Under pressure

Finished early today to get back and go out for a run. Needed to get the camper ready for a weekend of dog swimming in Sheffield. Bought a new regulator to pump up the beer kegs so had a go tonight. Its meant to be used with a Soda Stream bottle but when I put it on the over pressure valve kept blowing. Not sure if it’s a faulty reg or if the bottle is too higher pressure. Will have to sort it out on Monday.
