Immersion boiler help

    Hey all, so two days ago moved into a new apartment and everything seemed great. However yesterday the sink in the bathroom lost a whole lot of pressure and the toilet cistern started taking agggggges to re-fill. I just thought: "OK, well the pressures been building up for a while, no problem I guess".

    So anyway this morning nothing worked, no pressure anywhere (for cold water, with the pump on the hot water works fine) so I took a look at the boiler for the fist time. I noticed that two valves were twisted shut, the "cold feed to copper cylinder" (although it goes to the pump as in the pics) and the "overflow & vent" valve (both of these are the highest two red valves in the pictures).

    Turning on the cold feed helped the toilet situation, and turning on the pump (which was also off) now makes the sink in the bathroom and the shower work (although with an almighty noise from the pump which scared the bejaysus out of me the first time). So I said to myself "hey, the overflow should be open too right? In case it...well... overflows"?

    However when I open it theres just a huge rush of water getting into the top tank (it sounds like), and it went unabated for maybe 5 minutes before I got worried and shut it off again. Is it just labeled wrong (or did I read it wrong?) should an overflow make that much noise, if any? Should I leave it open or not?

    Pics attached.

    The top valve is the cold feed to the header tank which feeds the cylinder below, open it and allow it to fill, see how it goes.

    As already said , open the top valve , this is the mains supply to the cold water section of the cylinder the over flow is the copper pipe you see below it , the rush of water you hear is the tank filling , when its full theballcock will shut the water off, dont use the pump until the tank is full or you will end up dry running the pump which is not a good idea especially as i presume you have a negative head pump which are big bucks to replace.

    Thanks! Seems to be the same as before, but at least the noise stopped. Also, having never lived with one before (or at least one I've ever seen/interacted with) should you leave the pump switched on all the time or just turn it on when having a shower/using the sink? Or does it even matter?

    The pump is usually left switched on as its only activated when a tap is opened or the toilet flushed , but some people leave it switched off at night so the noise does not wake other people in the house/apartment when someone uses the loo in the middle of the night.
