flexible LP line ????

Another adventure in refurbishing my Argosy

after testing the waterlines i found out that the system is leaking like a, well you know what.

leakes in the water lines will be easy to fix for me.

The water heater is corroded through, i found out about it after taking the heater out and inspecting the tank, pinholes everywhere

so, new heater is ordered -Atwood G6A-7-.

Here is my question
i had to cut off the gas supply line from the old heater since it would mot move and damaged it a bit
so i will need to replace the line from the nearest connection which is just about 12-15 inches from the heater.
could i replace this with a flexible hose, if so where would i find one that is approved?

or do i have to replace it with copper tubing and get a flaring tool and benders?

i have included a picture of the area in question

I see no reason why you couldn`t use a flexible line,just make sure you sleeve it where it goes thru the belly pan and floor.You should be able to find a flex at a plumbing supply house,or maybe Home Depot. Dave

I recently replaced my old Bowen water heater with an Atwood heater. The entrance to the new Atwood heater for the Propane supply was in a different location than for the old heater, making it necessary to drill a new hole in the floor and provide a new propane hose. I looked everywhere locally for a flexible Propane hose with the proper connections or that could be adapted.....but no luck. I even paid a visit to the local wholesale house that is used by gas and propane installers.....but no luck. Finally, I just used soft copper tubing and made flange connections on both ends. I had access to a flange tool and a pipe cutter....but no bender. I just did the bending by hand. Not as neat as I wanted, but it works.

After it was all done, I found what I needed on the Internet at this site.

Many RV parts outfits carry flex rubber hose in various lengths used to connect your propane regulator to the main supply line to the trailer. Most will have any number of adaptors for the ends.

I would use that type of hose as it will withstand vibration as well as weather if part of it is outside the coach.

As Jim says...
Vibration makes me want flex for all lines

Does anyone know of a place to get flexible (rubber) hose for propane lines in a 30 foot length?

We have a local LP station that we get our tanks filled at that will make up any length of hose you want. You may want to check around to see if there is one by you too.

We used a 3/8 x 36' flex line from Lowe's -the yellow plastic coated stainless type. Painted the part on the outside silver and used rubber grommets where it passed through the belly and the tank housing. There was enough flex that we didn't have to drill a new hole in the floor. The excess I just curled up inside the tank housing.

I am surprised that no one has mentioned anything like a CODE. Rubber hose carrying gas inside is not a good idea. If it was don't you think the expense minded "bean counters" that control manufacturing would have adopted the use.

The yellow colored gas piping is very easy to work with and flaring is easy so do it right.

that makes sense

I just connected all appliance in a restaurant,they all came with rubber flex connectors ,and quick disconnects.They did conform to code.

This is what Gary was most likely talking about. You have to use the fittings for the product to be safe.

Had all our lpg lines made at House of Hose.It makes all kinds of hoses hydraulic, fire and any kind you want. They were made out of rubber. This is a local Las Vegas shop. but there might be something similar in your area.
