Water pump...if everyone can keep their cool!

I added a braided vinyl loop on the output side of the water pump. See pic below. The tubing came in a 10' pack at HD, so I just used the whole 10'. It quieted the pump down by many magnitudes. You can still hear it, but I didn't want it to go silent, so that I would know if the fresh water tank ran dry, etc. It used to wake myself or the DW up when either of us flushed the toilet during the night, but it's so quiet now that I doubt that will be a problem anymore.

Thanks to SoundGuy and Lynnmor for your advice freely offered! It was very helpful for this project.
