Recently there was a case when they invited me to an application for the replacement of meters. The owner of the apartment immediately told me that he was trying to replace the flow meters on his own, that is, he was trying to save money. But he failed:
- “What I didn’t do, just as I didn’t try and water it with WD, the water meters still did not turn away. I even invited my neighbor to sip the keys. He advised to call locksmiths, citing the fact that you have more experience. "- The client told me with pressure, justifying his impotence in plumbing.
Any split joint on the pipes can begin to oxidize and make it difficult to disassemble the assembly. Metal fittings can oxidize for several reasons:
1) A leaky connection allows water to pass through and over time, with the participation of oxygen from the air, an irreversible process occurs, the destruction of a thin layer of metal. This leads to the formation of "salts" on the surface of the threads that interfere with disassembly.
2) Electrolysis, stray currents in the pipeline, pipes can be scarred to holes. Threads suffer from it and metal heated towel rails deteriorate.
For all the time of practice, it was almost always possible to unscrew the counters. And then the client looked at me attentively, in anticipation that I would suffer. But he shouldn't have expected this, picking up two keys, I managed to unscrew them with ease.
-"How??? How did you do that?"- The man wondered.
The answer was simple - "As I see, you have filled the entire water meter multifunctional grease, so it worked in a day, this liquid was able to penetrate into all the pores and separate the bronze nuts from the water meter with a thin oil film.
Therefore, before changing the oxidized counters, you should fill them with grease from special cans at least a day before. Then exactly cope with the work of a plumber and save money.
Having completed the request, a thought crept into my head. Which WD-40 type grease works best. That is, it penetrates deep into metal parts most quickly? You can, of course, go online and watch reviews. But I always get the feeling that the articles are ordered. Therefore, I decided to independently check the lubricants for their "activity" and find out whether it is worth overpaying for a real WD-40 or a cheap enough lubricant from the traffic light
For the purity of the experiment, multifunctional lubricants, silicone lubricants, kerosene and even "quick start", a liquid to facilitate engine start, were purchased. Why not.
Experimental details I will have nails that I tried to artificially "rust" with the help of hydroperite tablets. Hydrogen peroxide formed in the bottle of nails. Which actively began to corrode metal. All photos with nails are in the gallery.
For three days, the nails lay in a bottle with a mixture of hydrogen.
It's time to pull the nails out of the solution and start figuring out which lubricant is better. I'll tell you about this when I get to the garage. Don't miss the article on the channel.
I have never bothered with articles for so long. I hope you like the plumber's work!
