Quieter Water Pump

That rattling of pipes is probably a huge part of the noise. Last I read these newer, quieter pumps actually use more water. Regardless though, the old school pumps really can be made to run quiet using the info already shared. My pump is mounted on cross sections of hose (similar to radiator hose) which increase the sound isolation. It's then attached on input and output to flexible hose, which connects to the pex. The pex is shielded from the walls with foam where it's accessible. The accumulator reduces the frequency and run time of the pump as well as absorbing noise. My pump won't run at all for midnight excursions to the restroom.
