Moving the rez from the top of that shelf just above it to the floor totally stopped the siphoning. I think you gotta get the pump below the drippers or they'll keep dripping all the time until they hit that levelQuestion for you hydro peoples: Will check valves prevent siphoning from the res?
Would be happy to meet for a Rangers game
this may help but the check valve did not help me I need drip emitters installed to stop siphoning
.. If anyone knows how properly plumb and hydro rez links, pic, videos, anything will help us all
