Model overview based on user reviews
The Grundfos SQ deep well pump is highly praised for its durability and quality, with users noting that while the price may be high, it is worth the investment for long-term reliability. One user reported that their previous model lasted 20 years before needing replacement, highlighting its consistent performance in pumping water from significant depths. The pump is also appreciated for its ability to maintain pressure effectively, even when multiple taps are used simultaneously. Additionally, the built-in protection feature is valued for preventing damage when water levels are low, ensuring the pump's longevity. Overall, the Grundfos SQ is considered a great model for those seeking a reliable and efficient deep well pump.
Pros
Cons
We bought the same one 20 years ago, purchased the Grundfos package (a tank with water reserve in case of a power outage (I don't remember the name) and an electric water regulator). The system worked for 20 years, only recently one capacitor on the regulator broke and the pump burned out, but it had no problems pumping water to 2 circuits (house and kitchen) from a well about 37 meters deep. If you're interested in where we bought it, we purchased it in Poland at that time. Durability and quality of the product, the price is a bit high but it's worth paying once and not worrying. We will install a new one exactly the same. They are not there, maybe just the price, but it's worth paying once and not worrying. use Grundfos SQ 3-40 more than year |
At the dacha there is a 10-meter well; a Grundfos submersible well has been installed for two years. It holds pressure, the pump’s performance has not dropped, and it also gives good pressure for both the kitchen and the bathroom. When the tap is turned on at the same time, the pressure drop is almost unnoticeable. Sometimes the protection works and turns it off, this is if there is little water in the well, but it saves the pump for the better. presses well, does not break, holds pressure everything is liked use Grundfos SQ 2-85 more than year |
