The pump’s suction port (inlet) must be lower than the normal operating bath water level to ensure proper pump priming, but higher than the spa bath suction to ensure correct draining. When emptied, the water must drain back into the spa bath as required by Health Department Regulations. b. The discharge port (outlet) should be lower than the water level and the plumbing should be horizontal or rise slightly to prevent airlocks. Airlocks will prevent the pump from properly priming.
