Just asking because I thought I read there should be but hubby doesn't do anything and being that this is flammable stuff we are playing with I thought I should ask.DonnaOh, we have the internal kind in a class C.Also, can we add an auxillary tank with a tube to the outside sothat we have more propane in Canada...there is a bbq grill gashook up there already. We want to add a 20 lb. tank. Do weneed a switch or something to switch from internal tank to outsidetank?

just guessing here but I would think your bbq hook up is low pressure and any external tank you add would need a regulator to drop the pressure?bumpy

No maintenance require other than normal cleaning and wiping, Look at it every once in a while for damage to the valve hoses and regulator.

When de-winterizing I use a dilute dish soap to check for leaks.

They do need to be re-certified after about 10 years of use. Other than that just keep them clean and as free of rust as possible.

Glad to see some caught it/got it right--tanks vs cylinders. Some propane vendors don't know.

Propane cylinders have a re-certification requirement 12 yrs. after date of mfg. stamped on collar
Propane tanks do not have this requirement......but it is recommended that 10 yrs. after mfg. date that the relief valve be replaced

Okay, I've got to ask. Where is this recommendation in writing that the relief valve be replaced after ten years and how many of you have replaced yours at ten years?

There is no recertification requirement for the permanently installed ASME LP tanks typically used on motorhomes in the US period, end of story. Only the portable DOT cylinders more commonly used on TT's require periodic recertification. See the previously posted cites...

Dutch I get the feeling you meant that for me.

My post was in 2 parts.. in the Motor home part I mentioned inspection and re-paint as needed, Perhaps I should have been more specific inspection by the owner.

I mentioned re-certification only under "Portable tanks" and clearly set the two sections apart.

Of course, if you meant that for someone else.. Apologies now.

When a propane tank reaches 10 years, it MUST be recertified before it can be refilled. There is a manufacturing date stamped on the bottle. When it reaches the 10 year limit, just take it to a certified propane vendor and they can usually do the inspection and recertification.

As others have stated, just make sure you take care of rust issues and you'll get a long life out of them.

This is true for the removable bottles. The built in tanks attached to the RV frame are covered by a different set of rules and are exempt from this.

It was in a Propane Council Education & Research Tech Fact Sheet....Link to download of that Tech Sheet CLICKY
Replacing the safety relief valve was a mfg. 'recommendation' not a requirement by NFPA/ASME.
One of those practical safety recommendations.
And I doubt any have been changed out unless they were problematic.
