Topoff pump in basement

[ej797]

Hey,

What pump would you guys recommend using to pump topoff from a basement? I know alot of you have your fish rooms in your basement. How do you guys do it?

Thanks,
EJ

is the tank in the basement? or just the pump and top off water resevoir. when selecting a top off pump you have to keep in mind that it will constantly be turning on and off. this wears out pumps pretty quick so you want something cheap and reliable. Maxijets work great, I've also use aqualifters with great success. if you want to pump water all the way up from your basement, you wil need something bigger.

It's really not a basement. I am pumping from a reservoir on the first floor to my Frag Tank on the second floor.

[george1098]

yea either way, you have to pump it up a whole level, and that's pretty hight for any pump. I have my RO/DI unit in my basement and it feeds a reservoir (5 gallon bucket) in my tank stand. is it possible to move the reservoir to the same level as the tank? that would make life much easier as far as head pressure is concerned.

[ej797]

I really have no choice. I need to pump it to the second story from the first.

I just use an aqualifter. I believe they are rated to 25' head. Not lightning quick, but reliable. I think you would find that anything that can pump that height, is complete overkill for the application.

[george1098]

If an aqualifter works it would be great. I've heard they can move water pretty high too, but i've never tried it.

Aqualifter wont go anywhere near 25'. More like 2.5' I use two of them back to back to go ~ 5'.

[ej797]

Someone has to have an idea of what pump will do this at a reasonable cost.

[sjm817]

So, you need to go...how high from the bottom of the reservoir to the top of the frag tank?

[ej797]

I'd say about 10' maybe less

Too bad you cant move the resivoir to the THIRD floor ( attic maybe), and use gravity with a float valve to come back down to the second.

The RO/DI already has the pressure to pump up hill. It would be a shame to waste that potential energy then have to buy a pump after all.

A peristaltic pump would be your best bet. They can have ridiculous head heights.

you could always try a bellows pump from gorman rupp off ebay. always check if it ran any other chemicals in it first.

plus it will always hold water in the line with out letting it fall back to the water storage.

Those look like some tough top off pumps. Are they safe to use?

LMK,

I push water 10 feet vertically and another 32 feet horizontally with a Mag7 for my ATO. It flows from the basement holding tank to the upstairs. The water flows out very slowly which is great. The downside is that I eat Mag7's about every 4 to 5 months. Going to upgrade to something bigger soon, the warranty folks are on to me :)

Try a reef-filler pump, it is a diaphragm pump, they can handle 100+ head pressure and come in different sizes to accomodate evap rates. you set them to how many gallons per day that you evap and thats about it. nice and convenient. I have a 6 gpd and set it at 1/2 or 3gpd and it pulls from my basement 12' head with 15ft horizontal. Randy Holmes Farley also uses one(got the idea from him on a thread he posted on). They are available at championlighting. Hope this helps!

Similar to what hypernesia is thinking, I would go with a pressure pump commonly used in CO2 soda machines, that usually have quite long runs in restaraunts.

I have 2 Flojet brand pumps, 2125 series, 504 model(outdated). They handle 45PSI each

Other models may fit your need a bit better, I just found these 2 available on Ebay for very cheap as a package deal.

[hypernesia]

So with the flojets you need to purchase a ball valve to control flow and something to run the dc motor on a/c? Sorry if that sounds dumb but I don't know much about electrical. Looks like I might have overpaid for the reef-filler but for what they are going on ebay for I could buy a backup and the wife wouldn't cringe.

[hypernesia]

Nevermind I found the one you linked to and it is already electrical and has a flow control valve. Now I really paid too much!!!:)

Someone is selling a Chemtec Pulsafeeder in the used forum right now for $100. Great pump. I use one from my garage to the 2nd floor and love it. Not very quiet but does the job.
