I'm looking for comments and suggestions on whether it's safe and
practical to run 20 feet of 4" metal exhaust duct horizontally from my
relocated clothes dryer to tie into an existing 4" dryer duct which
runs about 20 feet vertically. The existing vertical duct is
uninsulated and is inside an always-warm house without air
conditioning.

Thanks in advance for your replies.

I would check with the manufacturer, they have specifics as to how long and
how many bends are acceptable. You can always get a dryer duct booster fan

In addition to checking with the manufacturer for duct length,
consider lint accumulation and clean outs.

The problem with extra-long runs is the fan inside the dryer may not be able
to push the air that far, especially after a year or so & the tube gains
some wind resistance in the form of lint that catches on things on the
inside of the vent (this is why you don't screw dryer vent tube sections
together). Wind resistance is also one reason why the flexible vinyl hose
is not recommended (the other being it can catch on fire).

Check with the mfgr, see what they say about maximum vent length.

longer length means less efficent drying more energy use, adds regular
maintence cleaning out line, and isnt a good idea.

would a NEW vent be shorter, if so install a new one.

Too long of a run! Buy yourself a Fantech dryer booster fan and install
it near the END of the line just before it goes out of the house.
Everyone should install one if the duct is over 12' long, it will help
dry your clothes better, and cut drying times.

40' is way too long. While some posters say to check with manufacturer
recomendations, these always are very liberal numbers, and you would do
yourself a favor to cut the number in half. A booster might solve
some, but not all of your problem.

It is against most codes to "tie into" an existing dryer vent duct.
Why can't you run this independently?

It might have been better for me to use the word "connect" instead of
"tie-in". The entire duct would serve only one dryer.

There's some stuff at the bottom of her page about it.

There's also a link to an online casino. Not something I'd want to be
associated with...

Thank you for telling me about the online casino link. It was a

No sweat Alisa. Considering this is a legit business page, it's bad ties.
Obviously you agree.
