Barrel pressure

[skinfull]

I use the king kegs and i dont seem to have a lot of trouble with them until recently. Did a flowers original on the 5th of feb, 1st time i have used water treatment 2tsp gypsum & 1tsp citric acid to a 23litre batch, 1st i had poor attenuation, Used 50gms of golden syrup for the secondry been tonight to try the first pint and there is absoluteley no pressure in the barrel whatsoever other than changing the seals on the cap anybody on the forum got any other ideas what it might be.

Hi daab. I used saf 04 on this batch, But did not seem to have much luck with this brew from day one the yeast did not seem so volitile has it normaly does with this strain seemed a bit docile.
Can change the seals but not keen to try and add any more sugar otherwise it will make it too sweet.Any suggestions.
