I was scared, as it was a bit unconventional, but took the plunge as the specs were better than the more conventional and expensive grundfos models.
Instructions are a bit criptic and scare you a bit, but after you have done one, the second would be a doddle.
Order was placed on Sunday and the pump arrived on Monday ! Amazing. Installation was easy, the pump is beautifully quiet. The LCD screen displays the pump pressure, motor rpm and kilowatt consumption. The pressure set point is easily adjustable as well as the cut in differential. Was also over $300 cheaper than the quoted price from my local pump supplier ! Couldn't ask for better service or product !
The pump arrived in record time, really impressed with the delivery! The manual that came with the pump was anything but impressive, however a quick email resulted in a very comprehensive PDF manual. Pump set up was dead easy and it works really well without any changes to the factory settings. Extremely quiet when operating and good constant pressure. I am looking forward to see if the variable speed motor results in energy savings. A good buy!
Mine is installed in pump house outside, it provides silent consistent water pressure to as many taps as I can use, gone is my water hammer. This pump even looks as good as it works. The multiple outlets allowed me to match existing pipe work. Delivery fast also.
