Basic Water Pump Q's

[IRoman]

a better way is to put a T pipe over the output of the pump and instead of restricting the flow, channel the excess flow back into the sump using a ball valve on the T. That way it doesnt creat unnecessary back pressure on the pump (which can increase heat and wear/tear on the pump).

How strong is the flow out of your return? Is that the mag 9.5?

That sounds pretty smart, I just got back from the store too

Its a mag 9.5

What excess? his pump is starving...and this is a centrifical pump, there is slip in the flow anyway, heat buildup is negligible, all he has to do is put that ball vave after the pump and close it very slightly...the same as increasing the head (back) pressure. That pump was designed to pump more head than the 3-4feet he has now...I would NEVER advise anyone to make their equipment wear out prematurely...I would however not advise sombody about something that I did not have first hand experience with...Zennz

I went ahead and just put the valve on the return line. Im going to build stand in a few months and give it more hieght than this one has. This one was given to me, thats why I used it. (Im still happy with it though)

...Its odd, I would have never guessed the hieght of your stand plays an important part in the use of your equipment

Well with the valve always the closed....it still does it

Im guessing this is a very strong pump. Do I need more bends in the PVC piping?

This is going to drive me nuts, I want the tank to start to cycle so I'll be closer to getting my O's

I think I just figured out what part of my problem is, The clear tube between sump and the pump. It gets air inside of it and the pump looks like it has a hard time actually getting water through it. I'm moving the pump directly onto the sump

that is a good idea...and make sure the water level stays above the outlet on the sump to that pump...when you start the pump again, unplug it momentarily so the syphon from the outlet line starts and back flushes the air into the sump then plug it in again...

Even with the valve on, and almost closed, it still seems to have the same problem. The pump is taking water faster than it can get it. When I balance the flow out with the valve, the pump makes a chattering noise.

At this point, I think If I had more overflow, I could balance out the pump better. When the pump is taking water faster than I want it too, its as quiet as can be and the flow looks good coming out of the return line. When I balance it out now, the return line barely pushes anything in the water.

Should I just build another Overflow and then attach them with a T. Zen, I think you suggested this to me earlier and for safety. I didnt do it because I thought I would be okay but now I think I should do it so I can create more flow into the sump so I can possibly get a better balance

Here is the setup now

Can't hurt to try.

How big is the overflow pipe now, i can't remember?

1"

Do you think having 2 would add more flow?

 

[gomezladdams]

Yes you need to increase the input to your sump another or bigger overflow is the only way to do that.
