Steam vent life

Member Posts: 20
I've seen several posts suggesting that vents last only 3-4 years. Our one-pipe steam system, in the 33 years we have been here, has had only one vent replacement. The system heats fairly evenly, and the only vent that is not 100% hisses a bit before a not-too-loud click. The only reason I don't replace it is that the sound is comforting in the middle of the night when it is cold outside. Kind of like when the old oil burner boiler (RIP) was kicking on.
Granted, we have soft, mountain water here which would reduce calcium build-up, but what is the story on vent life?

If you don't abuse them -- keep the pressure down -- there's no good reason they shouldn't last a long long time. Same thing applies to traps. And no, I don't know how long is a long long time...Br. Jamie, osb

So I guess vents should last years and years.Single pipe 392sqft system with an EG-40 rated for 325sqft and it's silent and balanced at all times.

I have an original Hoffman #2 vacuum vent on one of my radiators. Still works fine. Original from around 1907. Not sure if it holds vacuum anymore. But its a nice slow vent for a little radiator it on in my laundry room. Had a from others from probably the 60’s that were fine too.
The newer Ventrites I’m using now have some plastic parts that will likely deteriorate in 20-25 years.0
