So we've been so annoyed by our loud water pump. The neighboring campsites have even asked what the loud noise was that came on when we ran our sink and shower. Decided to replace the water pump with a newer upgraded model. Wow, what a difference!! Instead of a loud growl, now a quieter sound. We upgraded with the SHURflo 12V 3.0 GPM RV Water Pump 4008-101-A65 Revolution below.
