for future plans , i had this design in mind i thought would share and get some more ideas/discussion , it should work same way as conventional BT as there will be syphin in the pipe it will be gravity fed . there are some ready made versions too i found out later-onAre you planning a retro fit BD?
Do not confuse flow rate with velocity. Flow rate is the amount of water flowing through a pipe in a given period of time. Velocity is the speed of the water.
"Volumetric flow rate is the volume of a liquid that passes through a given surface per unit time. It is found from the flow velocity and the surface area of the surface through which the fluid passes."
Boundless. “Flow Rate and Velocity.” Boundless Physics
"Flow rate and velocity are related, but quite different, physical quantities. To make the
distinction clear, think about the flow rate of a river. The greater the velocity of the
water, the greater the flow rate of the river. But flow rate also depends on the size of
the river. A rapid mountain stream carries far less water than the Amazon River in Brazil"

The same flow rate will have a higher velocity in a 2" pipe than it will have in a 3" pipe.
