A "G Coupling" installed in gas line?


I'm with majakdragon on this. Not too sure exactly what it is, but it does look like a compression type of fitting and not a threaded fitting. If that's the case then yes, it needs to go.

What do you think should be a fair cost for this job?. I hate to get ripped off.

I have never been under nobody's house but I was not too impressed with the plumbing under the house. Although the plumbing has been updated with cooper there is lines going in different directions, specially by the area where the two bathrooms are located.

I just got a $380 estimate to replace this fitting this saturday. I thought this was expensive. This is only to replace the old fitting with a new "gas rated" fitting and nothing else. What do you think?. Is he trying to rip me off?

This is a DIY site, and therefore we strongly discourage "what is a reasonable price for this work" questions. Get more than one estimate if you are skeptical.

i am in the business of supplying fittings, and threaded pipes.
with the install, this is a regular price.
i would say anywhere from $340 to $400 labor and materials.

Allow me to repeat myself. This sort of advice is not in keeping with a DIY site, and is therefore STRONGLY DISCOURAGED.

IF that is a compression fitting then absolutely it needs to go. In addition, you have a bushing in the threaded portion of that tee which around here anyway is a big no-no. If needing to decrease the size a reducing coupling must be used on gas piping. If the piping isnt threaded (and it looks like it isnt) then the piping itself will have to come out and be threaded. Getting everything back together with threaded joints can be a BIG pain in the dexterior! Many times it isnt just two pieces of pipe that have to be disassembled. Many times you have to take ALOT more of it apart than people realize because how are you going to screw that fitting on? Think about it....while you're tightening it onto one piece of pipe you're loosening it from the other pipe. It aint always as easy as people think.

As far as price goes, I agree with thekctermite. Trying to tell you what is fair and reasonable in this format is a disservice to you AND to the plumber who gave you the estimate. Get a couple more estimates and go with what you're comfortable with. There are so many variables that dictate price in different areas of the country that what may cost a dollar where you live might cost five dollars where I live. I know that I'm not the least expensive in my market, but I dont want to be. Of course I dont want to be on the other end of the spectrum and price myself out of jobs. You'll find that most folks in any trade want to be competitive and DO NOT want to rip anyone off. Believe me, word of mouth can work for you, but the road goes both ways. Rip off enough people and you can kiss any new business goodbye.

A "G Coupling" installed in gas line?


The more I think about this, the more I think that this is something I can do my self. All that needs to be done is to remove tap line for gas heater, cut this fitting, rethread the pipes, install new threaded fitting, install back the gas heating line, and whalla!!. Obviously this is a gas line and I would need to shut off the main gas valve... is there any safety precautions to be taken into account?. What type of fitting is recommended for this job?

Don't forget to make sure that whatever sealant you use is rated for gas. You may already know this but I like to err on the side of caution.

Not knowing what's on the other ends of the pipes. You may need a 3/4 union,, A 3/4 3/4 x 1/2'' T A 1/2 '' nipple & a 1/2'' 90 deg ell.. Depends on how you make it up if you will need a 1/2'' union. Soap test all the fittings
