Review on Under sink filter Atoll A-550m STD 1/2" white by Stanislaw Stan Stras ᠌
A nice option for the money, one of the best deals.
This system has 2 names: Atoll A-560Em and A-550m STD are one and the same (even both are indicated on the box at once). In fact, just another slightly ated modification of the well-proven A-560E / A-550 Max. Everything that is written on the market in reviews about them is 99% true for this model as well - all these are systems with a mineralizer at the 5th stage. You can also read about the A-550 std - again, almost the same thing, only instead of a mineralizer there is a carbon post-filter, and structurally everything is the same. Despite all the shortcomings listed, mainly related to installation and maintenance, I can still sincerely recommend anyone to install such or a similar system at home. Concerns about the unreliability of connections, most likely, are purely speculative. I read that some advise installing an Aquastop valve at the entrance to the system, which seems to be supposed to automatically shut off the water supply in the event of a leak. Personally, I don't think it makes any sense. I even bought it, but in the end I did not install it. For the sake of interest, watch the video on the website of the manufacturer of these valves - it works only if the pressure after the valve is significantly lower than before it, i. E. when the water begins to flow out absolutely unhindered, it really whips. In practice, even if you just open the faucet with an aerator, Aquastop does not work, because. there is some non-zero pressure in the segment from the valve outlet to the aerator. And in the sabzhe system there are already 5 filters, the tank is filled per hour by a teaspoon, imagine what resistance the water meets all the way inside the system? And look at what a thin stream of water flows from the tap, if you turn off the tank. Aquastop simply does not recognize such a weak leak. I don’t know if you want to - put it on, but there will hardly be a real protective effect.
- 1. The presence in the house of a constant source of drinking water. It seems trite, but if you ever suffered because you forgot to order the delivery of bottled water on time, you will understand what I mean. 2. There is confidence that you are drinking really clean water, because. everything is clear and understandable: such water was at the inlet, such was at the outlet. And who knows what and how is poured into imported bottles? 3. Water has become noticeably softer and tastier. Noticeable immediately, from the first glass - the taste is completely different. I don’t know what affects this more: the quality of cleaning from impurities, or the final mineralization. Apparently, it's both. I have not tried water from similar systems, where at the 5th stage there is a carbon post-filter instead of a mineralizer, but many write that there is quite a distillate at the exit. Therefore, in order to preserve the natural taste, I decided to take the option with a mineralizer for myself. 4. Clear instructions. You can actually do the installation yourself. All connecting tubes are colored, which is convenient for self-assembly - you will not mix them up. All internal wiring between the stages is already done, you only need to connect the external colored hoses. But the filter elements (all but one) will have to be installed independently, but this is not at all difficult. 5. ated crane - more reliable and prettier than in previous series. 6. With a high degree of probability, a pump to increase the pressure at the inlet is still not needed. I live on the 9th floor of a 12-storey building - everything works like that. Measured - in the water supply system, the minimum required is 3 atm. there is stable, while the tank is filled somewhere in 1.5 hours, and the pressure from the tap is quite normal. 7. I expected that the system would make all sorts of noises, murmur, etc. , but this is not even in sight - perfect silence even when filling the tank and draining the "technical" water into the siphon. At least without a pump - there are no extra sounds.
