I am glad it was DOA, because it would have done damage if it had started leaking after installation in a difficult to get to place. ## Features - WHAT WILL YOU GET - You will get a 12V R385 diaphragm pump, air pump working voltage is DC 12V; Maximum flow is 1.5-1.8L/Min. - WARM TIPS - Don't run continuously.
