Propane regulator placement

[93Sovereign]

Hi,
I’d like to replace my well used regulator/pigtails with a Cavagna two tank change over, 12 inch pigtails and a new 3/8 LP hose. You will notice in the attached photos that my current regulator is placed near the bottom of the tanks. My thinking is to place a new regulator on a hanging bracket higher and close to the tank valves. My question - are there any considerations that should make me think twice about the location change? To my knowledge the current regulator postion is the only placement since the trailer rolled off the production line.

Thanks in advance for any feedback.

Not sure why no one responded. My preferred regulator is the Marshall Excelsior MEGR253, however the Cavagna is a decent regulator. Your idea to mount up top is pretty much how virtually all regulators mount. You put the crossbar across the tanks, drop the regulator bracket over the threaded rod, then install the wing nut.

If the current placement has worked all this time, then why change it?

Be sure to get a two-stage regulator. I went to a local propane supply/repair place and they had a selection of higher quality regulators than box stores carry, and they were able to make the new pigtails on site in just a few minutes.

Hi Charles and Richard,
Thank you for the reply. It appears I have options. I asked about elevating the regulator as I find my current pigtails to be long with two sizeable bends and the pigtails rub against the propane cover. They are about 3 feet. That said fortunately they do not leak.

Charles, thanks for Marshall regulator recommendation. I will look into the model. I only know the Cavanagh based on surfing Vintage Trailer Supply. So I am open to alternatives that others recommend.

The Cavagna Kosan regulator is designed in Italy and made in their own factory in China. It is probably one of the best of the China made regulators, somewhat unique in its looks.

Cavagna Kosan 924N RV Auto Changeover Regulator w/RV 'L' Bracket



It "only" flows 160,000 BTU/hr of LP while the standard ME MEGR253 flows 225,000 BTU/hr. However the 160K is more than enough flow for all your propane appliances at once. If you plan on having a Solo Stove/fire pit or other high consumption items, its possible, though doubtful, that you could be limited in flow.

One advantage of the Cavagna is the automatic change over indicator is very easy to see and is also the knob to select the in use tank.

See pages 83 to 101 of this catalog.

Also realize you will need a new hose from the regulator to the piping in the trailer, Examine the existing hose to determine the fitting on the trailer end. The regulator end is 3/8 male NPT. The Marshall catalog has those on page 17.

Hi Charles,
Thank you for this. Yes, I don’t believe I would have any issues 160,000 BTU/hr. I am aware I would need a new hose should I raise the regulator. Probably a good idea to replace it in any event. The current one is approximately 12” with the regulator at the base of the tanks. So I’d need closer to 2 1/2 to 3 feet. Theres a specialty propane shop in my area that sells the Marshall you recommend.
