CO2 regulator question

[seanppp]

An hour ago I accidentally broke my shut off check/ball valve (https://www.morebeer.com/products/shut-checkball-valve.html?site_id=7) and so I just put the hose to the regulator directly. I did my usual 30psi and shake, then turned it down to 7psi. When I put the pressure down, CO2 came out of the regulator (couldn't quite tell where, maybe the knob itself). I am wondering if this is normal when there is no check valve to keep the 30psi on the other side or if I have a defective regulator.

Does the regulator normally relieve pressure when the setting is lower than what is in the line downstream?

Thanks!

You may just have a looser connection to the broken piece that is allowing the back-pressure to escape. A regulator usually will only pop it's relief valve when it's overpressurized to avoid internal damage.

I took the broken piece out of the chain. It's just the hose into the regulator. I think it was the regulator that was relieving the pressure, not sure why though.

This is normal. It is likely that your regulator is self-relieving on the low pressure side, as most beverage regulators are. In other words, they are designed to vent excess low-side pressure when the low-side pressure setting is reduced. If you look closely, you will likely see a hole in the regulator body from which the excess pressure escapes.

Excellent! Thanks for the info. Good to hear it's not broken. Now I just gotta replace the check valve so I don't relieve (ie lose!) any more gas.

Thanks!

More importantly, you don't want to get beer blowback into your regulator, if for some reason the gas tube is below the liquid level.
