RO System + Misters = Drip Drip Drip

[XtReMaTriX]

I am having a bit of a problem. I just hooked up my misters directly to my RO system and apparently the presure from the tank is making all of my misters drip none stop. From just overnight my bucket which holds around 6 gal filled up from waste water and almost overflowed.

Anything I can do or get to stop the misters drop dripping when the pump isnt on?

All of my misting equipment is from Mist King.

Thanks!

I suggest you contact Mistking, im sure they can help...

You will probably need a normally off solonoid inline after the pump to keep the pressure of the RO unit to keep the nozzles from dripping . Hook it up into your timer or off on switch . I think Marty sells one .

You could always use a sprinkler in line selenoid with reducers to 1/4th from like home depot or lowes. It'll be cheaper and they have timers for them too. Only thing is timers only do 1 minute on off times.




Goodluck,
Nick

I wonder if it would be better to place the solenoid ahead of the pump? That would keep the pressure off the pump head, which should equal longer life. It would be best if the same timer ran the pump and solenoid, ensuring that both would be on and off at the same time.

The other option would be adding a switch to the storage bucket that shuts off the incoming water line when the bucket is full.

I don't know what pump you're using, but if it's the AquaTec 6800 that he's selling now it's absolutely not designed to shut off the flow of water when the pump is off. It's a booster pump, so it "boosts" the incoming pressure of the water line. Notice on the label that it says "maximum inlet and outlet pressure of 125 psi".

If you're feeding it from your pressurized RO tank, there's your problem.

You'd better check the output pressure of the pump when it's working, too. If you're blasting 60psi into it and it's putting out 140psi, it's going to die and the factory warranty will be void

If your tank can supply enough pressure to feed the nozzles (you don't say how many you have), then you really don't need an expensive pump at all. It only takes about 30psi to crack the check valves on these nozzles, so if you can give it 50 or 60, you just need a solenoid to shut it on and off.

RO's typically have a shut off built in that stops the RO from making water after the pressure on the RO side reaches 50% of the incoming line pressure. Most places the water pressure does not exceed 80 PSI tops, and water equipment is rated for a continuous 125 PSI max. My understanding of 6800 pumps is that they boost the pressure to 80 PSI not add 80 PSI to the line pressure (although I am not 100% positive on that.)

AJ, like I said in the email, the RO tanks have usually a pressure of 7psi when properly inflated. This allows the tank to be filled up to the limit by house water pressure (usually anywhere b/w 40-60psi). 7psi will be enough to make the nozzles drip. Your order has already shipped, you should get it in a few days. Place the solenoid b/w the reservoir and the pump, then plug in the pump and solenoid into the same timer.

That's what I have in my dart setup. It's been working for a few years without any issues.

if you have any questions, email me.
