A debris trap for capturing debris flowing in a stream of liquid, the debris trap includes a housing, a fluid inlet channel in connection with a space in the housing, a fluid outlet channel in connection with the space, the fluid outlet channel comprising a fluid outlet port, a float member, a guide element configured to guide movement of the float member when a liquid level in the space changes when in use, a stopper in connection with the fluid outlet port configured to stop the movement of the float member when the liquid level in the space raises, the fluid outlet port which, when the float member is against the stopper, remains partially open and the float member, when brought against the stopper, form a fluid communication path with a reduced area, which restricts the size of the debris capable of flowing through the outlet port.
