    Hi
    Worcester Greenstar 30i Combi ErP
    Just had some plumbing done with a new shower and bathroom. the condenser pipe was rerouted and since I can hear the sound of trickling water inside the boiler when the heating is on.
    temporarily I had it running into a bucket while work carried out. No noise apart when it discharged.
    The pipe shown runs to a soil pipe.
    Any ideas?
    No loss of water anywhere

    I'm pretty sure that boiler has an internal trap for the condensate. You show it flowing into a trapped drain, so two traps. This means that air can't get back into the boiler's trap. Try removing the rubber "bung" at the top of the pictured trap and see if that makes a difference. If it does, then provided the drain pipe runs straight into a drain with an air gap, remove the trap in yor picture and connect directly.

    will do - where would I find out about the internal trap?
    the pipe is running into the soil pipe
    before that, I had it running temporarily without trap etc and into a bucket - worked fine, so you might be onto something
    Thanks

    Check the installation instructions for your boiler. Available on-line if you don't have a hard copy.

    Ok. Loosened the seal as you said et voila. Water running out of the boiler down the pipe. Noise gone.
    You beauty.
    Thanks so much
