I have a question on my solar panel install. Does the three way need to be "leaky"? I have a spare Hayward 3 way and actuator that I planned on using. Is there really a reason to allow the panels to drain thru the 3 way since I run my pump 24/7. I thought I read some place that it is bad to leave water in the panels all day but I dont see any way around it. I may be over thinking this. Lines to roof are all sloped back towards pump and there are manual low point drains for winter draining
Thanks
