Herbie style overflow

[fkshiu]

Hmm, that's interesting. I've got a 90 and a 45 degree elbow on my Herbie main drain and it has never had any difficulty re-starting. A Herbie is completely gravity-based so it's hard to imagine a situation where one would not re-start as long as water was flowing downwards.

What sized pipe are you using? And how much flow do you have going through the overflow? Perhaps with narrow pipes and low flow the valve could be closed enough such that some slime or gunk creates a blockage???

with the down turned elbow, you doing this style?

I am not doing Beananimal's style. The pipe I am using is 3/4" and the flow is less than 200 gph. So I am not sure why it is not restarting.. unless the air is being trapped too fast? I don't know how to solve this.. and at this point I do not want to redo everything. There is definitely no slime or gunk in it because this is all brand new piping.

Pics coming up.

drill a small hole (1/8") in the top of the elbow inside the oveflow on the main drain. The main problem is that the main drain isn't low enough and enough head pressure isn't building up to push the air out of the elbow.

Oh.. I see... I will give it a try and let you know what happens..

I was thinking of making a trip switch so I would have to physically reset/turn on the return pump in the event of a power outage. However, I would rather not have to resort to something like that.

Btw... that definitely does not look like a herbie style..

It looks alot more like beananimals "style"... at least from what I can see in the pics..
