    Thanks all. The old leakage is from years back - nothing is leaking now. I’ll ask a G3 engineer to take a look (when I can afford it). For now the tundish is clear so hoping nothing needs doing this second.

    Random question again. Sorry! Keen to get this looked at soon and as the G3 engineers I’ve had before haven’t picked up on any of this (the long G1 and the additional stop cock) I’m wondering where I’m best to find a decent trustworthy engineer? I’m based in Hertfordshire (Ware/Hertford). Thanks.

    You could also post on the Find a plumber, tiler...section of this forum, on the find a plumber part. Worth a try.
    Or ask around your area who folk think is a decent and experienced plumber. Although take all recommendations as not guaranteed, because only a plumber knows how good the standard of plumbing work really is.
    The pipework that is too long is termed the D1 pipe. (It is short for Discharge 1 pipe)

    Why is there no expansion vessel connected to composite valve? Also discharge pipework is non-compliant with regs. Get a GOOD G3 plumber in to check over and service :)

    Thanks. I’ve posted on the other forum.

    There is a silver expansion vessel on top of the tank, plus a red one on the wall (I think for heating). Sorry that’s vague!

    D2 is def not to regs. Minimum of 300mm unbent pipe from the tundish before any bends.
    One more voice to get a G3 plumber in to look.
    Also, and seriously, you didn't answer the earlier question of whether you get it serviced.
    It NEEDS to be done each year. Looking at the pressure reducing valve I see no evidence of the mech being removed in order to clean the strainer.
    The fact is, if you have a leak on your HW system and end up claiming MANY insurers will now demand to see your maintenance history before even considering your claim. Remember all they want to do is make money NOT look after you. So, they look for every way out they can find...

    I do notice however that both the pressure relief AND the temp & pressure relief valves have been changed. Shame the person never did any proper maintenance.

    There should be an uninterrupted supply to the cylinder from the group set (no valves/take offs/stop taps). Balanced cold should be taken from the group set. D1 & D2 do not comply (bends/lengths)

    Hi all! Sorry to reignite this post. Good news - I had a G3 engineer visit today which has fixed the above issues, as well as repressuring the vessel.

    I might just be worrying a bit too much, but the tundish is NOT dripping, but is damp. I.e. putting some tissue under it for 15mins shows a couple of drops. Watching it for a while shows nothing. Is this just condensation / is it normal? Just to clarify there's no visible drip at all.

    Did he replace the valve eg the one that's connected to the tundish ?
