I bought a tri-fuel generator and I need a 1/2" gas line added at my gas main as it comes into the house. The gas main is close to he electrical panel so it makes since to put the generate close to both sources. The other option is the run either 60 feet of electrical cord to the patio area where I have a grill hooked up to a 1/2" line already there.

How much do you think a plumber would charge to add a 1/2 in with valve and quick connect?

The cost of pipe and Teflon. You have the fitting already. Shut the gas off, add a pup joint with a gas valve, thread pipe, add in the other pipe, add another gas valve. Done. Probably an hours worth of work which includes going to Home Depot for the pipe

damn man its not rocket science, just add the pipe fittings and your done, home depot has everything you need to do it yourself

unscrew pipe under the tee, ad another tee and a short nipple and a shut off valve and then add the fittings you need to run it anywhere you want it, then strap the pipe to the brick with clamps and masonry anchor screws

i bet you spend less the $100 on the galvanized pipe and fittings and its just an hours work to do it

the pipe at the bottom is there to collect any water that builds up in the gas line so thats why its there like that

Pretty sure you need black iron for gas line, not galvanized. Probably 30 bucks worth of parts. There's a lockout valve to turn off the gas at the bottom of the meter. Some pipe dope and pipe wrenches to add the fittings you need. I'd probably do 3/4" as much as possible.

So just turn the gas off, unscrew the cap that is at the bottom of the tee that goes into the house, add another tee to tap the line off (with a shutoff valve and 1/2" quick connect) and create another dead end to catch the moisture. Its that easy.

See setup I purchased earlier today in the post below.

Not sure if this is meant to be a 350 joke from the OT, but it might be pretty accurate, but I would guess on the high end. A licensed plumber is going to be $100 to $150 per hour, but they might charge a 2 hour minimum, and as others have said, the parts should be not much more than $50. And the plumber would also relight any pilot lights you might have in the house (water heaters, gas range,etc) after he’s finished.

I have gas water heater and a gas range but I think they have "electric start" and not a traditional pilot light. Is this possible as I have never had to relight a pilot light in over 10 years.

no not outside, anything under ground or gets exposed to weather is galvanized

they only use black iron pipe inside where it doesnt get wet because it starts rusting immediately after installing it

its about cost savings to use the cheaper faster rusting black iron

My outside piping is black iron painted grey....

The picture he posted is painted grey (therefore not galvanized).

OP what size generator are you running? You need to confirm that your gas supply and current meter will supply what you need. Its possible you need to upgrade meters.

and oi installed residential gas lines to new houses for 25 years

you can find many contractors who use cheap materials and paint them instead of the proper pipe that should be used

black iron and galvanized are the exact same pipe, one is galvanized to prevent rust and one is just painted and starts rusting instantly

Yep, the black iron uncoated pipe outside(rusted to hell but still holding) and under ground(completely disintegrated) needs to be replaced after ~15 years at my house.

I went to get this set up at lunch. Does it look correct? (just insert it to the existing setup above the water pipe that terminates before it enters the house)

How has no one suggested hooking it up on the other side of the meter?

Seriously though, you mention the connection for your grill on the patio. You could have gone with a flexible natural gas hose with quick connects to get you most of the way to the electrical box. But it looks like you are set up with parts and comfortable enough to DIY. Good luck.

The grill is 65 feet away so if I set the genset up close to the both the electrical panel and gas main I can avoid the cost of a long run of gas and /or 10/4 electrical cord AND the most importantly the generator is on the side of my house where my AC units are and the noise will be reduced considerably. The grill is on my patio and the noise would be too much and this set up eliminates that issue.

The Remains of time gone by as none of that is active. Before I owned the house I have old school hard wired phones, an alarm system, former Cox coaxial cable & internet, Local utility cable and fiber. The only service I have know is ATT Fiber and its on another wall. I guess I should just cut all that away!

Checking online, there's about an 80/20 split on using black iron pipe versus galvanized. The main issue with galvanized pipe is the zinc flaking off internally and potentially plugging a downstream orifice. Proceed at your own risk with these fittings.

I would check the tag on the valve and make sure it's rated for gas service. This *appears* to be a generic valve rated for water service, not gas.

There is a pipe thread compound made for gas service - use this instead of Teflon tape, as shredded tape pieces can also plug downstream orifices.
