Lifting RO/DI water 20ft/5m

[bondolo]

I am strongly thinking of moving my RO/DI filter and water storage out of my office and fish room to the crawl space (actually it's an "almost standing" space) of my house. A big motivation in this is to use the waste water for watering the garden rather than sending it down the drain and also to reduce the clutter in my office.

I am stuck though on how to get the water from the unpressurized storage tank up to my office. There is a conduit I can use to run a 1/4" supply line up from the crawl space. It will have to go up two stories and about 20 meters total travel. I can't run a large 100gph pump because I can't use anything larger than the 1/4" supply line. For this much head height at the small 1/4" tubing size I don't believe that a regular pump will work anyway. I could use a peristaltic pump if I was only going to do ATO but I also need to do water changes and the duty cycle on peristaltic pumps I have looked at would require days to fill my water change brute container without burning out the pump.

Ideas?

Pretty sure the booster pumps would fill the fill. Ask BRS, or Spectrapure or your favorite dealer

EDIT:

Spectrapure has a delivery pump:

I'm not sure a booster pump will do anything, I thought they worked by basically using existing line pressure and simply exchanging volume for pressure. Although I'll admit I never tried just putting the input side into a bucket of water to see what it'd do

That said the delivery pump is a good option, if you can fish a 1/4" line, hopefully you could get a 1/2" line up there too, although you'll have less issues if you need to restrict your 1/2" line to 1/4"

Although (and I'm sorry if Spectrapure is a sponsor) but those prices are almost double compared to elsewhere.

Booster pumps should work, but have very low flow rates.
You might want to consider a high pressure diaphragm pump.
While the pump fittings are larger, it should be fine on 3/8 or maybe 1/4 line.
Me : I would buy cheap 1/2 inch drip hose.

An Aquatec delivery pump looks like it will work though I am still unsure which model to get. Aquatec has the lousiest data sheets!

I am going to have to see if I can move to a 3/8" line. The conduit I will be using is a 1" conduit that already contains an RJ-6 coax line and two CAT6 and a low speed serial line (used in days long past for an antenna rotator). I was going to remove the low speed serial to add the water line.

Note that there are solutions for the small tube problem.
A quick look shows that you can get 1 GPM in a 1/4 pipe at about 40 PSI.
So it might be better to TEE off some water first.
Meaning, run 3/8 or 1/2 pipe at the pump, with a tee, then a valve.
Some of the water goes back to the RODI reservoir, and some up the 1/4 line to your tank.
The valve on the line back to reservoir adjusts how much.
Hope that makes sense.

Perhaps you want this one?

Thinking more, that is overkill.
With flow rates for 1/4 tube in that range, seems you are better off with a standard booster pump, not delivery pump.
I think most of those booster pumps are in the 0.25 GPM. Not sure though. Hard to find specs.
Which is just about perfect for that tube.

Sorry, you're talking about a different booster. These are powered booster pumps. There are ones that work on pressure, but my link did not contain any of those. I've use a half dozen of them, have 4 running at our facility.
