I recently put up a best way above ground pool and the manufacture told me to only run the pump for about 8 hours instead of 24/7 like the bigger pools do, but my issue is I put a timer on it but the GFCI on the pump chord keeps flipping every time the timer shuts off the pump so I have to go back out and reset it every time. Is there a timer that will work with without flipping the GFCI every time. Thanks
