Spike Flex holding less pressure every time. How can I fix?

[Franktalk]

I have two Spike Flex + fermenters. At first, they both held exactly 15 psi as advertised. Now one and two years in they only hold 12 and 13 psi respectively. I liked to ferment at 15 psi because not only did it ferment excellently clean lagers, they were almost completely carbonated at the end.

My question is: how do I get them back to 15 psi? Will a new belt do it? is it the All in One PRV?

Have you tried ‘burping’ your gauges? Just pull out the black rubber plug and it can often make them read accurately again.

No, but I'll try it. Thanks!

Hey, I tried it and guess what? It worked. Thank you, waynorth!
