An unofficial chapter of the popular Dull Men's Club.

https://dullmensclub.com/

1. Relevant commentary on your own dull life. Posts should be about your own dull, lived experience. This is our most important rule. Direct questions, random thoughts, comment baiting, advice seeking, many uses of "discuss" rarely comply with this rule.

2. Original, Fresh, Meaningful Content.

3. Avoid repetitive topics.

4. This is not a search engine
Use a search engine, a tradesperson, Reddit, friends, a specialist Facebook group, apps, Wikipedia, an AI chat, a reverse image search etc. to answer simple questions or identify objects. Also see rule 1, “comment baiting”.

There are a number of content specific communities with subject matter experts who can help you.

Some other communities to consider before posting:

5. Keep it dull. If it puts us to sleep, it’s on the right track. Examples of likely not dull: jokes, gross stuff (including toes), politics, religion, royalty, illness or injury, killing things for fun, or promotional content. Feel free to post these elsewhere.

6. No hate speech, sexism, or bullying No sexism, hate speech, degrading or excessively foul language, or other harmful language. No othering or dehumanizing of anyone or negativity towards any gender identity.

7. Proofread before posting. Use good grammar and punctuation. Avoid useless phrases. Some examples: - starting a post with "So" - starting a post with pointless phrases, like "I hope this is allowed" or “this is my first post” Only share good quality, cropped images. Do not share screenshots of images; share the original image.

I replaced my water installation some weeks ago. The copper pipes did not show build-up. I cut the pipe at the hydrofor to make it easier getting it up the stairs that was another story. I think it's 45 years of build-up

Just imagine how all the water you drink flows through there.

[–] redlemace@lemmy.world 17 points 5 days ago (1 children)

I do ....

all the water you drink flows through there

That's not the point... The water itself is! Where do you think the build-up comes from ?? However, we regularly send samples to a lab to ensure it's healthy, and it is. I'm also a 100% sure the pipes from whichever water company has build-up in it too.

[–] ikidd@lemmy.dbzer0.com 14 points 5 days ago (1 children)

Hard water minerals like calcium and iron. It's not harmful.

And a little bit of Al and Mg as well. All of those metals that could have been in your bottle or shower are now stuck in the pipe walls. You're really missing out.

[–] BoxOfFeet@lemmy.world 4 points 4 days ago (1 children)

Not anymore! Just get a spoon.

Spread it on crumpets for tea.

It's iron oxide. You need that to live.

[–] SatansMaggotyCumFart@piefed.world 1 points 5 days ago* (last edited 5 days ago) (1 children)

That's more than just a bit of rust bud.

[–] altphoto@lemmy.today 4 points 5 days ago

Cmon, lick it! It's for strong bones.

This build up can be the only thing keeping you from drinking lead too. I believe damage to the buildup due to a reduction in water additives was what happened in flint.

[–] snooggums@piefed.world 4 points 5 days ago (1 children)

That is correct, the change in ph eroded the buildup in Flint which allowed the lead to start leeching into the water.

[–] Mouselemming@sh.itjust.works 2 points 4 days ago

100% correct except it's leaching.

No leeches were involved

Yes, that is how the minerals deposit in the first place.

I would recommend you to talk with a hot plumber in your area, as they might tell you what's causing the build-up.

Probably not helpful to you, but if someone has an issue with lime build-up:

but I live in a limestone-heavy place (also known as HARD water 🎸😎) and pipes are more choked than my heart arteries. That said, I tried many stuff (cleaning vinegar, cleaning vinegar + baking powder, specific products, etc.) and from all of them the best has been citric acid: There is a huge difference in quality between products, (not represented by price!) but by concentration, get the cleaning type not the food type.

What I do:

  • Turn off the main and drain the lines. (Turn off all filtration stuff)
  • Get a five-gallon mix in a bucket with warm or hot-ish water.
  • Use a high-point access to let the solution in.
  • Let it do its thing for a morning (e.g. 6 hours maybe but 4h also will do the trick).
  • And then flush it, flush it GOOD.

For the hard stuff, there's sulfamic acid, but so far I never needed it, and it is not so good for PVC or PEX. If someone is desperate and using PVC, muriatic acid can do wonders (and a lot of damage).

None of the plumbers in my area are sexy

[–] skulblaka@sh.itjust.works 6 points 5 days ago

Be the change you wish to see, that's a market opportunity

[–] redlemace@lemmy.world 3 points 5 days ago

Thnx, I'll keep it in mind

[–] Janx@piefed.social 3 points 5 days ago

All I have in my area are hot milfs, apparently.

[–] LadyButterfly@piefed.blahaj.zone 2 points 4 days ago (1 children)

I really like that copper colour, I'd love to have hair that colour. Don't understand the pipes but but dammit good colour!

[–] redlemace@lemmy.world 1 points 4 days ago

hair that colour.

..... mind wanders back to my first girlfriend ........

[–] cholesterol@lemmy.world 1 points 4 days ago

Aw yeah my kind of pipe.

[–] Arcanepotato@crazypeople.online 1 points 5 days ago (1 children)

Is that a lead pipe?

It sounds like you already know it's not unexpected or harmful but if it's lead it's especially positive lol.

[–] redlemace@lemmy.world 1 points 5 days ago* (last edited 5 days ago) (1 children)

lead pipe

Nope, iron (i think). Apparently It's much more sensitive to build-up than the copper pipes.

[–] worhui@lemmy.world 3 points 4 days ago

Oh that makes perfect sense. Iron pipes have a useful life span. They slightly corrode grab on to minerals than corrode a bit more.

I have had to replace my piping and heard that they have around a 40 year service life. The pipes in my house were 70 years old.

Copper is more expensive, but doesn’t need to be replaced every 50 years.

If you have the chance to replace sections of pipe while the walls are open it makes sense to, otherwise just know it’s on the horizon and wait until you aren’t happy with the water pressure. It could be decades more before you notice a supply side issue. That pipe look beefy even with with restriction.
