Problem with Toilet after Water Main Repair

    I’m hoping someone can help me because I’m at a loss! The water main in my town burst yesterday and we were without water for about 14 hours. Neither I or my partner were home for most of the day so it wasn’t a problem. Since we got home and flushed the toilet, the cistern has been constantly refilling, to the point where it’s overflowing the pipe inside and trickling very slowly into the bowl. It’s been making noise all night. I’ve opened it up for a look but I can’t see what’s wrong. EDIT- Photos below, if anyone has any advice I would be very grateful!

    Toilet would be fed from a tank in the attic normally I think. I don't think it's related to the water main. A floating ball cock normality tells the water when to stop. Maybe it's set a bit high?

    This toilet doesn’t seem to have a standard floating ballcock. With the timing I was sure it had to be something to do with the water being off for so long yesterday but now I don’t know what to think. I might have to ring someone to come take a look at it, was hoping it would be an easy fix.

    I'm not a plumber, but had a similar problem to you with water constantly running into the bowl as the toilet push buttons were not releasing properly. The buttons are connected to a cartridge which I think is called a siphon and at the bottom of the siphon is a rubber washer. Your problem may be an accumulation of dirt around this washer - if the mains was off you often get an initial intake of dirty water into the system so it is possible some dirt or grit has accumulated in this area. Anyway, worth trying this fix which does not require any tools:

    In my case my problem magically resolved itself after switching off the water mains, flushing the loo, then refilling the cistern.

    Don't take the flush valve out as the water is rising to the level of the overflow pipe, which indicates that the problem is with the filling valve

    On the arm of the filling valve, gently lift it up and push it down a few times, it might just be stuck.
    If that doesn't help, gently hold it down fully for about a minute, if there is a bit of dirt stuck in it, it may flush through.
    Failing that, the top of the filling valve will need to be dismantled for cleaning, or replacing the diaphragm.
