Iron is becoming more expensive, and this factor affects all spheres of life, they began to replace steel where possible and where not. Now I will show you a vivid example of optimization in this regard in plumbing.
Hello friends, "Timofey Mikhailov" is with you. Plumber with 15 years of experience. Now I will share with you my surprise and indignation.
Not a single apartment is complete without mixers, almost always "flexible connections" are used to connect them, a great thing that facilitates the installation of mixers.
From my own experience, these hoses can last 10-15 years, but it is better to change them periodically, every five years. During this time, most of the liners do not have time to get physically tired, but even from that time on, reliability begins to fall. That's all there is to know about them, an ordinary man in the street. But recently I encountered hoses that I strongly do not recommend for installation, let's start in order.
Recently I needed a flexible eyeliner, I went to a hardware store. There were ordinary hoses on the counter, but a novelty riveted my eyes. Interesting eyeliner, with protection of the metal braid from external influences.
Wow, I thought, cool thing, great idea, to additionally protect the metal from external aggressive influences. Which, according to my guesses, can extend the life of this weak link in the plumbing.
Heading to the checkout to pay for my new purchase, I felt a treacherous lightness in this product, in comparison with ordinary eyeliners, I felt a catch. But he did not exchange the hoses.
Arriving home, I was "gnawed" by the thought, what if there is not a metal braid, let's cut it open and check it. On the other hand came the voice of greed, if I spoil it, cut it, it will become useless and money would cry ...
Curiosity took over:
I took a knife and cut off the top cover of the hose.
The braid of the hose is now clearly visible. It became curious, and if you cut it with a knife, then what happens. The metal blade will not take, and everything else will be cut, so he did:
To my surprise, the blade stuck treacherously into the sheath:
Scroll through the gallery, nylon braid, metal imitation. Whether this was done deliberately to mislead or such a production technology, I don’t know. But as a plumber, I can say one thing, it is better to pass by such products and buy eyeliner only in a real, stainless braid, from proven companies.
