Toilet spits a little squirt of water every few minutes into bowl?

[justneedsomehelpthanks]

Hi all!


Recently, a Plumber came to install new parts into toilet (black pump?) but this new random squirts seem weird.


Every few minutes or less (though pretty random), a little squirt / spit of water will happen for about 1 second or so. Not a full flush at all. Just a little jet of water as though the toilet was spitting into the toilet (from the back left side).
Any ideas? I presume the plumber might need to make another visit.
Thanks

It means the water level is slightly too high and a little bit of water is escaping through the overflow. Are you local to Essex

Do you have a photo of the new part?
And are you saying that when the toilet goes to flush, that water squirts a jet of water in to the bowl from the left side of the tank?
