    "Hi. It seems to me like it could be the ball float valve needs replacing, or there could be an airlock. Either way i would
    get a plumber in ASAP.
    Hope that helps."

    "Hi Allan, hope you are well.
    Without looking it’s hard to guess but I’d change the inlet valve the diaphragm usually sticks causing it not to fill can’t see why you’d get an air lock on the cold supply as it usually feeds off the mains.
    Hope this helps.
    Kind regards,
    Gavin"

    "Hi there have you had any water works done recently. Sounds like your water entry valve may need replacement"

    "There’s every possibility the ball valve has seized and may need replacing, if you have a gravity-fed system there is a chance it could be an air lock but more likely to be a faulty ball valve"

    "Possibly ball valve stuck. Unless the toilet is tank fed from a header tank it’s unlikely to be a airlock."

    "I would agree with the other responder. Could also be “crud/scale” blocking/seizing up the valves, washers, or mechanical parts. Unlikely to be an airlock. Sometimes it’s worth isolating the supply, removing the fill mechanism; taking apart what you can and giving it a good clean up and replacing washers/diaphragms etc with new."

    "Hi

    This sounds like the inlet float valve is faulty or it maybe just stuck in the off position. Remove the cistern lid and check that the valve is free by flushing the toilet and the float should lower and start filling if it is free then the valve is faulty and needs replacing. Quite a straight forward job for a professional plumber.

    Regards Steve"

    "Hi there

    If your cistern has suddenly stopped filling up it is most likely that that float valve will need to be replaced.

    Kind regards
