Water level controller 5017

After the pump shuts off I still get flow. I guess it's siphoning some how. I have the hose coming up from in the reservoir to the top of the inside of the stand and then back down to the sump. I figured raising the hose up would break the siphon. Any ideas?

If the bottom of the hose is lower than the water level in the reservoir, it's going to create a siphon regardless of how high the hose goes. I had the same problem. Here's how I fixed it: I have my airline tube dump into a larger tube pretty close to the top of the tubing arc. This allows me to control where the water enters my sump via the larger tube, but not create a siphon because of gravity. Does that make sense? I can try and get a photo if needed.

I get it. Last night I almost learned the hard way. Went out and came home to my sump almost full. I raised the output hose and now when it kicks on and off the flow stops. Thanks for the reply.

Yes, if I recall from researching this, you would need a 33ft high loop to break the siphon, that is the point where resistance would exceed the force of gravity, practically speaking, it is impossible to break a siphon by a loop.
