Default New Gas Line Install

After having ridiculously high quotes to run 22 feet of gas line (t'ing off existing 1/2"); I've bought 25' of Pro-Flex line, and necessary fittings . . . all in right at $100.

I've run copper, PVC, and black iron before; but this flex line looks super easy and efficient.

Anyone have experience with the fittings/union to existing black iron and/or tricks to keep in mind? I've already measured and ready to install; looks like about an hour's worth of work; looking for thoughts as I peruse the YouTube "experts."

I'm assuming you're talking about SST? Be careful with that stuff, and make sure you're only using the manufacturer's fittings for that specific type of piping. You can't mix and match different manufacturer's fittings.

Not sure where you're located, but here in Massachusetts there are very strict rules about bonding/grounding and hanger spacing. Needless to say, for 22' of pipe, I personally use black iron.

Also, you say "teeing in off a 1/2" line"... that doesn't sound right. I'm guessing the "ridiculously high quotes" probably include upsizing your main to feed that new branch and other branches. You need to do a gas calculation, or you could effectively starve utilities on that line if you add a new branch without upsizing according to the rated charts.

Good luck, be safe.

Yes, CSST. The nut connecting from the flex line to the black pipe "T" will be grounded via bond to the bus bar with 6 gauge. No, the quotes did NOT include a new run. Yes, Pro-Flex fittings to go on Pro-Flex corrugated. I'm not at capacity - $1,250 for a run from an existing 90* elbow (replace with "T") and go up 3 feet to new appliance. It's silly. Not rocket science. Besides . . . if I do it myself I know it will be solid and done correctly. The manufacturer has training posted on-line; seems pretty idiot-proof; just looking to see if others have additional insights.

I had a similar situation and got a couple quotes from 8-1100. I finally had an independent plumber come out and do it for 275. It's not hard; and there's got to be a plumber out there willing to do it for less.

I ran iron pipe all the way across my cellar to feed a new gas fireplace .
Pretty simple. I had a plumber come in and just tighten the fittings.
I wanted an inspector to sign off on it.
I'm sitting by the fire as we speak.i was told to stay away from the flex stuff and run black pipe instead .

When I did my oil to gas conversion plus new gas range and dryer my plumber used all iron pipe. Main oil to gas conversion was pricey but the runs to my appliances were fairly short and he charged me about $300 for each installed at different times.

I'd pay $300 for the convenience. But a grand for an hour of work is BS. These guys have gotten fat and happy telling granny to raid the piggy bank because she wants hot water. They come across people who don't mind getting their hands dirty, and really don't mind losing the job . . . lots more little old ladies with kids who live 5 States away.

I just got a quote to swap out a 30 gallon hot water heater. $1300. Come on.

Just by coincidence, I've been looking into running a gas line and have been considering CSST as an option. From what I've read, you need to make sure it's properly grounded. Also, I've been told that you need to be certified to install the stuff. Personally, I'm partial to black iron pipe as I've run enough of that to feel comfortable with what I'm doing. But I might just hire someone if I go the CSST route.

Done plenty of those. Easy job. If you want to go the "stupid simple" route: shark bite connections. Just TOOO easy. No more than $300 for tank and all fittings.

You should become a licensed plumber.

I installed the one that needs replacement 12 years ago. My tenant was trying to be helpful and brought someone in. He claimed he was giving her a deal!

All my tools are at another property about 100 miles away, so I am thinking about going the shark bite route.

I wanted to run gas to my house, had a price of 120k, then they called back to say there was a mistake, the price was not correct, wow, thank god

The right price is $500k, consider yourself lucky.

Exactly my point.

No big deal... we'll just rip off a bunch of old ladies, cuz that's what we plumbers do...

Gas line go with black pipe. Little bit of pipe dope and a pipe wrench and your done.

As far as the water heater, don't waste your times with shark bites. Save yourself the hassle of the leak that you are going to have eventually and buy a 25 dollar torch and sweat the fittings.

I just ran about 50 feet of black pipe to a new gas cooktop I installed. It was pretty easy. Use pipe dope on the threads instead of tape, They don't need to be cranked together as hard as one may think. Check the joints with a 50/50 mix of dish soap and water. Also make sure to paint anything on the outside of the house as the black pipe will rust up in no time. Also don't forget to put a trap in.

Do you have any first hand knowledge of SharkBite leaks? I have done thousands of soldered or brazed fittings, never a SharkBite. However, I've heard good reviews of SharkBite's and recommended it's use to someone that was capping off a 1/2" H2O pipe below the floor it was coming up through before being cut off.

I've used everything but that pro-flex, just like the clean look of rigid pipe.

Anyway, we all know how easy it is and glad to see you've decided to do it on your own as there's a high likelihood you'll do a much better and cleaner job.

Good luck!

Good advice. The main reason to use pipe dope is because you're not supposed to use tape. Even with dope, try not to get any on the first thread as you don't want any to get on the inside of the pipe. Be sure the dope is for gas and some are better than others (I can't think of the names).

I have a nice Rigid Threading machine with maybe 15 dies (2" max) that I'd rent or sell if anyone wants to make a trip.
