Red sea ato leaking

[Notsolostfish]

For the people who have red sea ato plus. That part of the check valve leaking that hole any idea why is that hole there

It’s the siphon breaker. Water is supposed to leak out of there when the pump is running. It states so in the instructions.

I also did not read the instructions carefully which resulted in RODI water getting all over my floor the first day of operation.

As stated above by @sublime275 the siphon break will leak water while the ATO motor is running. This prevents water from the display tank from siphoning back into the reservoir. Below is a picture of how I have the connector positioned in my ATO reservoir (ie, any water that drips from the siphon break goes back into the reservoir):

Just changed my reservoir to a mhux higher one almost 1m high. When the ato turns on and then goes back off it keeps dripping. Any idea why? Didnt have this when I had my smaller reservoir
