Overflow Box Problem
My buddy built a overflow box. We are using a 3/4 bulkhead on the box. It is not syphoning enough water to keep up with the pump. What are some ideas to fix this. We are debating making a new box with a bigger syphoning section. Attached are some pictures to look at. We are using a Mag drive 7 pump. We could put a ball valve on the pump but i really am against that. We are going to try today putting another syphoning tube in the overflow to see it will keep up.

In reality you have two options. Build a larger box that will carry more water with a larger drain of install a smaller pump.
You can throttle the pump back with a valve, however, as I suspect you know that's hard on the pump long term and not recommended. Good luck with your mod. Last edited by nwinverts; 02/27/2011 at 03:29 PM. |

Thank you
We have decided to make a larger box with two drains. |

FWIW - IMO, drain size should be no smaller that 1 1/2" in all but the smallest of tanks. Also - not only does it do NO HARM WHATSOEVER to put in a ball or gate valve to temper the output from the pump, it will actually use LESS electricity. It is no different than increasing the height of the return.
