Quality new dual propane regulator?

My regulator has failed before going through the first pair of tanks.

Rather then spend the $$ for fuel to get to the dealer for inspection and warranty replacement I'd rather just get a better one that will last longer.

Are there any high quality regulators set up for a typical dual tank arrangement?

Are there any that can be serviced - with readily available parts?


In my case, I assume the diaphragm is bad since propane is pouring out of the diaphragm cover when the propane is turned on and all the loads are off.

I'm in the process of heating up the regulator in case ice somehow managed to form and is keeping something open. Given that the outside temp is 37 degrees and I've been heating the regulator with 2 250 watt lights for an hour, I don't think the "melt" idea is going to pan out....
  • Sure sounds like a ruptured diaphragm. Do you have time to exchange it with the dealer by mail or fedex? I think Rego makes a better one. I'm certified to do so but I haven't seen much for repair parts since the 70s. Craig
  • I have had several of the Marshall Brass ones fail. And one of another brand. Don't remember what it was. I am now on my third type, and I also now carry a spare. This is over 20+ years. They seem to fail at random. Usually when I am a long ways from a parts store.

    I asked about a better one at a couple of RV parts stores and was met with blank stares.
  • The Marshall Brass regulator is better then the Italian made on.
    Look for one of the covers to go over the lower portion of the regulator. Make sure the vent is facing down.
