Review of Grundfos

I have been fitting Grundfos pump for many years. Based on their reputation as market leading pumps.
Since the introduction of GRUNDFOS UPS3 15-50/65 we have had replace at least 5 faulty pumps in the last year. These pump were either under 1 Year Old or 2 max. These have been replaced at the expense of my business both in time and replacement pumps.
At this point the penny has dropped that these have design fault and will have no choice but to find alternative manufacturer. I hope Grundfos are a company that realises that they have problem and need to make changes or their reputation will really suffer.
