How to stop waste water with booster pump

[pookie]

Question is in the title... my rodi unit is running water through the waste line after the container is full... the booster pump turns off but the waste line doesn't... what do I need to stop this from happening as I'm tired of turning the water source off manually pics below on setup.

From the picture it appears that you don't have the auto shut-off valve installed. That's the one with the four fittings.

So yes I dont because when I bought the auto stop for the pump it said to take it off as it MIGHT interfere with it. Later on I installed it again but could never get the pump to turn off but the water stopped flowing through. So I just reverted it and I was tired of messing with it. Is there a certain place to put the tubing? I looked it up online and was having problems still.

It should go together like this. The booster goes on the feed line, which I imagine that is how you have it.

I will test it when I get home and update if it works or not! Thanks

Swear I did the same exact same thing last time but this time it worked! Thanks so much!!!

You're welcome.

Good luck with your tank.

When you install a booster pump and pressure switch, the best configuration is to remove the 4-ported hydraulic auto shut off valve, and instead use a solenoid valve installed on the feedwater tube. This solenoid valve should run off the same 24 VAC that powers to pump and is controlled by the pressure switch.

Suggest you use a quality solenoid valve n this application, rather than the most inexpensive solenoid you can find. He're's what we typically recommend:

Here's a schematic of how you best hook everything up. The dashed red lines are wires, and the blue lines are tubing. Looks like you have your booster pump before your prefilters.

So yeah, to no shock the switch for the pump won't turn off again before the auto shut off even with the 60 psi switch so... that's a bummer. On the other hand I've never even heard of a solenoid. Do I need to get the wire harness that is optional? Do I need to "program" it. Is there a good video that explains for this situation. Any advice would be fantastic as I'm getting annoyed with the pump just running and me having to unplug it...

A "solenoid valve" is nothing but an electrically powered valve. It either opens completely or closes completely when you give it power. Small, very common and simple device. No programming. I would get the wire harness, yes. The only thing to remember with solenoid valves is that they are uni-directional - meaning they have an IN port and an OUT port, and you must install them so water flow in the correct direction. Regardless of the solenoid valve, one or both of the ports will be labeled, or there will be an arrow indicating the correct direction of flow.

So just to clarify, i should connect the booster pump after the 3rd stage or second stage? Then the solenoid should be before the 1st stage? Also i still need the pump switch that i have but not the auto shut off (the 4 connector box)? Sorry I'm very dumb when it comes to anything plumbing! Thanks

Let's start with a definition. The word prefilter refers to any filter that touches the tap water before that water reaches the RO membrane. So in a typical RODI used in this hobby that would mean at least one sediment filter and at least one carbon block. So as shown in the schematic I posted above, we recommend you install a strainer after your prefilters, and then install your pump downstream of the strainer.

Yes - the solenoid valve would go before the entire system. When it shuts, everything downstream gets no water.

It is best to use a pressure switch to control the electrical circuit, and remove the 4-ported hydraulic auto shut off valve from the system.
