hey all was wondering if anyone on here has a quiet one 3000 pump or something that does around 780gal per hour. I bought a quiet one 4000 hh and it is pushing to much water even when i try valveing it down.So was looking to trade for my pump
How are you trying to valvle it down?
Did you just place a ball valve inline from the return or do you have it T’d off back to the sump?
If you T it off you should be able to dial the flow back to a mere trickle returning to the tank.
i just placed a ball valve in middle of the line
Take a look at the attached pic. All you need to do is at a T to the line and you can use that energy your pump is using to keep your sump from getting too low flow and crap settling down. It will help keep everything in suspension so your skimmer and water changes can remove it and it won’t waste electricity. Win win.
PBJ!
If the ball valve is all the way open all the water goes to your sump and none make it to the tank. All the way closed and all of it goes to your tank. In-between you’ll play with and find out.
Precisely!!!
The location of the ball valve can either be where Jon has it in the diagram or on the horizontal pipe out of the T.
Restricting the pump with the ball valve in-line as you have it now can end up damaging the pump in the long run, teeing it off doesn’t restrict flow from the pump but re-directs flow after it leaves the pump.
99% of pumps used in the industry are designed to work with head pressure of some sort. Most of the time pumps are used with at least 4 feet of head pressure to get the water from a sump to the display tank. Restricting the outtake is the equivalent of adding head pressure, and usually won’t influence the pump significantly at all. That being said it is wasting electricity.
On a side note Ting off and heading into a media reactor or a protein skimmer is another way to use this excess power.
I have a 2200 if you’re interested. I just put a 4000 on my system and it turned out to be perfect, I was expecting to need to throttle it back.
