Herbie Overflow

Thanks you everyone for the shots so far. This is what I thought it would look like but better to ask now rather than get it wrong and have to fix.

I think I've got mine set up fine, but is there a way to Set-it-and-forget-it? I keep having to fiddle with the ball valve to keep the level up or down in my sump. The return end of the sump is about 12gal, but the levels fluctuate as much as 4-5" during the day.

Does the display stay constant?

Easier to tune btw with a gate valve.

They do tend to be fiddly...and I agree with whomever said that gate valves work better. Ball valves are better used for on/off applications. I frequently walk by and give one of the herbie gate valves a 1/32 or less rotation turn.

However...Are you saying that your sump is fluctuating 4-5" during the day? If that is the case, where do you think that 4"-5" of water is going? That would likely mess up your evaporative replacement system.

Would it be best to install your gate valve at the lowest point you can? (lowest practical point) ... More pressure/volume up to the valve ??

The gate valve placement doesnt matter. The gate is used to limit the flow out of the display to the point that the water level inside the overflow box is high enough not to make any noise falling but low enough not to go down the emergency drain.

Yeah...therein lies my mistake...I didn't figure out the height thing properly...now the plumbing is "permanent" at least until I decide to empty the tank to fix it. I don't get much noise...less than my regular overflow...but still not completely silent because of my calculation error.

OK, so my problem is the ball-valve - I'll change it to a gate valve. Do they make 1.5" gate valves?
The fluctuation in my sump happens because the ball valve is either closed too much or open too much, and the pump either pumps out faster than it gets to the sump, or the sump fills faster than it can pump out.

Replace the ball valve with a gate. If you are seeing that much fluctuation I am assuming that it is due to the rising and falling level in the overflow caused by the inaccurate adjustment of the ball valve. Either that or you are having some serious evaporation happening. Gate valves are minutely adjustable and allow for the fine tuning required to maintain the proper water level in the overflow.
