Anyone Make a 2-Tank Regulator that is Not Auto-Changeover?

I get an occasional propane smell from my 16-year-old Marshall two-tank, two-stage auto-changeover regulator, so I think it's llived its best years. It seems that all the regulators available as direct replacement have about a 20% chance of failure, either right out of the box or in the first year, based on Amazon and other vendor reviews. This is not encouraging when the tanks are a thin wall away from my head when I'm sleeping.

I never use the auto-changeover feature anyway as I don't trust both tanks being left open at once, and running the risk that I run completely out of propane without realizing the regulator has switched over. Does anyone make a good, reliable RV regulator that can be switched over manually but lacks the auto feature? Alternately, can someone point me to an auto regulator that is at least, say, 95% reliable?

  • You just buy a two stage regular and connect a T-valve to the output. I think that's what Dutchman said also. I did this long ago with my travel trailer for some reason that I no longer remember. Later on I bought an auto changeover one and it was still working fine when I sold the trailer 10 years later. No reason to believe that the T-valve won't fail and leak also but it is simpler than the auto ones are.

    Have them make you a dual hose set up with a 2 stage regulator (250# inlet/11"WC outlet)
    Reg should be rated for 160,000 btu minimum with Light Green ACME Nut (200,000 btu flow rating)

    Bob213, you are right, the current one has served me well. But it seems any of them, including Cavagna, Fairview, Marshall, and especially Camco, have their share of failures. Perhaps it is not as bad as it seems, since people are more likely to complain about a bad experience than they are to share a positive experience in the reviews.


    Guaranteed everyone with a failure screams it to the heavens while maybe one in 10,000 pipes up in praise of . . . nothing happened, it worked as expected.

    I've had one on my only RV, and a couple on my house and workshop. I paid no attention to brands, and they've all worked fine for years. Don't sweat it. And I always use them in auto mode, with both tanks turned on. If you pay no attention to the thing, of course you will one day run completely out of gas. Give it a glance once in a while already, and you will never have a problem.

    At the same time, the mathematics of statistics predicts that regardless of the finest materials, most careful and skilled craftsmanship, tight QC, and conservative design, somewhere out there is a unit that will fail prematurely in service.

    Talked to a guy a while back worried his 60,000 mile old luxury car was a lemon because the alternator BRACKET broke. Naw, man, those things suffer zero wear, and if they are strong enough to survive the first starting of the engine, they will last 500,000 miles and beyond. You just won the lottery by finding THE ONE math predicts will break anyway. Pop over to the nearest junk yard and give the man $5 for one off a wreck. You already found the bad one, the junkyard one will last forever.

  • 16 years from the Marshall seems like it served you well. They are still highly rated. Cavagna is top rated as well. Doesn't seem to be a true manual one that I can find. I had this Rego bookmarked so I'm not sure if it is still available but it says for stationary or portable.

  • DutchmenSport, that's interesting, thank you! I'll read up on it.

    BFL13, you made no answer to my question, just suggested I change the way I do things. I've been doing it my way for well over 30 years now and never run into those situations you describe, "Not a problem!" for me either. It's obvious we both have different approaches, but what we do obviously works for us. Thank you for your advice, just the same, I do see merit in your comments.

    The question remains - can anyone point me to a highly reliable two-tank valve of either type, in addition to the assembly DutchmenSport suggests? Someone here once recommended the Rego line as dependable American-made regulators, but the local Rego dealer tells me that Rego told him (upon trying to track down my part number) that they no longer make a regulator suitable for RV use. So the search continues...

    Thanks, folks!
  • Have had two different brands over the years and both worked just fine. If you don't leave both tanks open, you can get the first one to run out at 3am and freeze to death from no furnace. Of course it will be raining that night and you have to go out in your PJs to switch over.

    You can't run out from the second tank if you do your regular "rounds" of your rig in the morning to see if the regulator has turned red yet. Of course you do not turn the switch over to the second tank and make it go green until you remove the first tank to go get it refilled.

    Not a problem!
  • How about something like this. Looks like it's a single regulator with a T-valve and hoses going to each tank. This is something you could do yourself, and have 100% control over which tank is on. And its definitely not "automatic switchover"
