Having a bit of an issue with some hand pulls and hoping someone could have the answer.
I’m trying to sort some gas assisted hand pulls that are used to pour polypin cider. Although the engines are set for 1/4 pint pour over time they have got worse and now just sputter out the cider.
I’ve switched to inline check valves and it’s done nothing. The gas has been turned off as whenever it’s on, the cider just freeflows out of the tap.
