what is a transition fitting?

[Another-Plumber]

gas company came out and tagged a water heater for a customer of mine, the note says needs transition fitting, wtf is that? i called the gas company and they dont know, they will need to send the tech back out in a few days and for me to hang out during the 4 hour window... anyone know what that can be...

I believe they are referring to a union, which will allow the W/H to be removed and replaced.

cant be, the water heater is in a garage, copper water flexs, gas flex, t&p piped outside, yet, yet they tag it, i have called every plumber i know, googled it, and no one knows shait...

Sounds like they may require a dielectric union between the copper and the heater.

wouldnt it be ok going from black steel pipe to a brass shutoff then flex?

You need a union between the shutoff and the flex (just after the shutoff).If no union , that should be the problem - If you have a union there,codes has changed.

Are you talking about the gas line? If so how would you connect the heater without one?

always use a union

 

[phishfood]

The flare end of a gas flex line serves as a union. I have never been required to use a union, per se, when hooking up a fixture with a gas flex.

Sorry IFIXH0 I misunderstood your post. I thought you were saying NOT to use a union.

A transition fitting is a double fitting that allows u to connect to something else. For instance a mission coupling, copper to plastic.

Have you looked at the venting ? I am thinking this is where your problem is, its on the tip of my mind right now but im currentlly pretty ill. could be a vent connector, or if the vent is run single wall and becomes common ( maybe with a furnace connection or to a double wall vent )

 

[Another-Plumber]

1st of all putting a UNION after the shut off is plain stupid, show me a picture of a "flared gas shut off-union-gas flex".... CANT BE DONE, unless your some kind of hack

 

[LiQuId]

[Another-Plumber]

liq, i understand it may be the vent, however it goes for 3 inch single wall to double wall... so what gives
