corrosion. These are long rods (sometimes jointed) that you lower into a water heater through a hole in the top. The hope is that the zinc will dissolve and your steel will not. You’re supposed to change these rods regularly. I never knew they existed until maybe 2019. I don’t know if my anodes are worth changing. Maybe my tanks are made of pure rust now. I plan to find out.
I’ve also learned that it’s important to connect hoses to water tanks and drain the sediment. I haven’t done that yet. I’ve never known another person who mentioned doing it.
I heartily suggest you check your dryer ducts. I don’t know how an electric dryer could cause a fire, but you might as well be safe and have a dryer that works. The tool is between 30 and 40 bucks at Lowe’s.
When my water heaters are fixed, maybe it will be time to replace my awful oven. It blows its own thermal fuse every time I run the clean cycle. The clean cycle is not a luxury. It’s a must. You can’t clean a baking stone any other way. Fortunately, I have a Harbor Freight hydraulic cart, so I can remove and install ovens alone.
I’m very happy with my laundry machines. They look very different, but sometimes interracial marriages work out very well. I almost hope the old washer is somewhere being punished.
