I hate my ATO

I don't dose, just top off with RO. The one and only problem I have is that I need to periodically clean the float switch to insure it has freedom of movement. I use the autotopoff.com ato with a maxi-jet. Works great.

 

Is this just RO or is there kalk water involved?

 

Pump fed ATO? That is my only solution hahaha! I love my Tunze ATO but I didn't like the price at first.

 

If your just dosing RO water what is clogging it up???

 

Well, I am not sure what to tell you. First I need to know brand of ATO you have. I also have no idea what a little valve thingy is but a picture would help.

Either way I would recommend taking the float switch out of your sump and scrubbing it down good. I have gotten a lot of tube worms in mine before that blocked the float from moving up and down.

I would also consider replacing the ice maker tubing...maybe it is clogged from the kalk still.

Also this gravity feed.....I am stretching here but possibly there is not enough pressure to push the water from the 8 gallon to the sump consistently. Yes I know we are talking gravity but sometimes an air bubble in the ice maker tubing is all it takes to fight gravity. As I said I am stretching my ATO is fed straight from my RODI unit so there is pressure all the time.....lots of it.



Also, if you take apart your float valve, make sure you put the float part back in correctly. I put mine in upside down and it topped off when the water level got too high instead of too low.

 

Can you adjust the angle of the float valve? On mine, I can adjust it so the end of the float is the only thing touching the water so that no saltwater touches where the RO/DI comes out. This would help it to stop plugging up.

 

If you used kalk or soda ash at one time, you're probably just dealing with residual build up. I would try taking the float valve off and cleaning it with vinegar or muratic acid...or just replacing the float valve.

Yeah take apart that float valve as much as possible. Soak it overnight. Poke it with some wire, brushes whatever. Replace the white tubing and I would bet you are good to go. If that all fails, a replacement float is very affordable. They are sold at BRS for super cheap.....

I got the exact same setup doing the same thing as you.  Mine has clogged on me a few times in the last month.  The stopper in the valve gets stuck, does not fall down as the float lowers during evaporation.  I blow a little air in there each time I replace the water, seems to help keep it from sticking.
