Hi,
Hope someone can help. I recently moved to a house with a combi boiler heating system. The boiler is a Worcester 350, and I have regularly been keeping the pressure topped up to between 1 - 1.5 bar. But today the pressure is on 0 and every time I top it up to 1 - 1.5 bar, its drops to 0 within minutes meaning I have no heating or hot water. I've looked around for leaks and can't see anything. Should I get out an engineer or can I fix it myself. Any suggestions would be appreciated. Cheers.

Check pressure relief valve, is it leaking outside ?.

yes it's leaking from the outside.
Thanks for the reply

Renew or have it renewed by a competent person.

You could, to see if there's a temporary cure. Turn the PRV head so it opens and snaps shut, sometimes if it reseats itself it may slow the leak or stop for now - you may get some heating until it's replaced.

Yes that seems to have done the trick, the pressure is not dropping as much as before, so I do have some heating and hot water. Going to get someone to fix it as I'm not too clever at plumbing.
Thanks for the advice.
