Is This a Gas Line in My Laundry Room?

Purchased a new place and below is a photo of my laundry room. I see a wire coming from the floor. Is this a gas line? If so, I'll have the option of going electric or gas dryer. What's the preference these days?

That may be a 240v dryer receptacle installed originally in the house.
The gas line look to be added in later.

A gas dryer is more expensive but dries much more economically with gas as opposed to electric.
I would always choose gas over electric.

FYI.... if you decide not to use that gas line... the line MUST be blanked off.
A gas valve with an attached line cannot be left like that.

Sure looks like it. Gas is pricy right now. And gas appliances must be vented. No one has ever gotten carbon monoxide poisoning from an electric dryer. 😉

Thanks!

Looking back at the photo, appears I will have to go with gas as the outlet is standard and not 220v.

I believe that flexible duct is no good for a gas dryer! Also it is 240V not 220V and technically a 240V is a standard outlet as long as it is a NEMA pattern which would be either a 10-30R or a 14-30R depending on the age of the building/house

Thanks for educating me CircuitBreaker

I'll have to take a look when I have access to this property, but looks like the white area in the middle could be covering an existing 240V outlet?

I blew up the picture and that is what I see to be a covered up or painted 240V dryer receptacle.

Methane is an indoor and outdoor pollutant. I would not use it in a laundry room unless there's an exhaust fan or openable window in the room. We are starting to see municipalities ban methane.

Also, that gas line flex pipe MUST be replaced with a new corrugated (yellow) line. Do not use the existing one and go with a hard pipe vent, not the flex vents.

...banning natural gas in new construction... is not exactly banning natural gas.

Truly appreciate all the responses!

Norm201 based on your response, can you confirm if these items would work with a gas dryer?

Hard vent

Yellow line

Since my vent area is in the floor, does anyone have recommendations? All the hard vents I see are meant to used with wall vent.

I'm thinking two adjustable elbows and straight hard vent pipe?

Never saw dryer vent going down through a floor. Does that mean it exhaust down into crawl space outside? If so, I would want to be careful where that moist air is being exposed to. For instance, if the underside is particle board that moist air from the dryer is not good.

Do you know for sure that the vent goes to the outside? A vent emptying into a crawl space, basement or occupied space is not allowed and will cause major moisture problems. Even a vent under an exterior deck can rot the structure.

I will verify during the week if it vents to the outside or not.

As well as the moisture problems if you use a gas dryer as well this is also very important as the vent also exhausts the combustion gases which contain CO and you don't want that venting under the house as it will make its way into the living space

My suggestion is to vent the dryer up from the bottom of dryer through the wall.

Verified: vent does vent to the outside and 240v receptacle is available as an option but I think I'll go with gas.

Question: the vent doesn't look like it has much lip area to work with. Is this normal or will this be an issue?

That fitting has four parts. The top/male fitting (red arrow) is broken off.


You can replace that one an add two more to go directly into back of dryer.
Hard to illustrate exactly but those fittings are completely adjustable.

What about the answers to post of #14 and #15? Even if it vents to the outside, where does vent to? To the underside of crawl space or out to the side?

Thanks PJmax , I'll make sure to get proper fittings for both ends Norm201 it vents down through the crawl space and exits to the outside. I'm thinking I read your question correctly.

Norm201 PJmax I plan on buying the following. Wanted to make sure I'm not missing anything:

- (2x) 90 deg elbow
- Round Metal Duct Pipe
- (2x) clamp

The fittings and that duct don't require clamps.
Use metal foil tape on all connections except for the one at the back of the dryer.

One example of foil tape. There are many choices.

​​​​​Glad I asked, really appreciate it PJmax

Also, how would I trim the metal duct pipe? Is it thin enough to use razor blade or is some sort of saw required?
