    The flue pipe for my Valiant boiler isn't entirely airtight and is dripping from the joints. A few droplets dripping now and then wouldn't be a massive problem had it not been for the fact that they contain some kind of sulphur or rust and which stains the grout in my bathroom.

    All help would be appreciated.

    As always, my images appear upside down in this forum. No idea why.... well, I hope you can still work out my problem...

    It is dangerous. And a crap installation.

    Turn it off immediately and get a professional in ASAP.

    Doubt it will be cheap though. New flue, new boxing with hatches.

    either silicone the joints externally (may look rough)

    or get a gas installer to take it apart and silicone it.

    Thanks guys.

    First answer; why would it be so dangerous? It's just the steam from the boiler going trough the pipe. A miniscule amount of that steam again dripping out.

    Second answer; would I use silicone on the outside? Or do I have to take it apart, then silicone the relevant parts and then screw it back together while the silicone is still wet? Seems like I would risk creating a massive mess.

    Actually, I was hoping there was some kind of tape, rubber seal or similar material I could use.

    The flue is not adequately supported.

    The flue is not protected from environment it is not designed to be in.

    It is leaking liquid. If it is leaking liquid, it is also going to be leaking products of combustion.



    Turn it off and get a professional to look at it ASAP.

    "JUST STEAM" is products of combustion or, more commonly, fumes - they can kill!

    If the steam is coming out you have serious problems, as said earlier, don't use it until it's been sorted.

    There does't appear to be any support on the flue either.

    hi , i am a gas fitter for a large company and work on about 4 to 8 boilers a day , firstly what a terrible place 4 a flue , i have come across flues like this before in bathrooms and checked with gas safe and is legal which is amazing just hope the boiler casing never gets a live wire touching it from inside or outside the boiler thus making the flue live while u have a shower , secondly if i come across a flue leaking as yours is i will turn off the boiler and hand out a id certificate & cap the gas to the boiler , i think it may be possible that the rust marks may be condensation on the flue near the shower making the flue rust but looks more like the flue leaking - the flue seal going or gone or not right from the install within the flue , do not mastic , ask a gas engineer to check it out , you do not mastic leaking flues that is terrible advice , tony

    Smeghead is right.... Products of combustion leaking into the property is Immediately dangerous and globbing loads of silicone about is not an adequate repair.

    Smeg head, if the boiler is earthed and correctly bonded then it will be safe even if there is a dead short to the boiler casing... That is the purpose of the earth wire..
