Flexible hose: reinforced or crinkled
I welcome you to the channel!
Theme selection flexibles hoses extensive, therefore only briefly touch on the question of installation of reinforced and corrugated (bellows) hoses on common Plumbing: faucets, toilets, sinks, etc.
Private and foreign experience shows that among users of eyeliner and other types of more of those who are satisfied with the choice, but there are also those who are not lucky. In the aggregate figures more reliable feel, nevertheless, a corrugated stainless steel version of the flexible liner.
Life time
When high-quality braided reinforced rubber hose run for 5 and 10 years, especially if it does not twist and no permanent condensation on the surface. This sample will stand bellows and all of 20-25 years, and maybe more, the only question as steel, electrochemical compatibility of its various metal parts and so unexpected impact factors as stray currents.
the likelihood of leaks
Since klassnosti best side note bellows hose. But it is likely that both types of hoses can leak. Why? Since the used seals in both hoses are roughly the same, the problem is because of them the same. Leaky seal - no matter what your hose.
grounding
Yes, as part of a less-complex systems bellows hose need to be grounded, otherwise it is likely that the complex nature of the current lead him into disrepair. Some of it is because of that there were problems, including a high-quality products, as stray currents gradually burn up metal holes. Punched corrugated hose made of stainless steel repair is unlikely anyone will.
noise
For many was a surprise that while the bellows hoses buzzing, singing, noise - all associate sounds in different ways, but not all are willing to get used to them. To solve the problem of noise to buy products with a large diameter, which is not always practical. With reinforced hose such surprises do not happen, except that the state of the gasket can let them know about yourself the audible vibration, but it applies to the first hose.
Reaction to hammering
Usually without water hammer in the plumbing is complete. Any sudden closing of the mixer or a ball valve in the tank creates a small pressure surge - water hammer, which both hoses are designed. By themselves, such hydroblows not withdraw the rubber hose down, but if he had already begun to break down, for example, from the excesses or improper installation cracked braiding, hammering it on the sly will bring it to the big break, then simply rubber burst. In this sense, reliable stainless steel bellows.
Flexibility
Braided hose in comparison with stainless steel, more resourceful, but not strictly keeps a predetermined position if, for example, it is necessary to ensure bend 6-90 degrees. Rather, it turns into a semi-circle, or what is worse, to break that affect the strength and permeability of the hose braid. Stainless steel hose, though harsh, allows to fix the angular bend, however small rotation angles make them uncomfortable - a big radius, which "eats" length.
More importantly, the bellows hose through garmoshechnoy structure during freezing does not break, but only a little stretch. But reinforced fellow can hold out in the cold for several years, and may not survive another winter, depending on weather and the characteristics of the system on which it is installed.
cost of
Bellows liner tube is made of stainless steel and it may be a certain length or to fold and unfold in certain limits. Rubber reinforced hose, of course, does not have these and other advantages, so it is cheaper. On average, the bellows will cost twice as expensive.
In general, the choice - it is always a puzzle.
