Report Joe G in All Swimming Pools Types Posted August 16, 2022 I have a pool with a spa attached above the pool with spillway. My question is can you run the spill way while the spa mode is on. My understand is that it won’t spill over bc it can not take water from the pool. Also when the pool is running I put spill way on and it works great but when the schedule switches to spa mode spill way still stays on. Is that okay?
