I recently replaced my propane regulator with a Marshall regulator. I also replaced the pigtails with Marshall pigtails. I think there was water in the system and I could see water in the regulator. Marshall is a high quality product made in the US.

I wonder if the propane were not purged before they were filled.

There was visible moisture in the regulator that I replaced. I just assumed that the green/red monitor window was separate from the actual propane. That the moisture in the window wasn't a factor. Was I wrong?

The only issue we had on our PU trip on the 19 was the auto changeover didn't work. However, it was 12 degrees that night and if moisture was in it that would be what happened. There seems to be an above avg failure rate on the stock regulator, so now that we're back in good temps if it fails again, I'll ask ETI to let me select the warranty replacement brand if possible. The Marshall one that Dave installed is similar to the ones I've always had on trailers and never had regulator issues before.

Purging

Trying to fill a new tank full of moist air would not be good idea, and would introduce some moisture which could cause problems.

This statement in the linked document:
Quote:
All new propane tanks (MHs,) and cylinders (Fivers and Travel trailer from 4-40 pounds, which includes BBQ tanks etc.,) MUST BE PURGED BEFORE BEING FILLED FOR THE FIRST TIME!
... is a little extreme, or at least out of date (it was written at least ten years ago). Most of the 30-pound and smaller propane cylinders that I have seen for sale in recent years (from both Worthington and Manchester) have been vacuum purged at the factory, so no additional purging step is needed before first use. It is worth checking this if getting a new cylinder.

Low temperatures are inherently problematic for auto-changeover regulators, because the switch runs on the difference in propane pressure between the two tanks which occurs when one tank runs empty, and even the full side has low pressure at low temperature so there won't be much difference.

While the indicator compartment is presumably not filled with propane, my guess is that moisture freezing in there could interfere with switching operation. It seems likely that moisture in the indicator chamber would be the result of condensation from moist air trapped in there, rather than from contamination of the propane.

On a larger trailer I have the only auto-changeover regulator that I have owned (assuming this the orignal, and I don't recall replacing it), which is a Fairview Model GR-9984; it looks entirely unlike the one illustrated in the Fairview page, but if it is the original it is about 14 years old so I assume that it is the previous version. The current GR-9984 looks like the Escape-supplied original shown by Dave.

Mine was made in India, but I think the location of the factory is nearly irrelevant: although crap can be made in third-world countries more cheaply than it can be made here in the land of high wages, it can be made anywhere... and good products can be made anywhere that the manufacturer is willing to demand high quality, follow the processes necessary to produce it, and pay what it takes to reach it. Certainly "made in North America" has never reliably meant "well made", and almost any auto enthusiast is aware of the era in which it quite consistently meant "inferior to anything made in Japan". Every product from Apple Computer is made in China or other Asian countries, and although I'm not a fan those who are would probably react strongly and justifiably to the suggestion that all Apple products must be junk due to their origin.

Dave
Are you sure it's made in the U.S.? In previous searches I've seen that Marshall sold out to a Chinese company that markets them as Marshall Excelsior.

Other forums allude to RegO 7525B23 as being the only U.S. made one. See it on PropaneProducts.com for $110.

Well- I do see it advertised on EBay with a "Made In USA". Remember that city in Japan? Now if it were made there everyone would be thumbs up

I hadn't heard of Usa, Japan, before, but the "Made in USA" myth isn't a big surprise.

Marshall Excelsior is still headquartered in Marshall Michigan, although of course they could have products made anywhere. The MEGR-253 Excela-Flo Automatic Changeover Regulator is - according to the brochure - made in the USA... if that matters.
