The previous owner of my house/pool ran their pump 24/7 even though the math works out to be a 7hr turnover. To save electricity I am looking at doing an 8 hour daily run. One thing he told me when he showed be how to do backwashing is that he hurries up and powers down changes to backwash mode and then restarts so he doesnt have to reprime the Hayward pump.
I have the superflow and tried it once and it does prime itself after about 15s (he was using local shutoffs to close, fill water then startup so it was never dry).....This pump is suppose to be made to self prime but is that daily 15s really hard on my pump (does it get really hot)???? The only damage I could think of wouild just be seals due to heat. Should I add a check valve to stop the return of water upon shut-off....This task would make an extra hurdle at season close (blow out lines).
Any advice on if I need a check valve?
Second question......I know its recommended to add the chemicals at night due to sun breakdown, but everyone says to run the pump during the day. I want it at night to circulate chemicals....What is the best time of day to run those required 8 hours in my case and the corresponding add chemical times?
