Cheap ATO setup for RODI Reservoir

[Richmond]

Good day! I know this topic has been beaten quite a bit, but I'm looking for a cheap way to auto fill my RODI reservoir.

After the recent R2R sales I've jumped in on, I've stocked my tank with beautiful coral. I'm not more motivated than ever to stick to a rigorous maintenance schedule. As such first thing I'm going to do is make a saltwater station where I can just drag a hose to the tank rather than buckets. I'm doing a reservoir for RODI and need a cheap way to ATO the tank.

My RODI has a built in booster pump and the entire unit shuts down if power is disconnected. As such, any float valve setup would work. I'm just looking for an effective way to do it cheap.

Thanks in advance.

I don't think it will be as easy as you think. You need a way to turn off the power plus stop the water flowing to the reservoir and stop the back pressure to the RO membrane. I thought they used to make a complete kit for this but my quick search didn't find it. I believe these 2 things are what you need.

There may be a much cheaper DIY option. Now I've never done this with a booster pump so my advice may be completely wrong. 20 years ago I did this and had to have the auto shut off kit but I didn't have a booster pump.

If you are going to have the water source always on. I would not go cheap. I would want as many redundancies as possible to avoid flooding my house or tank. Brs has pretty good video on hơ they plumb theirs.

The system has an internal shut off. There is no water pressure on the membranes and no waste water moving thru the system if the power is off. Am I missing something? I have the aquaticlife pro 500 GPD system.

The system is in my garage and drains outside if it does flood. I am going to setup a secondary shut off above the top float in case it fails.

Do you have a link to the system? I can't find anything on their site for what you posted.

The absolute cheapest way would be a float switch rated for the voltage and current of your pump setup so that when the float is low the circuit is closed and the pump turns on. The next simplest option would be a low current rated float switch that switches a DC power source connected to a solid state relay that switches your mains voltage to the pump.

Not really a good approach because the system will short cycle.

Our Hi-Lo Controller will kick the system on when water level hits the low switch, and turn the system off when water reaches the high float. A solenoid valve run off the booster pump circuit will do the same for the flow of water. http://www.buckeyehydro.com/shut-off-latching-solenoid-valve-1-4/

How does it mount from outside the storage tank? Does it go thru the side like a bulkhead?

The float switches can mount from outside the tank - you just push the float through the drilled hole, and hold the float up against the outside of the tank wall and tighten the nut - a tight rubber bushing rolls and seal the float. Or you can mount it from inside the tank as well.
