Herbie Help

[duncangweller]

Hi All,

I'm having a bit of trouble with my Herbie setup.

This is the third tank in which I have run a Herbie and the only one I have had any problems with.

In the past I have been able to tune the overflow gate valve very easily and it would maintain a constant water level for months or until I flushed the valve.

It's only on my current tank (which has been setup for 6 months now) that I have problems.

It seems that, many times a day the level in my overflow drops or raises. It is starting to get really annoying as I am constantly fiddling with the gate valve trying to get it right. Sometimes even 5/6 times a day.

The other annoying thing is that when the level drops in the overflow it splashes water up the wall and that equals an unhappy lady friend. So you can appreciate my desire to get it sorted.

The main overflow pipe is approximately 5" below the surface with the emergency being a cm below the top of the teeth in the overflow.

I tune the Herbie with a gate valve.

If anyone has any advice in what may be going wrong I would greatly appreciate it.

Much obliged,
Dunc
