Stockman

[Munch]

Having issues with a stockman overflow mod on the tank, still noisy. Anyone running this setup by chance?

I'm getting a flush like behavior, it fills up, then woosh, quiet for a bit, then woosh...

Never used it... Can you do a herbie? They are silent!!!! (Even in the sump area) I'd never use anything else again.

 

[Dr.DiSilicate]

Do you have a hole drilled in it? You using a ball valve under the tank to restrict the flow a bit?

 

[Munch]

No room for a herbie. I have two drains and one return. Was running one stockman, and the other as an emergency overflow. It does have an air tube with valve to control airflow.
Are you saying run a valve to slow down the drain? If so I heard this was a bad idea... ????

 

[Munch]

Or so I thought... I thought the Herbies had the t near the top... Turns out that was the Durso. So I have no room for Duros.

Guess I'll give the Herbie a shot!

You might try adjusting the depth of the air tube up and down in the drain pipe. Or try increasing the size of the air tube.

You're getting a siphon in your drain and introducing enough air at the right place will break it and not allow it to form.

Also, since you're using only one drain, make sure it has the capacity to drain what your return pump is pumping.

And, imo, constricting your drain with a valve is a bad idea.

If you have three holes that's all ya need for the herbie! Do it! You'll love it. 1 drain with the ball or gate, 1 emergency, 1 return.

I also recommend the herbie. Definitely spend the extra money and go with a gate valve over a standard ball valve for tuning.

Gate valve is worth the price, about 50% more. Way easy to adjust and fine tune.
