Can anyone advise...I have a britony combi boiler and the air vent is leaking quite badly. My plumber came to fix this on Wednesday however it' now dripping badly again. He can't come out until the end of next week now. Is there anything I can do in the meantime to stop the leak? Can I close the plastic screw at the top?

If the water is coming out of the very top ,where the black cap screws on, then yes screw it down .should be OK for a week till plumber gets back to sort it.
