Is this good flow?

[AquaForge]

I have a Current eFlux pump 1900gph. Just finished my plumbing and leak testing the system with freshwater. My sump is 20 gallon tall. I’m using 3/4 pipe. Here is a shot of the return flow. I filled sump to brim and it’s taking about 7 mins to get to top of the pump head. No bubbles past the 1st baffle.

To be precise,You can calculate your gph with a chronometer and a ml grade container... kitchen cup etc...

Edit: forget kitchen cup lol, use a bigger container... 1-5gallons bucket etc...

That’s not 1900gph which is good. 1900gph through a 20g sump would be whipping.

I have the pump turned up to max

Is it 1/4” plumbing or lifting 10’? Sure it’s not 1900lph?

GPH and about 3 feet

I think yoyr are in the 171gph ?
Nvm i calcul for 7min to fill 20gallons

How high up is the return above the sump?

Do you have the head vs flow chart available for you pump?

What you’re describing doesn’t seem right for a 1900gph pump unless you’re operating it with either way too big a height to pump up, or have valves somewhere that are partially shut.

Give it a good shake or turn it off and right back on. Could be vapour locked. That’s way too little flow though and seven minutes to prime is nuts. Based on images alone I would suggest about twice that flow rate.

general plumbing picture could help to

Here is the plumbing. The control box wont live there I havent done my wiring yet this was just for testing. I closed the valve because the one way valve didnt do its job and water was flowing back into the sump. Thats for a different thread

 

[The_Paradox]

In that picture the valve is closed.

In that picture the valve is closed.

I closed the valve because the one way valve isnt working. Gonna check it to see if that may be an issue too. It didnt close so the water was flowing back into my sump.

Model 6010 ?

The pump is 3.5 feet away from the return in the tank. I am using 3/4 inch pipe so its all within spec. Gonna have to figure out what the issue is. I am leaning towards the 1 way valve.

Keep the return nozzle out of the water slightly to prevent back siphoning. I would not rely on a check valve. Since the check valve is not working I would look there. If that’s not the issue, pull the pump out and test it free in a bucket of water.

Fixed it! It was the one way valve. It was stuck closed. I took it out in un-stuck it and put back in.

I didnt want to use one at all but many people convinced me with the height of my return and my sump size I had to run one. Anyway its fixed now and man that water is scooting out!

Great! Looking better now
