I have a some questions about the Hayward Sense & Dispense system:
1. When I open the test port, no water comes out. Am I supposed to open either one or both of the effluent or influent valves at the same time?
2, Is the pump supposed to be off when opening the test port?
3. Can I install the return/suction line using the suction drain port at the base of the variable speed pump?
4. Does the Sense and Dispense work with variable speed pumps or should the pump be set at 100%?
