Beer Pouring Flat

[KennyPowers55]

I have a keezer with a 3 way secondary regulator split to a two way and three way distributor. The third leg on the regulator is not being used.

The last batch I made tasted ok but poured flat, even though the keg seemed to have pressure. I ran out of CO2 at some point and let the beer sit for a week so I figured that was the reason for the flatness.

I brewed a new batch and the same thing appears to be happening. The beer just pours flat. I jacked the pressure up to about 25 PSI (according to the gauge) and it doesn't seem to help. If I hit the PRV on the keg it does let air out so I think the keg is holding pressure. I also get a whine immediately once I open the tap.

When I first put this together I made 10 foot beer lines for all the taps and I could serve at around 11-15 PSI with a nice head.

Any suggestions would be appreciated.

Is this happening with the same keg as the previous misadventure?
If so I would suspect a slow gas leak...

Cheers!

I don't think so. Would a keg leak cause this?

All of my kegs are of the used variety purchased from various advertisers here. I have not been able to pinpoint it down to a single keg yet.

We had a recent thread with a similar start that was resolved to a leaky keg...

Cheers!

I don't think a slow leak would cause either carbonation or serving problems. Both carbonation and serving are driven by pressure. Unless the leak rate is a significant fraction of the max flow rate of CO2 into the keg, there will be no significant pressure loss in the headspace. No pressure loss in the headspace, no flow or carbonation problems due to the leak. Seems a leak fast enough to cause pressure loss would empty a tank pretty quickly. Anyone know what the max flow rate thru a typical CO2 regulator is? That would give some idea of how big a leak might give an observable drop in pressure.

I still don't buy that the problem in the other thread was due to a leak (that doesn't mean there wasn't a leak however.)

So some good news. I had the CO2 set to around 25 since the last time I posted and went to pour one today. It came out fast. Released the keg pressure and dialed the regulator back to around 10. It pours nice and tastes acceptable. So I am happy. For now.
