Maid-O-Mist Failure Rate ?

Sure does. Still seems like it would be something they would tout on their website.

Interestingly this seems to be the site of their US Operations on 3217 N Pulaski Rd in Chicago.

I think that is their old location. Their address shows Arlington Heights on their web site

That's what I thought. Arlington Heights.

I bought this MOM #1 from Supply House about a year ago and it’s stamped with Chicago. I haven’t seen any with Arlington Heights yet. I’ve had a good experience with MOM so far. The he price and the adjustable orifices make them so much more attractive than Gorton for me. I’ve heard plenty of people complain about Gortons failing on the forum as well but without the benefit of affordability or adjustability.

Must have made a good stockpile before the move.:) Mine are Chicago as well.

Quick update. Received and installed my new MoM's from Supply House last evening. I forgot how well my system could heat! Much faster heat up times for the radiators and the house overall feels warmer even though it is the same temperature.

The valves that got replaced are only 2-4 years old and definitely were not in tip top shape.

Also they had "Made in USA" on the box…but I forgot to see where they were made in Chicago or Arlington Heights.

Maybe the China reference is misapplied as to changes in quality of MOM vents - it could be in-house planned obsolescence at work,

Planned obsolescence describes a strategy of deliberately ensuring that the current version of a given product will become out of date or useless within a known time period. This proactive move guarantees that consumers will seek replacements in the future, thus bolstering demand.

Just sayin,

I don't think we have any evidence of the quality of any vent, neither in the past, nor currently, to be able to make any claims about that.

We have very minimal anecdotal evidence on a forum where people come explicitly because they are having some kind of problem.

Agreed. Can I now complain about my Gorton and Hoffman Specialty vent failures?

What I can say, with reasonable surety, is that new vents do not last as long as old vents. (Also anecdotal, but I have more anecdotes).

To All, I have tested well over 200 vents from various manufacturers. Mainly the most popular ones. I have purchased them from various vendors. I have many years of experience in test and measurement and design for electronic and mechanical components mostly in the defense industry. There is clearly something wrong with the quality of vents produced in the steam heating industry. I am not referring to failures due to misuse such as high pressure or foreign material. The level of failure that I have noticed is not tolerated in other industries. As my engineering manager told me in 1988, when I asked him how come his prototypes are always close to prediction: Any one can come up with a design, you have to know how to build it and how to test it. Vents are not difficult to produce if you know what you are doing. It is not rocket science. [My last employer was Northrop Grumman]
