    I was beginning to think I knew my way around my Vaillant Turbomax Plus boiler, having recently replaced the pressure release valve and repressurised the expansion vessel. But now it's leaking water and, while I can see where it's dripping, I don't understand the function of the component that's leaking. If you look closely you can see a drip just below the hole in the brass fitting. Look forward to hearing what this bit does, and how (if at all) it can be fixed! Thank you.

    Hmmm it’s a tricky one but I’d advise putting the cover back on, turning off the boiler and calling out a gas safe engineer as you are not qualified to remove the cover as this forms a combustion seal and you are putting you and your family at risk by working illegally on a gas appliance

    I've only folded down the control panel. Not removed the outer casing, let alone the combustion chamber cover. But of course I'll get someone in if necessary.

    However. You have changed the PRV which is a safety control device. Which means you do actually need to put the cover back onto
    The boiler and get it checked over. You probably will not get much more advice here.

    I can’t be bothered differentiating anymore as far as I’m concerned if you ain’t gas safe no tinkering

    Nice easy and common fix shouldn't cost that much either under £200

    Whilst no one can stop you to tinkering with your own boiler the consequences of you creating bigger problems needs to be set out. If you were to produce a Big Bang by accident if might invalidate your own home insurance, hurt your family and neighbours, and open you to a criminal prosecution...police are hot on this now as it’s an easy prosecution. The work you have already carried out is defined as work to a gas appliance and as such must be carried out by a qualified person. Rob Foster aka centralheatking

    I certainly don't want to take any risks, whether safety-related or legal. But obviously the rule isn't simply, 'Don't touch a boiler' as user controls are part of it. Is there an easy link that will tell me what I can and can't do?

    That's helpful; thank you. I'd still like to know what the part is called, so I can tell the engineer and avoid extra costs.
