Ventured into buying this model to replace another pump. This one makes a bit more noise, which doesn't bother me because it is situated outside in a shed. Pumps water from my reservoir, and sets the entire home at 4 bar without difficulty. Easily adjustable: maximum pressure as well as the switch-on pressure. The pressure valve ensures that the pump doesn't switch on instantly when water is used briefly. My old pump didn't have this feature. Definitely an advantage. Unfortunately, haven't found how to set the pressure in the supplied manual. Need to look this up online. Great price-quality ratio. Time will tell whether the pump lasts.
