I'm not a plumber so bare with me here.

My dryer has never seemed to get as hot as I think it should. It's a kenmore He4 elite. Would switching to a 3/4 flex gas line make a difference it's a 1/2" now.

Anyone that don't mind answering this, I would appreciate, thanks

What else is on the line?
Are you asking what is down stream from it? I believe my water heater is connected with a tee in the wall. Then from there I imagine it goes to the heater. The kitchen is before it.

I'm asking if a 1/2" flex coming off the shutoff valve should be 3/4"?

Yes it's under sized. 1/2" is only for 1 hookup. I'm pretty sure you should 1" at least for the kitchen and dryer, then reduce to 3/4 for the furnace then 1/2 to the water heater.

The 1/2" goes to a valve then what does it hook to? 3/4?
I will go look, I also think a ridgid vent might help. Instead of a flex. Could allow better airflow.

Ok, it's a 1/2" gas pipe, with what looks to be a 3/8" flex coming off the shutoff. I think I was wrong about the 1/2" flex

Your exhaust vent is probably clogged or kinked.

You can run a factory of a foot of half inch, but you couldn't run a candle 500 feet away.

I checked my vent it's clear, however it's about 6' of flex vent. Probably too much for flex?

Sorry, but I don't understand the second half of your post.

that's the number one cause of house fires. But I'd spend the long weekend pulling it out and fixing it. It pull out the 1/2 and at least put 3/4
It definitely won't hurt. I will run a Ridgid vent as well. Maybe I will take the dryer exhaust a part and clean it too.

About 25 or 30 feet

I haven't done this in a while, so some one can correct me if I'm wrong, but at 30' you are putting out about 70 cfh just the dryer needs about 30cfh. 1 cubic foot is about 1000 btu. So I would say it's under sized that the dryer needs almost half of what you're getting

So if my water heater is going it is even worse? The good news with that is I can easily run it up in the rafters of my garage, the dryer is in the garage.

Yes, good thing you don't need your furnace :laughing: I found a calculator you can use http://www.engineeringtoolbox.com/natural-gas-pipe-calculator-d_1042.html so add up all the btu you need and the total length of pipe, plug in the numbers and change the pipe size until the your cfh is equal to 1000 btu (1 cfh = 1000 btu)

Thanks for the info Jesse, and your right we haven't used the furnace hardly at all this winter. It was 80 today. It will give me something to work on, my work is stalled right now due to the holidays. I need something to keep me busy.

Nah that's perfectally acceptable, although hard piping is preferred.

Sorry, but I don't understand the second half of your post.
Gas pipe is hugely distance dependent. You can have a large machine run off a short piece of pipe but you can't run a damn thing off a long one.

that's the number one cause of house fires. But I'd spend the long weekend pulling it out and fixing it. I'd pull out the 1/2 and at least put 3/4. About how long is it from the gas meter to the dryer
Don't replace gas pipe without doing a little more investigating first.

Is the dryer burner on the entire time? What does the flame look like? How hot is it getting? Can the dryer get enough make-up air for good airflow?

trace back the 1/2" to the next appliance....is more than 1 appliance on that same 1/2"line? if it enlarges to 3/4 or 1" then your fine as is.....if they have multiple appliances on the same 1/2" line then there's most likely a problem, but unless both appliances are running at the same time it should still work correctly as is
