3/4 inch drain solenoids - how fast does yours drain?
I'm working on an autofill/drain system and my 3/4 drain solenoid is providing very slow drain rates, I'd estimate 50-60 gallons/hr compared to about three times that without the solenoid inline.
The drain is running to my basement from the upstairs, tank water level is 4 ft above the floor and the the drain is on the floor so I'd estimate the pressure at 15 ft * 0.433 psi/ft = 6.5 psi. The solenoid is rate to 1 psi to function so I'm gathering that its running fully open. When complete the drain solenloid will be taking a portion of whatever the outlet pressure of a Fluval FX5 is, I'm guessing 5 to 8 psi based on things I've seen on this and other boards. I know others have run booster pumps for such duty, I'm not pumped to do so, and my drain rate isn't absolutely unlivable but I'm trying to get a good sense of other people's experience. |
