Message: [QUOTE="Gordo33, post: 324045, member: 7972"] Thanks for clearing that up In the set up with the BD line going thru the liner to the SC is there enough flow to pull debris especially larger debris up and then across? From what I read a true BD pulls water from a large radius from the BD location. For ex a 3 inch BD will pull debris up to 8 feet away. Do you know what the radius for debris being drawn to the BD for the pic you attached? Also how do you determine pump size for this set up. As you stated in a post here there are set flow rates based on diameter of the true BD. With the set up going up and over the pond to the SC. The inverted U shape created by the tubing looks similar to aquarium over flows. My understanding the water flow is via SIPHON and is dependant on removing all the air from the inverted U. The issue with this set up is air can accumulate in the tube and potentially break the siphon . This would cause the pump to drain the SC and then the pump would fail. In the event of a power outage I assume the BD would continue siphoning the water into the SC draining the pond as the SC over flows. Unless the bottom drain is pulling water from a large radius and can move large debris upward and across to the SC , I don't see the advantages of the pictured set up to the above liner BD set up I use.
