Grundfos Pumps Editorial Review

The Grundfos 15-178-6291 Low-Flo Circulation Pump is a suitable replacement for spas and hot tubs circulation pumps. It requires flooded suction, has a water flow rate of 12-18 GPM at 0 PSI and its barbs are not removable. Although the power cord is sold separately, the pump has received positive reviews for its performance, efficiency and quiet operation. However, some customers faced issues with broken or rattling pumps and mentioned that the outlet location is inflexible, making the replacement process a bit tricky. Others wished the pump had 3/4" barbed adapters. Overall, it seems to be a reliable and effective pump for spa and hot tub owners.
