Do co2 solenoids normaly let some co2 throught?

[Daveb82]

I just started running co2 and I have it at close to 2 bps. When it is shut of at night it is still letting co2 throught but at around 1 bubble per 7 seconds. Is this normal? And can it cause any problems? Ot should I take it back for exchange? It is a Milwaukee MA957

How long does it last? Mine did that for a few minutes, but stopped after that until it came on. If it's all the time, then I'd look at getting it replaced.

I just checked it's been off two hours and now doing a bubble every 50 seconds

That's not normal IME. Literally, mine would do maybe 4 or 5 bubbles, then none until it kicked on again. One thing you might check... not sure if this is even possible.... but you could unplug it and see if the timer might be somehow providing enough juice to keep it barely open? Like I said, I'm not familiar with the inner workings of a solenoid, but it's just a thought.
