    Hi All,

    I have a minor leak in a component which I can't identify on my Megaflow system. I first thought it was some kind of pressure relief valve, but there is a more obvious one of those directly before it in the flow. It's on the inlet pipe for the hot water supply - the pipe just drops back down and then enters the cylinder at the bottom. It doesn't have any branches coming off it or anything. I have circled it in red in the pics below.

    Can someone tell me what it is? Is it servicable or does it need to be replaced? The leak is coming out the very centre in the front of it (you can see where in the first pic where the brown rust stains are).

    Thanks a lot for any help,
    Darim

    Its the pressure reducing valve. They often leak there.

    The insert is usually available although as the cost is not a lot different many like to replace the whole assembly as thats usually quicker than cleaning the old one.

    A special qualification is required to work on unvented cylinders so the only advice I would give you is to get someone who is qualified like Chris R who posts here and is also "somewhere in Surrey".
