Toilet overflowing after flush

[Darren Singleton]

Hi All

I have a push button system, and after returning from holiday when the toilet is flushed it is overflowing into the bowl.

What I have noticed though, is if i run a tap for a few seconds it stops.

Any suggestions or help on how to resolve? Thanks all

Either your flush valve isn't fully closed or inlet isn't closing. Take top off cistern, is it going over the overflow?

Your flush valve must not be closing fully then. Some can be twisted and removed for cleaning. If you're lucky it'll be a bit of debris on the bottom preventing full closure. Inlet needs to be shut off first.

Thanks. I’ve turned my water pressure down and it’s solved the issue for now. Would this be a normal solution?

Not with those symptoms

If the water is going down the overflow (at the top of the flush valve) then your inlet valve is at fault.

Probably needs diaphragm cleaning or replacing.

If water is escaping out of the outlet (at the bottom of the flush valve) then the flush valve is not seating properly and needs a new seating washer or cleaning.

Totally misread this, your inlet valve is at fault
