Sometimes my ato keeps dripping, sometimes it doesn’t.

Pump is below the tubing line in the sump. Tubing goes up, then declines to the right side into the sump

If the exit of the ATO line is lower than the water level in the ATO container, you'll create a siphon. I'm guessing that's why it's dripping.

Yeah it seems like that’s the problem, thanks. I raised the line a little bit. Will keep the water level lower in the bottle now

you can also drill a little hole at the very top of the line in your ato res,
that will create a siphon break

Nice. Yeah I didn’t think of that, similar to how I drilled one into my return nozzle. Thanks
