in THE MAIN WALL
Rinnai E50 combo de aerator leaking water out of the top, there is no cap on the top, and likely never was one since new, 2 questions.
1) should it leak out of top
2) Is the original likely to have metric threads and can I replace it with a non factory part.
would the lack of a cap be a cause of the problem. stem for the missing cap is rusted.
Combi boiler has been in service for about 5 years, so it has been leaking for some time.

    We really do need a little help, first should there be water coming out of the top of the de aerator?

    Geeeeeze, I thought that you were asking a question about a real Deaerator that you would see in a commercial/industrial boiler plant.

    Thank you Nielc, that is of course what we expected, so the second part of the question, is there any reason we cannot swap the de aerator for a similar sized one that is not a Rinnai product, as Rinnai is out of stock.

    an air vent is an air vent,
    as long as threads match, and it physically fits, , ,

    I guess if you're still in warrantee, I would get written blessings from Rinnai first
