I can't speak to designs as you don't provide an example and Im not in Belgium. A couple of thoughts, from my experience in the us.
Water pressure is not the same everywhere in a city. Some places have very high water pressure, some places have terribly low pressure. It may be worth investing in a pressure gauge. There are adjustable and static gauges that will help manage water pressure.
If you leave your hose spigot on when the hose is not in active use, or even leave water in it. I would advise against this. The sun heats up the hose, increasing water pressure significantly, which can even cause the hose to burst.
Another thought, after doing a quick search. If this is the design you're talking about, then idk how anyone would expect this to last any amount of time unless the pressure was uselessly low. Or maybe us hoses are such crap that I can't compute how this design could function.
