Q: I am getting microbubbles in my system. How do I eliminate these?
A: Your pump is picking up microbubbles from your return lines to a sump which is too shallow or small. Install a Dolphin Intake Filter Foam (Commercial Pre Filter) on intake to pump from sump. Make sure sump water level is at least 4" above top of pump level.
Q: My Dolphin Pump is too powerful for my system. Is there a way to decrease the amount of flow without harming the pump?
A: Ball valves should be installed right after the pump intake and discharge unions for easy pump removal, and for discharge control. Discharge flow may be valved back to any flow without pump damage. The more flow is lowered, the less amps the pump will draw.
