Need to know if can use flexiable pipes to connect a hot water heater.
Can I use a Flexible pipe on a Natural Gas line?
Can I use a flexible pipe on the hot and cold water lines?
If so, Please recommend brand or link to one I can pick up a plumbing store.


Please note I live in NJ it should be code. I don't want any short cuts.

Thanks.

We will have to get input from a NJ plumber because it varies. In California, flexible connectors on the gas and water lines are MANDATORY. In some states, such are ILLEGAL. Many states are in between.

Here in NC you can use flexs on both the gas and water, but neither is required. I opt to hard pipe both.

it looks unprofessional to use flexible connections and can be more dangerous if kids start pulling on them...i understand the use of flexible connections in earth quake zones, but in NJ i cant imagine it to be a typical install....id hard pipe it all

Have YOU ever tried "pulling on" a flexible copper water supply? IF you could even move it, after it was connected, you would be better than most people. And is this kid wuld have to be some kind of 600# gorilla if he could pull a stainless steel gas flex apart.

Flex is the only way they're connected here in shaky-town. Once every other blue moon I come across a flex that's loosened up, and I snug it. No other problems to report with them. Hard pipe would look unprofessional here.

BTW, I only use the corrugated flexes as the braided ones aren't full-port.

Some of the corregated flex water supplies are not 3/4 but some of the more expensive flex supplies that can be bent numerous times are. Water heater mfg do not allow flex for the TPR discharge because it is less than the 3/4 and has a slight restriction.But I see flex all the time being used for TPR discharge
