[shalon]

i have been taking a break for the hobby for to long and have forget most of the thing that i need to remember so am a beginner once again. i was wondering what size pump should i use on my 10 gallon sump

question is how much flow does your drain or overflow handle. and you have to take in account the head pressue and the turns the return water with be facing.

I have the same question... I have a overflow for my 55gallon the pump i purchased was an aquavis 4900 est. to pump 1300+ gallons... but my over flow is not sending down anough water to keep the pump submerged... I was told to buy a bigger u tube or downgrade the pump...

Remember that a 1300gph pump doesn't necessarily pump that gallonage as you lose X amount of gallons for each foot the water is traveling upward and for each bend/fitting in your plumbing.
What type overflow do you have and what size is it? (OFBox, RRtank...)
The ONLY placxe you should reduce the amount of flow from a pump is on the 'out' side by using a gate or ball valve. Never reduce the amount of water going INTO a pump.


Shalon - as George asked, we need more info on the display tank (size) and what type of overflow you have on there to be able to answer your question.

i have a 30 gallon and planning to use a u tube or 1-in pvc as the over flow for the 10 gallon sump

So you plan to have an overflow box..with a U tube in it? Any chance you can have the tank drilled?

no the tanks not drilled trying to avoid drilling it
