hello all,
So I got a new return pump. Little Giant 3-MDQX-SC, (used to have a 2 series) and I have a 75 gal tank. Needless to say there was some adjusting that needed to be done because the following was going on. Running from the return at about 4-5 feet from top of tank. At 6 ft 875 GPH, should be ok.
1) The overflow was way outta whack. Wasn't allowing water thru the overflow box consistently.
2) The water in the sump wasn't getting high enough.
So I dialed down the ball valve to about 5/8ths and it seems to help balance everything.
Here is my question. How can dialing down the ball valve NOT reduce the flow of water ?? That was my whole point of getting a new return pump, I wanted more water flow. Is dialing down my ball to 5/8ths hindering flow and will it damage anything ?
Can someone please help answer my question and give me suggestions.
