jodil Posted July 7, 2009 Report Share Posted July 7, 2009 Is it acceptable to use a copper flex line at hte gas supply for the water heater? Since it has no drip leg how does this affect the unit? Thank you Quote Link to comment Share on other sites More sharing options...
Chad Fabry Posted July 7, 2009 Report Share Posted July 7, 2009 Schedule K Copper is used worldwide as piping for natural gas. Call the local gas supplier and ask them if they approve the use of copper. I used it in my house. It beats having couplings in the wall Quote Link to comment Share on other sites More sharing options...

Since it has no drip leg how does this affect the unit? Thank you If the copper flex is listed for gas (not the stuff listed for water) and if your local authority allows copper gas lines, there's nothing wrong with it. There's no reason why you can't use a sediment trap in conjunction with flex gas pipe. They're not mutually exclusive. - Jim Katen, Oregon Quote Link to comment Share on other sites More sharing options...

Since it has no drip leg how does this affect the unit? Thank you Chad is correct, however the copper line should either have a yellow strip all ready on it denoting gas or painted yellow, my first experience with this was in 1982, this is supposed to help prevent the plumber from tapping into the gas line to supply water to the ice dispenser, or any other need for water. A lot of plumbers have moved on to the stainless steel line that have a yellow vinyl coating on them. Good luck Tim ' Quote Link to comment Share on other sites More sharing options...

There's also a flexible copper product out there that comes with a yellow plastic jacket -- very similar to CSST only flexible copper. - Jim Katen, Oregon Quote Link to comment Share on other sites More sharing options...
