Air leaks are found on the suction side of the system. Common areas would include the pump lid, pump intake, diverter valves, fittings, and vacuum hoses. The pump must be turned on to identify the location of any suction leaks.

Mix some dish soap and water until it creates some good soapsuds. Spread the soapsuds along the suspected leak areas. If there is an air leak, the soapsuds will be sucked in. This is our favorite method. It’s very easy to recognize the movements of the bubbles if there is an air leak.

Using the smoke from lit incense stick is one way to find an air leak. Hold the incense close to a suspected air leak. If there is a leak, the smoke will be drawn in. This method works well but it works best on a non-windy day.
