    Morning all,

    can anyone help with some advice on fixing an issue which started last night.

    I have lost over 50% of my cold water feed from my water tank. Normally good enough pressure for shower & taps & nothing has been altered & the tank is still filling up.

    what checks can I do to fix the issue?

    If its happening at shower and tsps it would suggest some blockage on outlet pipe to tank, can't imagine what that could be except dead bird/rat. Try putting hose down outlet and using mains pressure to jet through. Dont know how you can say ⁵⁰% unless you measured before and after?

    just an estimate at 50% as is far less than previous.

    Shouldn’t be a dead animal as it is well covered but possibly some limescale. I’ll drain it down & see if I can dislodge it with a hose.

    thank you.

    Do you mean the flow from taps is a lot less on hot and cold ? Or just the cold ? Is kitchen tap cold working ok ?

    The cold taps are reduced by a lot, the hot may be effected slightly (but that may be just me over thinking it). The hot taps are fed by the hot water cylinder which I believe is gravity pressured by the tank above in the loft.

    the kitchen tap is mains feed which is normal pressure.

    Then you either have a restriction in the pipework or an air lock.
