How do you flush a hayward heat pump?

To flush a Hayward heat pump, first, turn off the power to the unit and ensure the water supply is disconnected. Connect a garden hose to the drain valve and direct it to a suitable drainage area. Open the drain valve to flush out any debris or buildup in the system, allowing water to flow for several minutes. Finally, close the drain valve, reconnect the water supply, and power the unit back on.
