pumps

[jon1985]

So my fiancee and I just moved into our first house. I am going to have my tank on the second floor but produce all the top off water and water change water in the basement 1 floor below. Fortunatly the ceiling in the basement area I will be making water isnt finished so running some tube wont be hard and the area the tank will be in is right above where the water will be made.

I am currently using 2 55 gallon drums to hold water, both fresh and salt. My plan is to pump the water from the basement, up some tubing then into the tank, and vice versa to remove water into the laundry tub. I want to use tubing because it bends easily so I wont need to remove any drywall to get it into place.

My question is what type of pump do I need?

I dont need a ton of flow, I only change about 20 gallons at a time and it doesnt need to be super fast.

I will include pics as things get going

How much head do you think you'll need to overcome? Going from a basement up a floor might be 20 to 25ft? That will have a direct impact on what pump can do the job.

I have a mag 7 pumping up 10 feet from basement mixing station to 1st floor sump thru 1/2 inch pvc. Works great and flow is adequate, takes 5 minutes for 20 gallons.

Pumping 20 ft or greater you really need a external pump.

I would think it would be less then vertical feet. The house is a high ranch so what I am calling the basement isnt really under ground.

Easy way:

Determine the vertical rise in feet. Compare that to a pump curve and see what the flow rate is. You may want to determine the velocity at the exit so you can find what is lost due to the pipe itself as it will start to come into play at that length of travel.
