Osmolator 3155 ?

I just changed my reservoir bucket from a 5gal to a 15gal and it seems that when the Tunze shuts off(cause it is at the correct level) the water still trickles out of the line. Never seen that in the 5gal bucket. The sump and bucket are at the same level. I don't know how long this will do it cause I pull the pump out to stop the flow. Do you think its a pressure problem being that there is alot more water in the bigger bucket?

It is siphoning. You need to raise the output higher than the bucket it is pulling from. I would recommend topping off the main tank instead of the sump. Do not submerge this line into the tank or you will get the opposite problem.

Another option is creating a "gutter" with a piece of rigid tubing and have the line fill into the open gutter higher than the bucket.

Shawn is correct. The taller reservoir is causing a siphon, you ned to reroute the hose so the end is above the top of the water line in the reservoir.
