My JBJ top off with RO water recently starting acting up / seems like the sensor is not working properly.... move it up and down and it kicks in however it still is red after and will not kick in unless I move that sensor / doesnt apear to be any build up on the sencer ... as I am using ro water for top off water....

any ideas what I need to do to make this work again or is this a cronic problem with jbj top off devices?

Doesn't matter if you're using RO or not, you're float is still sitting in salt water. Try soaking it in water and vinegar for a bit, just to be sure it's completely clean. Have you checked the plug for the sensor to make sure it's not loose, I know mine has done that.

I will try cleaning it in vinegar / for now it looks like I may of solved the problem as I noticed the lift pump I am using was a little slow so I blew it out and it is pulling more water now and everything apears to be back to normal... I will clean the sensor just in case ....

Just wondering it that little aqua lifter pump is a little to small / may be the root cause

it aqua lifter is too small, wont work properly with the ATO. the ATO will time out before it pumps enough water.

+1 on what don.ald said above.

I had the same trouble - and it was the aqua-lifter that was the problem. The ATO has a fail-safe feature in it. It prevents the ATO from running on if the sensor gets jammed "up". I think the default setting is like 5 minutes, and can be adjusted up to 10, but its been so long now I don't remember exactly the length the time out is.

Once the time out has kicked in, it won't start up again without being shut off/on.

You can set the time out if you take the cover off.

Once I put a proper pump on the ATO, it has worked slick ever since.

I'm pretty sure I found a manual online which detailed this, but I can't find it or the link now.

But if you put a faster pump on that sucker, I am sure it will work for ya.
