Subreddit guides combine public Reddit source URLs, captured rules, visible verification dates, and Rankhog's account-safety workflow.

Rule summary

  • No Spam: You should not spam in any way.
  • Civility: Remember the human. When you communicate online, all you see is a computer screen. When talking to someone you might want to ask yourself "Would I say it to the person's face?"
  • On-topic: Content and discussions should be related with Maintenance, there are other places for other discussions.
  • Effort: This subreddit is for helping each other to solve real-world problems, share expertise, and learn. Posts and comments should show effort and relevance. Content that lacks context, technical detail, or does not contribute meaningfully to discussion may be removed.
  • No CMMS: The community don't want CMMS promotion and research here.

Works well

  • A detailed troubleshooting post that names the equipment, the fault symptoms, and what you already checked before asking
  • A story about a breakdown you diagnosed and fixed, written so the next person facing the same fault can follow your steps
  • A comparison of preventive and predictive approaches on a machine you actually maintain, with the tradeoffs you saw firsthand
  • A specific question about vibration analysis, oil sampling, or another predictive technique, asked with real data and context
  • A thoughtful answer to someone else's maintenance problem, showing your reasoning instead of just naming a part
  • A question about maintenance planning or scheduling challenges, framed as seeking experience from people who live it

Avoid

  • Promoting a CMMS product or asking the community to take part in CMMS research, because “No CMMS” makes that a removal on sight
  • Dropping a link to your maintenance software with a line like let me know what you think, which reads as spam under “No Spam”
  • Posting a vague question like how do I fix this machine with no machine type, symptoms, or what you already tried, which fails “Effort”
  • Starting a thread about something unrelated to maintenance just because the community is active, which breaks “On-topic”
  • Getting sharp with someone who disagrees with your diagnosis, which risks trouble under “Civility”
  • Writing a post that is really an ad for your company dressed up as a question, which the moderator one-liner says gets removed as spam

What r/IndustrialMaintenance Is For

This is a community for people who work in industrial maintenance. The description says it plainly, they share experiences and knowledge on industrial maintenance, and they name three flavors, preventive, curative, and predictive. The people here are technicians, reliability folks, and maintenance managers talking about real machines and real problems. The “Effort” rule tells you the purpose out loud, it is a place for helping each other solve real-world problems, sharing expertise, and learning. So if you spend your days around pumps, motors, conveyors, or maintenance planning, this is your room. If you spend your days building software for that world, you are welcome to learn here, but you are not welcome to sell here.

Rules That Matter Before Posting

Four rules decide most outcomes here. “No Spam” is the first wall, and any post that exists to push something will be read as spam. “No CMMS” is the unusual one, and it is worth reading twice, because the community does not want CMMS promotion or CMMS research in any form, so a software founder in this space has to stay completely out of product talk. “Effort” is the quality bar, and it says posts and comments should show effort and relevance, and that content without context or technical detail can be removed. “On-topic” keeps the room focused on maintenance, and “Civility” reminds everyone to treat people like humans. The moderator one-liner sums it up plainly, they remove spam, off-topic posts, low-effort questions, and any CMMS promotion or research.

What To Post

The safe and useful play here is to be a helpful technical voice, not a marketer. Ask a real maintenance question with full context, like what the machine is, what it is doing wrong, and what you have already tried. Answer other people's problems with the depth of someone who has actually turned a wrench. Share a lesson learned from a failure you dealt with, told as a story with the technical details in it. If you are a founder in the maintenance space, your product is off the table entirely, so your credibility has to come from genuine expertise in the craft itself. Write posts that a technician could learn something from, and you will earn a name here.

What To Avoid

The fastest way to get removed here is to bring CMMS talk into the room. The “No CMMS” rule bans both promotion and research, so that means no asking people to test your software, no surveys about their CMMS workflows, and no what do you think of my tool posts. The second fastest way is spam, which the “No Spam” rule bans in any way, so no link drops, no drive-by promos, no dressing an ad up as a question. Third is low effort. The “Effort” rule says content that lacks context, technical detail, or does not contribute meaningfully may be removed, so a thin question with no details will not last. Fourth is going off-topic, because the “On-topic” rule says there are other places for other discussions. And keep it civil, the “Civility” rule asks whether you would say it to the person's face.

Common questions about r/IndustrialMaintenance

Can I post about my CMMS software here?

No. The rule “No CMMS” says the community does not want CMMS promotion or research here, so any post about your CMMS product is out.

Can I mention my company at all?

Not directly. Promotion is conditional here and CMMS promotion is banned outright, so the safe move is to help people with real maintenance problems and let them find your profile.

Can I ask for help with a maintenance problem on my own line?

Yes. The description welcomes preventive, curative, and predictive maintenance, so a genuine technical question with context fits fine.

Are links allowed?

The rules do not say links are banned, but they do say no spam and they demand effort and relevance, so only share a link when it genuinely helps the discussion.

What is the general vibe of this community?

It is a working community of maintenance people sharing experiences and knowledge, so expect practical, hands-on discussion rather than marketing talk.
