Washington Township - New Jersey
House was built in 2001
Flex gas line was used in basement from the hot water heater up to the furnace on the 2nd floor - was this built to code???
We are selling house and need to know asap - THANKS FOR ANY HELP!
What exactly do you mean by “flexible gas line?” Is it CSST (corrugated stainless steel) or a pre-manufactured appliance connector? Any pictures?
What size is the gas line at the water heater? How was the gas line split to the appliances?
Thanks so much for the response Mr. Pope - yes, it is CSST - it looks to be about an 1.5"—I will post a pic tomorrow (Wed)…it appears to be the same CSST as installed throughout the house’s other furnace, but, the yellow sleeve was frayed from the original installation - we are being told it may not be code compliant today but we know the rest of the houses in our area were like ours and have this as original construction in 2001 (we are original owners)…we are looking to see if we are "grandfathered’ into the code from 2001 vs today’s code and simply just want to repair the frayed portion vs replacing the entire line with different material before selling the house
Follow Larry’s link and read about it.
Make sure it is bonded.
The pipe needs to be bonded properly, per the manufacture. I have attached a link from one of the manufacture instructions for this pipe.
CSST is perfectly acceptable by most model codes. If it was acceptable at the time of construction, it’s still acceptable unless your local jurisdiction has prohibited its use. A call to the Building & Safety Department will clear it up quickly.
Codes are not retroactive (that’s the concept behind “grandfathering”).
As Bob eluded to, there are additional bonding requirements when CSST is installed. If you are in a high lightning zone (LDZ - Lightning Density Zone) you may need additional bonding of the gas lines to the residence grounding electrode.
Thanks to everyone for all the info - it was very helpful!!!
