Herbie drain is a pain

It then also gets exacerbated because the ATO keeps topping off before it actually should be.

If you have a DC pump then that's the problem.Some of them don't keep a constant voltage which result's in more or less flow(happens to me with jebao12000)What i did is i tuned the gate valve that is just flowing a tiny bit in the emergency drain and when start to push more water it goes down on the emergency,usually doesn't last for long and go back in level.
