I have a RO unit that puts out roughly 20gpd. worked just fine filling up a bucket right at the source,but now I have my sump done and all plumed and I put in a float switch and ran tubing under the house from the tank to the kitchen(where the ro unit is 30ft away) I'm guessing the its too far of a distance to travel, because nothing with come out the other end. any hints or tips??

Hi,

How long did you wait?
It may take a while for the tubing to fill up before you see anything at the other end. If you have enough pressure in your water source for the water to pass thru the filter, once it's past the filter, it has to go somewhere.
One solution could be to relocate the filter higher. Gravity may help put the RO water where you need it.

My 2 cents.

same problem here, My RO/DI is in the basement and there is not enough pressure post DI to get it up the "hill". They do make pumps for the units, but I have not shelled out the dough for one yet. My only other option is to put the RO/DI unit upstairs somewhere, and there is no room, nor anywhere I would want to put another potential leak.

Probably around 150.00 you can get a nice pump designed for it.

I think the pump is to boost the pressure going into it ,not sure it would come out much harder

oops......In looking at them, I thought it was for the outbound pressure....glad I did not order one

Thanks Casey

hey randy, have your float valve on a reservoir at/under the filter, run the finished ro/di water into this reservoir so that the float valve will cut off the ro filter when the reservoir is full. Place an inexpensive pump in the bottom of the reservoir. Place a pipe on the pump running to the sump, and fix it so that it will empty into a fixed tube that is higher than the sump and the top of the ro reservoir. Place an electrical float switch in the sump, and run it to the reservoir aera, where you will plug the pump you've placed there into the control relay. When the float switch drops low enough, the power will come on for the pump, pumping water into the sump until it rises enough to cut the power for the pump. Make sure that the end of the pipe is higher than both the sump and the reservoir, or make a siphon break in the supply line at the sump end. This will prevent the pipe from continuing to siphon once the power is cut to the pump.

Ok I have left in on for 3 days now and I think only a couple drops have come out

the Ro unit is in the only location that I have room for and is about one foot total higher than the sump.

The resivour idea sounds good but I have no room at all for anything else near my tank nor do I have the cash for a electric float switch.

I know I have realy crappy water presure thats probablythe reason it wont got to the sump huh?

thanks

What is your pressure ? Do you know?

 

[cwby416]

I have no Idea

Go with tdwyatt's idea or go to home depot and pick up a drinking water add on kit with a pressurized reservoir. You can put that in-line at a point where the water will flow into it. It should provide sufficient pressure to make it to the sump. I assume the float valve is on the sump side? I recommend you put some d-e-e-e-e-p thought into your setup. Many a time my auto-top off gave me wet feet in the morning. It took me a while to get the kinks worked out. And with out spending more money than you want to, you’ll find there’s always something that could go wrong.

The weakest link in my current system it the mechanical float valve. Not because it fails, but some times I get in a rush and don’t put the lid back on right on my reservoir. User error. Just goes to show there’s always something.
