Float Valve suggestions for ATO?

[Electrobes]

I have a ATO container that it directly above my sump, and would like to use a float valve instead of a powered option.

It will only be RO/DI water, nothing else.

What are the current suggestions for the most reliable float valve to accomplish this?

Thanks!

I have done this recently. The problem I had was finding a way to drill the ato container and have the 1/4" ro line come out of it because they dont make bulkheads that small.

Anyway, I ended up getting this one

and I used this with silicone since they didnt have a waterproof o ring to come with it.

hopefully the name doesnt get shut out.
