I have a check valve on my system right above the pump. If the tank ever lost power it will keep the water in the piping instead of dumping into the sump.

+1, Otherwise as long as part of the end piece of the locline is above the bottom of the overflow (the lowest waterline when the pumps are off) it should break the siphon. I have a Y adapter on my locline and one end is completely submerged and the other breaks the waterline just a hair and all is good. FYI I learned this lesson the hard way, thankfully my sump is in the laundry room so the waterfall that ensued went down the drain.

that's the problem it has flooded twice. I put a small hole but than it was making bubbles in the DT. than the overflow siphoned out also because it is temperd glass so I have a large pump from the tank to the sump and two smaller pumps returning. im going nuts to figure something out that's not gana give me bubbles in the DT.

Wait, I am a little confused about your setup. You have a pump pulling water from your DT to your sump and then 2 pumps in your sump returning the water to your DT? I didn't understand what you meant about tempered glass?
I got rid of the hole I put in the locline too because of some microbubbles, but as long as part of the end of the locline is exposed above the water at the minimum water line then the air that enters should break the siphon. One thing I could think of it that the PVC connecting your locline to your bulkhead isn't sealed allowing water to slowly leak in and if for some reason your overflows aren't completely water tight that would allow all the DT water to eventually reach your sump. Maybe a photo or a little more clarified detail will help us get this problem resolved for you.

the little hole would spray water out when the pumps are on no? the little jet hitting the water causes bubbles. u are right if it is under the water it would not so you are saying do it just under the water line so after a little siphons out it will stop? the tank is temperd I cant drill it. so everything has to go over the back. i had put a hole but it was above the water line and shooting into the water making bubbles.

Just keep your locline right below the surface of the water, so when it starts to drain it will expose the end of the locline allowing air into it. This will break the siphon and your problem should be solved. Otherwise you can drill a hole with the same idea of just below the waterline and when it drains to the level of the hole it will take air in and break the siphon. Remember to check the whole from time to time as it can become clogged. The first way I mentioned is easier unless you specifically need your locline to direct flow in a certain manner then use the drilling a hole method.

Like Jon said. I have a y adapter to my return over the top with locline. My loc is just below the surface of the water and the siphon breaks when pump is shut off.
