In-line UP reactor setup

[Reuben]

Hi
Just wondering if a need to put a check valve in the co2 tubing between the reg/solenoid (coming off a 2Kg FE) and the up reactor? Seems a bad idea as Co2 might leak? But will water run back into the solenoid? What do others do? I'm not planning on putting a bubble counter before the reactor as I think the bubbles will be to fast to count anyway and I'd prefer to keep thinks simple.

Thanks

Yes, you should have a check valve between the solenoid and the up reactor. It might leak if installed incorrectly but that's easy to check with soapy water. Water will run back, might not damage the solenoid but why take the risk?

Okay thanks for that. I'll pop one in then.
