you just submerge your return line in the water however deep you want but put a hole in the line about 3/16th-1/4 in down in the water. So that if it starts sucking back it wont suck that much.

There are two small holes drilled on the bottom of the PVC Sched 40 threaded fittings that the loc line screws into. It that enough to break the syphon or should I drill another hole in the first segment of loc line?

Take a picture so i know what youre talking about. Its on the return line that goes into the tank right? You just need one. Once it starts sucking air it will break the siphon
