Extending Dryer Vent

Hello, all. I look forward to becoming a member of this community!

Just purchased a new house, and I thought this 8ft dryer vent would be long enough to reach the exit, but it's not. I'm about 2 feet short.

The vent: Amazon.com: Whirlpool 4396727RP 8-Feet Dryer Vent with Clamps: Home Improvement

What would you recommend? Should I buy another vent and tape them together with foil tape? Or, should I try some sort of elbow?

A huge thank you to the community!

Pardon me.....but what the heck is that vent line doing ten feet off the ground. I can't believe that was there when the house was built. Somehow I don't think an inspector would have passed that.
Anyway...If it was me and I had to use that vent pipe I would get 4" metal ducting. Not the flex type.....actual metal ducting. Do you know where that goes and how much longer it is ? A dryer does not have unlimited strength to move air and clogging can become an issue.

I agree with PJ. Use smooth bore metal pipe and tape the joints with metal tape, starting with an elbow at the bottom. Definitely find out how much further this pipe goes. I'm not sure if there is a such thing as a booster fan for these things or not, but you are on the edge of needing something.

If there is an outside wall near the dryer I wouldn't even try to use it.

I'll bet we are going to find this is a poured monolith basement wall, yuk. Our laundry is in the basement, but only 8', and an immediate dump to the outer wall. Have to periodically clean the bottom elbow of gravity fed crud and dust bunnies.

The vent elbows, I think, at the ceiling and goes straight outside. I'm guessing roughly 2ft from that top elbow.

This is on the ground floor, by the way. No idea why builder had it this way, but I'd like to have the best (and most cost efficient) solution possible.

Where does this exit the house? I moved my vent from what the builder installed, which was something akin to what you have. Now the rise and run are shorter and I can reach the exit on the outside of the house standing on the ground to clear the clog which builds up there every few months.

Outside, it's about 10-11 ft off the ground.

It seems like a decent ordeal to change the vent location, doesn't it?

I figured it was less work than I would have dealing with that convoluted path and trying to clean out the vent 10' above the ground. Took me an afternoon.

I might be over my head with that, not sure. The external wall is brick, and I doubt I have the equipment to make that work.

A rented core drill would do the brick easily. Even a three eighths inch plug-in drill with a quarter inch masonry bit and a cold chisel would do it. An angel grinder or circular saw would help. Remember if it is a modern house the brick is only a facade one layer thick.
