Review on π¦ Grundfos SCALA2 98562818 3-45 AVCBDF 1x115V 60Hz Auto Water Pressure Boost Pump by Wiktor Jakuta α
I definitely recommend buying, I didnt notice any disadvantages.
1) Hydraulic accumulator (GA) after the station does NOT need to be installed. The station is sharpened to maintain stable pressure, the difference between the top and bottom is only 10%. This means that the accumulator will operate at 10% of its volume. For example, with a HA volume of 20l, the station will turn on after a water consumption of only 2l. At the same time, after the withdrawal of water, the station will pump up the GA for several more minutes. Those. the effect of additional HA is highly questionable. 2) The minimum noise level is achieved with correct installation, i. E. you need good fasteners, gaskets, etc. If you just put it on something hard, it will vibrate. 3) For complete silence, you can make a casing for the station. There will be no overheating, because. the station is cooled by flowing water.
- Fully meets expectations in all respects - in terms of performance, noise level, etc. Good quality product, even the sound of the engine is pleasant - clear, smooth) Very happy with the 5 year warranty. Service engineers are friendly and available for communication. Nothing broke - called for advice. Features of practical use, see below in the comments. 1: It leaked after 2 years of operation, was replaced with a new one under warranty.
- No major deficiencies have been identified. There is a wish to the developers - if it is technically feasible, it would be good to set up the station so that it turns off immediately after the withdrawal of water is stopped. Now it continues to work for some time after closing all the taps. As of January 2022, there is a problem with the supply of spare parts for repairs, therefore, in the event of a breakdown within the warranty period, the station is simply replaced with a new one at the ASC. It is not clear what to do in case of a breakdown after the warranty period, as well as in situations where the case will not be recognized as warranty. When contacting the service, they insistently require the original warranty card (with a unique printed coupon number on the cover). Without it, the service "Service 24 hours" does not work. When buying in online stores, a coupon is often not included at the time of delivery, it must be ordered after (for example, when buying at aliexpress LLC). In general, it is better to have a coupon, otherwise the service is OK.
