Getting ready to 'close' my pool for the first winter that I've owned it. SInce I'm in an area that rarely freezes at night, my plan is to clean/shock/algicide/cover the pool and set my timer to run the two-speed pump on low for 1-2 hours every night.
I've been experimenting with the pump and my main concern is that the pump wont prime when the timer turns it on at night. Previous owners (orginal installers) ran the pump 24 hours a day so this wasn't an issue. Should there be a check valve before the pump inlet? Would one make the pump priming easier? The pump primes relatively quickly on high speed but I haven't run the pump more than 30 seconds waiting for it to prime on low for fear of damaging it.
Also, should I set my 6-way valve to recirculate or filter during the winter? Will the filter even be effective or just become air-bound from turning the pump on/off?
