Over time, the self-lubricating tubing will start to age, and can also cause excess resistance and unnecessary wear on the motor. How to Replace Step 1: Hold down the sides of the DŌS Head and the clips will release. Remove the pump head and set it aside. Step 2: Pick up your new pump head and slip it right down into the old heads position and the clips should click into place. Test the Pumps rotation with the manual priming buttons.
