Diaphragm pump leak detection

A diaphragm pump leak detection device comprising:

• a body comprising:
• an airflow inlet;
• an airflow outlet arranged to substantially align with the airflow inlet;
• and
• a liquid reservoir in a bottom portion of the body;
• a liquid separator positioned directly between the airflow inlet and the airflow outlet, the liquid separator dividing an airflow path from the airflow inlet to the airflow outlet into at least two separate flow paths around the liquid separator, wherein the liquid separator comprises:
• a cylinder coupled to the body and positioned directly between the airflow inlet and the airflow outlet, and
• a sleeve configured to interface with a lower portion of the cylinder, the sleeve comprising a channel, wherein a first end of the channel terminates at the lower portion of the cylinder and a second end of the channel opens to the liquid reservoir;
• and
• a liquid level detector at least partially contained within the channel, wherein the channel is in liquid communication with the liquid reservoir.
