Many owners of their "penates" know about the need to replace flexible pipes with faucets and toilets.
The frequency of replacement of flexible liners is on average five years. Regardless of the external condition. Otherwise, the likelihood of flooding the apartment increases many times.
TESTS
Now I will show you a vivid example of why it is necessary to produce flexible eyeliner as often as possible. And it will help us, in this matter, 100 bar from a pressure washer. For those who do not know, this is a lot.
Earlier, for this case, I invented an adapter, with its help it is connected to an AED gun (high pressure apparatus). And also pressure control is performed.
I took two hoses for testing. One used unit removed from the facility, because the service life has passed. The second new one, the first one that came across. I connected them in series using a "barrel".
I installed a plug on one end. Second to the adapter.
General view of the entire test bench:
Warning:Do not under any circumstances repeat these steps, it may damage the AED equipment. Also, uncontrolled high pressure release, or rupture of pipes and containers can lead to injury.
In order to protect himself, he put on tight overalls and glasses for eye protection.
A little worried, I pulled the trigger of the pistol, a mini sink hummed behind me, DELIVERING THE MAXIMUM PRESSURE. At the same second, a hiss started from the hose and its end flew treacherously to the side, since I was not in the affected area. As a result, the hose that was in use burst. The mark on the pressure gauge was just over 50 bar.
I removed the old eyeliner, and mounted a new one, to the pistol. He did not tighten it for a long time and applied pressure. Steam pressure, pressure gauge-hose has reached 90 bar!!! The peak was over 100.
But the eyeliner didn't burst. The pressure gradually tended to the bottom, water oozed from under the FUM tape, this place was marked in the photo with a green circle.
I was scared go to the hose, there is a chance that it will break when I am next to her. But having overcome his animal stah, he observed an interesting picture. Scroll through the gallery:
The rubber hose was ripped apart very much, thus the braid began to thin. At this point, I began to observe microdroplets seeping through the pores of the rubber. It was strange to watch it ...
As a result, the new hose withstood a five-fold excess of the declared pressure. And the old ones rushed where he should have. Therefore, do not be lazy! And change flexible pipes on faucets and toilet cisterns. That's all Arivederchi ...
