I have a spa that spills over into the pool. I want about 20% of my return water going to the spa to chlorinate the spa and produce a nice waterfall; thus 80% of the return back to the pool.
When I shut off the pump, the spa drains down to the water level of the pool. I can hear the water trickling by the return valve actuator. I replaced the check valve already and new o-rings in the actuator valve.
When I turn the valve actuator to return 100% to the pool, it does not drain the spa; in this mode, this also means no clean chlorinated water goes to spa and no waterfall from the spa spilling over into the pool.
What am I doing wrong?
