Slow the Flow on Siphon?

Yeah, weird concept at first but once you see it in action it will all fall in place.

 

well there you go glad someone came in to correct what I said.

 

Describe your overflow. Do you have an internal or external overflow box? Does it have a standpipe?
The overflow should laways flow unrestricted and the pump will return whatever it is capable of.
Why do you think the overflow is too much and/or the pump too little?
The level in the tank will be determined by the overflow height and will self adjust based on the size of your return pump. If anything most people will experience the opposite problem, too large of a return pump which outruns the overflow.

Noteworthy Points:
Green Light: Return pump ON
Water rises to tank
Return area lowers
Display fills higher
Overflow fills
Overflow drains to sump
Sump fills


Red Light: Return pump OFF
Residual water in plumbing drains
down
Drilled hole in return line

Siphon is maintained in
the overflow box
Sump is tall enough to hold
excess water

 

Use the adjustment screws to raises the intake level up closer to the overall water surface.

 

Alright, thanks guys. The physics involved are starting to make more sense, but I still sense some black magic.
