Is this weird noise a kind of sucking noise, either way you have to find the pump.

 

[Gossamer]

Yes sort of. A sucking / clicky noise. Gulping?

They are noisy by design but sometimes things can be done. Need a photo of the pump.

Ok ill try to get a picture, will it be in the floor or nearby in a cupboard?

May not be in plain sight but shouldnt be in the floor, follow the noise.

Hi. Ok found the pump see attached pics.
Running it sounds ok makes a whirring sound. The gulping annoying sound comes from the drain in the shower in first pic I posted.
