Auto Top Off styles??

I would say ATO sensors screw up just as often as float valves. When is the last time your toilet tank violently overflowed? Even at city pressure 24/7.

The timer is the safety factor that keeps it from being a constant supply of pressurized water, and the timer is tuneable to meet your specific ATO needs, down to the minute if you wish.

I don't think twice about mine, even on 3 week vacations. A 100 GPD RO/DI can only make about 250ml of water per minute. If someone hasn't noticed that a sump or barrel is slowly filling over several days, eventually you will experience a spill of a few litres at most. Not really a big deal or risk IMO.

I like my solenoid system dual nc valves and the boost pump hooked up to a wall type count down timer. Total shutdown every time with a very slim chance of failure. Not to mention I have a timer set for the same time that the system is running and I religiously check to make sure that the system is secure before I go to bed its to the point that I can't sleep enless I've checked. Even calling when I'm staying somewhere else for the night.

Is this using RO/DI? If so, what fills your storage container?

i have ro/di lines ran throughout the house so i don't need to bring out any hoses to do a top off i just open the valve to the tank i want to fill (lines are secured to the sump) and hit the timer to activate the timer on the ro system than i set a backup timer on my phone that is always on me so no matter where i am i get a reminder. each tank ive got the times down to a science as i always top off at the same mark. when i fill a mix tank up again i know how long it takes to fill and the timer even at its longest time setting wont flood it also the mix tanks are in the unfinished utility room that's equipped with a floor drain. we installed this system after flooding 1/3rds of the house . i typically dont have a storage container of strait ro/di. your system sounds rather similar to my setup just a top off has be manually started but will automatically stop after the desired amount has been dispensed.

My RO/Di is a floor away from my sump :-(

That's essentially what I do, very low risk, easy to use, and not many parts.

To cause a flood the solenoid would need to fail on AND the float valve would need to fail at the same time. That would still only cause a 15 minute fail, the timer would need to fail as well to lengthen that.

Cycling my RO system just means a few extra automatic membrane rises per day.

Yup, same here. I have a double manual float system in one sump and a double electronic float (from autotopoff.com) in the other, both feeding directly from my RO/DI output. I have solenoids which turn on every 6 hours for 10 minutes. And the failure mode for the solenoids is in the off position.

Very simple and reliable system. And my RODI has an auto shut-off valve, so no problem with the membrane.

I have an ATO tank that holds 14 g - to fill it I do need to carry 5g buckets water upstairs every Thursday evening. I would love to have a more automated system but like others I have the challenge of the tank being on one floor and the RO/DI in the basement. I have looked at simple ways to run a line from the basement to upstairs, but there is no easy way. Also like others I am afraid that a drilled hole in the floor might result in my premature funeral . Having said this, I have found a way to automate my system somewhat - a 15 year old son who can carry the buckets of water upstairs! Sometimes this system is tough to get started, but it sure beats me carrying the buckets upstairs!

That trick only Lasts so long. Dad grabbed the valves from work I have the on the inlet side of the ro/do system so the copper valve body isn't a problem. He did find some at princess auto ( copper body). I know they make a all plastic one as well as stainless but their expensive ill see if dad remembers who makes them and the supply house to get them from. The timer I'm using I got from Home Depot. For those that their tank is on a different floor if you have a furnace vent close you could snake it up that way or have a length of hose off your ro that you pull out when you need to top up the resivior I used to do that before we renoed the house.

I run a jbj ATo with a maxijet 1200

The maxijet is in a 55g drum in my garage that's fed directly from my rodi system, pumped through a hose that goes from my garage to my living room
