My Herbie overflow write up. (pics/beware)

That was quick.


Told you.


Don't forget safe.

 

Now I know why two drains are needed.

Originally I had the secondary drain 3" higher than primary... and I was getting frustrated cause water level would rise and Id have to keep playing with gate valve

Then I came back to this thread and re read it. Definitely made more sense after doing the job.

Then I realized second drain some people use it for a small trickle. Thats what Im using it for... and it works flawlessly.

Pleased that I invested a measely $40. to redo my plumbing.

 

I don't use the emergency for regulation but some do. Irun my level an inch below the emergency, and the emergency is just below the overflow level. So at most my water falls in the overflow 1" and does not make noise, and my emergency kicks in before the tank starts to back up.

 

secondary makes it alot eaier to regulate. Cause for me the water level would slowly rise. Id then open valve a tiny bit. Then Id get it to stop rising and then id see it lower....

So I have it set on a tiny rise where the secondary catches the trickle. works well for me.

 

Herbie seems like a great idea good rad guys thanks for the share.....

Hello. Let me ask if I understand this.

1" drain below the waterline, gated, down to the sump.
1" emergency drain above the waterline, unregulated, down to the sump.
Pump the water from the sump, back to the surface, regulated

Water line in tank dropping = increase drain valve, reduce return valve
Water line in tank rising = reduce return valve , increase drain valve
Water line in sump dropping = increase drain valve , reduce return valve
Water line in sump rising = reduce drain valve, increase return valve

Power goes out and 2" of water in tank drains into sump and sump overflow = ????? pray your waterline in sump was low enough to handle the 5 extra gallons of water??
