Pentair Ortega 072523 Check Valve 1lb Spring
I'm needing to replace the seat assembly p/n 073502, on my pool and spa. Two different springs are shown, p/n 072523 1lb, and 072524 3lb. Which spring is correct for use on spa to prevent back flow.

Good morning, Rusty, the 1lb spring should be fine. Depends on the line run and how many feet below the equipment sits. The only thing against you is gravity.
