Been coming here for months now and Grundfos really knows their water and pump solutions sha. The equipment quality is solid and the guys actually understand what they selling unlike some places. My only issue is how long it takes to get feedback when you inquire about something, I waited almost a week for a reply to my message about a pump system I wanted. Overall though I rate them, just wish they move faster with customer inquiries because na that one de frustrate me small small.
