Usage Tip The most common problem with this and other larger air pumps is premature diaphragm tearing due to excessive back pressure. If an air pump is powering too small of a diffuser or too few outlets, excessive back-pressure can occur. The solution is to add a tee with a ball valve or other 'bleeder valve' so that excessive air can be bled off into the atmosphere. Start with the valve completely open and slowly close it until you have the maximum output from your air diffusers without unnecessary back pressure.
