RO/DI (DUMB question)

[skeety]

Okay...this is a really dumb question...and considering that I've already installed it, the timing is even WORSE!

How do I shut off my RO/DI unit?

Meaning...if I have it dripping into a 50 Gallon bucket...and it puts out 60 gallons per day....what happens when the bucket's full? How does it shut off?

[mwanttie]

There should be either an auto shut off valve that would also require some sort of shut off valve at the end of the discharge tube (good water) or there should be a manual shut off valve on the front of the unit. It is normally on the tube after the prefilters but before the RO filter.

or you could get a bigger bucket


Sorry Skeety, had to.

I think the best thing to ask would be how did you install it? and what kind is it?

[skeety]

I got a Ken Delux Maxima 60GPD

Off of my main water pipe coming into the house, there was a T. The output was plugged. I bought a fitting that screwed in, and has a 1/4" tube hookup on the end. Plugged the input (to the RO/DI) into that.

Then took the waste water line and ran it into my sewer line.

Got a 50 gallon (rubber) garbage can from Home Depot, drilled a hole about 2" from the rim, and then took the output (from the RO/DI), and stuck it in that hole.

But I can't find an off swithc/valve anywhere.

Might have to install one.

Anyone else have this unit, and know where (if there is one) the off switch is?

When the buckets full it will spill onto the ground or floor.


You can either buy a float shut-off or DIY one.

From extensive study I can unequivocaly state that when your 60gpd RO/DI unit runs into a 50 gallon bucket for 24 hours, it will overflow. I did not one but several studies to verify this and it did it every time. Not only that but if you'd used a 100gpd unit like I did, it will overflow even faster and particularly if the container is inside, with more dramatic results. Only when I also tested an "RO/DI Shutoff Valve Kit" did my results vary.

I had to complain to my RO/DI resin manufacturer that I only got 50 gallons out of the cartridges. Of course, he asked the key question about how many gallons went on the floor. He claimed the water running on the floor voided my resin warranty.

The key to your problem lies here: How did you keep from getting drenched when you replaced the plug with the fitting?

Same here yardboy

I forgot to turn mine off one night, it ran from 10pm to 4am, It's a 75 GPD running into a 5 gallon bucket...
I bought a shutoff kit the next day.

The on/off switch will be on the water input line for the RO (between the tee and the unit).

[yardboy]

Heck I can even demonstrate a method of wasting resin when you have the shutoff kit! I did a water change and decided to go ahead and make up some new saltwater. Walked off and forgot it somehow so the fresh ran into the salt, which overflowed, diluting the salt to nothing, running the RO/DI all night and the next day, completely exhausting a new DI cartridge! I suppose a fool can't design a foolproof system! Smartest thing I did was put the whole system outside so it ran on the ground. I'd have probably killed the grass and shrubs around where the salt went except we had a hellacious thunderstorm the next day that dumped 8" (yes, 8") of rain in about 4 hours. Mama Nature must have been looking out for me.

The unit itself doesn't have one, easiest thing will be to get a ball switch from home despot or whatever to go between that T and the screw in fitting that takes the 1/4 inch tubing

Mine is just screwed into the laundry tub sing so I can turn the water on and off with the faucet

Oh and in the event you overfill the bucket a shopvac does a reasonable job of sucking up water OR better yet if there is a steam cleaner vaccumn in the house., the hose attachemnt on those is a klutzy person's salvation

HAHAHAHA...I can seriously not thank you enough. Only one problem...while I normally don't mind rolling on the floor with laughter...it SUCKS when the floors covered in water!

While I did get a 60gpd unit...I really never forsee using that much, so if I could *train* the unit to just keep my 50gl bucket full, I will be happy.

And to answer you final question...I shut off the Main water pipe coming into the house...then installed everything, then turned it back on.

It's working GREAT! Just wish I could get it to STOP working for a bit.

Sounds like the route I shall take. Thanks!!!
