I chose this on-press for its quality / price ratio (assumed), this in light of previous comments. Once the installation I noticed a small leak in one of the fittings, I have not had any luck it seems ... Difficult to obtain warranty on it when you really need a new pump in emergency to restore water at home. Otherwise it does the job it says 76 decibels but the noise it makes is more acute than my old pump, and there I notice more. The advantage of the stainless steel material of this group is to prevent its slow degradation by moisture.
