Brew barrel leaked question

[troutie]

A mate has brewed a kit up and got it in the plastic keg with its load of sugar
everything went good until he tried it today and it had no pressure or fizz
but tasted good
it seems his lid let all the the gas out can this be saved and re gassed with another shot of sugar
or any other way

Does it have a gas valve on the lid or is it just a standard lid?
If the lid has leaked your best bet would be to remove it check the washer inside the lid to make sure it's seated correctly then smear a little bit of Vaseline on the washer. If you have the gas valve type lid then just do the lid up again taking care not to over tighten it and add a shot of gas, if you've only got the normal lid then you could try repriming it with 80grams of sugar and then keep it somewhere warm for 7 days to build up the pressure again then move somewhere cooler again
