planning for a basement sump

I am in the planning stages of setting up a sump in my basement and I have a few questions. My tank is a non drilled 125 that is in my living room. I want to make a 55g sump in the basement below and run the plumbing through the floor. That being said, what size overflow would you recomend and what size pump would I need to return it to the tank. I haven't measured, but I'm guessing the water would need to be pumped back up about 6 feet.

 

How do you get only 6 feet? Is the sump going to be at theceiling level of the basement?

You are probably going be closer to 8 feet, the average ceiling height, and add in another 3 or 4 feet for fittings and head loss in the plumbing.

High head pumps are more expensive to purchase because they are manufactured with tighter tolerances plus they cost much more to operate due to the work them must perform. You best bet would be an external pump such as an Iwaki or PanWorld and a drilled sump.

 

Yeah I was only counting the height from the sump to the ceiling It will probably be closer to 8 to 10 feet when it is all said and done. It sounds like an external pump would be more appropriate at that measurement with what you have said. How do I calculate how big of an overflow to get?

 

You're gonna use a hang on back overflow and run the plumbing thru the floor??

 

U are more than likely going to have to go with an external pump because of heat issues. The size pump ur going to need to run to have good pressure is going to get very hot i'm sure.

Something else to keep in mind... your going to go with a 55 gallon sump, whats your water level going to be in the sump when running normal and will there be enough space to hold all the water when the system isnt running. If u have a power outage then ur going to need room in the sump to hold all the water from the hoses.

IMO a 55 gallon is way to small to use in the type of set-up ur talking about.

 

That was my plan, yes

 

I was under the impression that the sump is usually only about half full and that if the power goes out then the tank will empty until it drains under the the overflow intake. I wasn't thinking about the water in the hoses though...Sounds like I will need to do some calculating.....
