I would like to install my RO/DI unit beneath my kitchen sink to feed a faucet for drinking water (and my refrigerator water and ice maker) while at the same time feed a reservoir in my crawlspace about 30-40 away (directly beneath my new 75 gal tank with sump).
My thought is to install a 5 gal bladder tank (in the crawlspace) beneath the kitchen sink and split it off to a faucet and to the refrigerator using 3/8 OD hose.
I would also like to feed the reservoir (with a float valve) with the same 3/8 OD hose.
Im thinking that using 3/8 OD hose will be good for running a good deal of volume to the faucet and also for effectively running a line approx 35 away to the reservoir in the crawlspace.
My thought
is to feed a float valve in my sump from the underlying reservoir using an extra booster pump I have lying around and a pressure switch that came with it. Basically when the float valve drops then the booster pump will kick on to replenish this evaporation in the sump.
Heres the basic plan:
