    Hello everyone,

    I’ve moved into a house a Vaillant ecoTEC plus 624 boiler system in the garage.

    Twice recently I have encountered a puddle on the floor under the boiler. On close inspection I think it seems to be that the white plastic condensate pipe had become detached from the bottom of the boiler at the back on the right hand side (I only came to that conclusion by looking at a diagram in the manual). I’ve followed the pipe into the house where it seems to join the sink waste.

    I’ve managed to push it back into position but would like to know if the loss of fluid is normal please?

    Also as it has now come off twice, is there a way of fixing it so that it stays put?

    Thank you.

    Dotty

    Hi Dotty,
    Yes, fluid from condensate is normal.
    I had an Ecomax where the condensate drain degraded and fell apart, the fluid then delete egraded the internal components until I decided to replace it.

    My advice would be to just buy a new condensate trap and fit accordingly. It will save you a massive headache in the future.

    Thank you but the fluid is not coming from the condensate trap as far as I can tell, I don't know anything about boilers, I'm just trying to work out what is going on. I would not feel confident in fitting a new trap and would probably have to call an gas qualified person.

    The pipe needs clipping is all.

    If you are unsure, I would just use a gas safe engineer to look at it.

    The liquid will be coming from one (or quite possibly more than one) of these places

    1. Cold water in
    2. Hot water out
    3. Central heating in
    4. Central heating out
    5. Condensate drain

    Or any of the fittings connecting to these systems.

    Photo perhaps?

    Hello,

    It's a bit difficult to get a photo from the underneath but I think these will show what I mean.

    It's the white downpipe it has come detached twice, as mentioned before, I've followed it into the house where I think it joins the sink waste.

    Hope you can see my album called "boiler" not sure how to incorporate the photos in the message.

    Thank you.

    Its not clear exactly what the connection is from your photo.

    From memory I think its just a male outlet which pushes inside the white drain pipe. If so then as Dan says all that is needed is to put a clip on the pipe to stop it slipping down.

    But the good news is that its not dangerous and as long as you can catch any leakage then not even urgent.

    It is a trivial little connection, but if not fixed correctly can cause untold damage to the components.

    For what its worth I would just replace the condensate trap completely, there's a reason its leaking, and that reason is probably corrosion to the plastic parts, its not the sort of thing to come loose.

    This drain should drain away into a suitable waste, Vaillant also recommend the use of a U bend water seal, this may be because the fluid is smelly? not sure as this is essentially condensation...
    Although if you already do not have a u bend, I wouldn't bother putting one in now.

    It's not the trap that is leaking, as said the pipe is not clipped so it detaches itself from the male connection on the boiler.
